Java/Objective-C Bridge

4 | 5 |

This class library enables you to use any Objective-C library directly from Java without 6 | having to generate any Java class stubs. It is built on top of the powerful JNA library, 7 | and interacts with Objective-C through the C functions in the Objective-C runtime. 8 |

9 | 10 |

Features

11 | 12 |
    13 |
  1. Access To All Native Libraries and Frameworks
    2. 14 |
  2. No need to generate class stubs
    3. 15 |
  3. Two-Way Communication - Objective-C can use your Java objects 16 | just as your Java objects can use Objective-C objects.
    4. 17 |
  4. Annotations to mark Java methods that should be callable by Objective-C
    5. 18 |
  5. Very Thin Wrapper - so you don't have to learn a whole new way of working 19 | with Objective-C.
    6. 20 |
21 | 22 |

An Example

23 | 24 |

The following example shows the bridge being used to display an NSOpenPanel, 25 | and add a Java class as its delegate to listen for changes to the user selection:

26 | 27 | 28 |

Requirements

Installation

50 |
    51 |
  1. Add the ObjCBridge.jar and jna.jar files into your class path
    2. 52 |
  2. Add libjcocoa.dylib to your java.library.path
    3. 53 |
54 | 55 |

The Basics

56 | 57 |

The Java Cocoa bridge can be used at three levels of abstraction:

58 |
    59 |
  1. Low level : Direct calling of Objective-C runtime functions. E.g. objc_msgSend(), object_getClass(), etc... 60 | See Apple's documentation 61 | on the Objective-C runtime for details of what these methods do. You would use the {@link ca.weblite.Runtime Runtime.INSTANCE} singleton object 62 | to access these functions through the Java Cocoa Bridge. 63 |
    2. 64 | 65 |
  2. Mid level : Calling simplified procedural wrappers 66 | around the Objective-C runtime functions via the {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} class and its 67 | set of static methods. 68 |
    3. 69 | 70 |
  3. High level : Using the object-oriented API to interact with 71 | Objective-C objects and classes via Java wrapper objects. This method makes 72 | use of the {@link ca.weblite.objc.Client Client}, {@link ca.weblite.objc.Proxy Proxy}, 73 | and {@link ca.weblite.objc.NSObject NSObject} classes primarily. 74 |
    4. 75 |
76 | 77 | 78 |

The Low-Level API

The low-level API is nothing more than a JNA interface 81 | for the Objective-C runtime functions. 82 | If you are familiar with these functions, and you are comfortable calling them directly, then you are free to call this API directly. 83 | In most cases, however, you will likely want to use a higher level API that handles a bit more of the plumbing. 84 |

85 | 86 |

The following is a sample from the {@link ca.weblite.objc.RuntimeTest RuntimeTest} Unit test that makes use of this low-level API:

87 | 88 | 89 |

A few things to comment on here:

90 |
    91 |
  1. The {@code com.sun.jna.Pointer} class is used throughout this API to represent 92 | a C pointer. 93 |
    2. 94 |
  2. Many of the low-level API functions take a Pointer as a parameter and return pointers, however the objc_msgSend() method 95 | and its variants return a long rather than a Pointer. This is because the value returned by this method can be 96 | either a value or a pointer. 97 |
    3. 98 |
  3. 99 | Messages that take C strings (i.e. {@code const *char}) expect to receive a java string as a parameter. Messages that 100 | take NSStrings, however, will not accept Strings of this type. You need to provide a pointer to an NSString object 101 | in these cases. 102 |
    4. 103 |
104 | 105 |

The Mid-Level API

106 | 107 |

The mid-level API consists of a set of static convenience methods around commonly used functions of the Objective-C runtime API. 108 | These include:

109 | 118 | 119 |

Even if your are working with the high-level API, you will still likely need to use the mid-level API in some instances. For convenience, you may want to 120 | use a static import of all of the {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} static methods so that you can access them quickly and easily: 121 |

122 | 
{@code import static ca.weblite.objc.RuntimeUtils.*;}
123 | 124 |

The following sample code is taken from one of the unit tests and gives a good example of how to use the mid-level API to interact with 125 | the Objective-C runtime:

126 | 127 | 128 | 129 |

In order to provide a contrast with the low-level API, this example performs the same logic as the low-level 130 | example above. It makes use of the {@link ca.weblite.objc.RuntimeUtils#sel RuntimeUtils.sel()} function 131 | to obtain a selector rather than longer Runtime.INSTANCE.sel_getUid(). It also uses the cls() and clsName() 132 | functions to go back and forth between a class object and its class name. 133 |

134 |

However, we can shorten this still more. The {@code msg()} function includes a variant that accepts {@code String}s 135 | as their first two arguments. If the first argument is a {@code String}, then it is assumed to be a class name. If 136 | the second argument is a {@code String}, then it is assumed to be a selector name. Using this knowledge we can 137 | compress the above code significantly: 138 |

139 | 140 | 141 | 142 |
Using Type-Mapping
143 | 144 |

The {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} class also includes a few methods that act as a link and foundation 145 | to the higher level APIs. It includes a variant of the {@code msg()} function that can optionally perform type mapping 146 | of input arguments and their return values.

147 |

The method signature is as follows:

148 | {@code Object msg(boolean coerceOutput, 149 | boolean coerceInput, 150 | Pointer receiver, 151 | Pointer selector, 152 | Object... args)} 153 | 154 |

Note, that there are variants that allow you to specify the receiver or selector as strings also.

155 | 156 |

If you pass {@code true} for both {@code coerceOutput} and {@code coerceInput}, then the method will 157 | perform type mapping on the input {@code args} and the return value so that you are able to pass 158 | more familiar Java objects in. It will also perform type-checking to ensure that the correct 159 | variant of {@code objc_msgSend()} is sent to the Objective-C runtime (e.g. messages that return {@code float}s 160 | and {@code doubles} need to use the {@code objc_msgSend_fret()} function, and messages 161 | that return structures need to use the {@code objc_msgSend_sret()} function).

162 |

The type mapping is minimal and non-complex. There are just a few key mappings that are performed by 163 | this method:

164 |
    165 |
  1. Converts Java {@code String} objects to Objective-C {@code NSString} objects for arguments 166 | that are passed to messages that are expecting {@code NSStrings}. It uses the method signature 167 | of the method to determine if the transformation needs to be made. I.e. if a Java {@code String} 168 | is passed as an argument to a message that is expecting an Objective-C object (i.e. type encoding "{@literal @}"), 169 | then the string will be converted to an {@code NSString} automatically. 170 |
    2. 171 |
  2. Converts {@link ca.weblite.objc.Proxy Proxy} objects into {@code Pointer} objects for arguments 172 | that are expecting a Pointer or an Objective-C object. 173 |
    3. 174 |
  3. 175 | Automatically determines the correct variant of {@code objc_msgSend*} depending on the return type of 176 | the message (as specified in the Objective-C message signature). 177 |
    4. 178 |
  4. 179 | Converts return {@code NSString} return values to Java {@code String} objects. 180 |
    5. 181 |
  5. 182 | Wraps {@code NSObject} return values in {@link ca.weblite.objc.Proxy Proxy} objects so that 183 | they can be used more easily. It performs this conversion in a smart way using the {@link ca.weblite.objc.Proxy#load Proxy.load()} 184 | method to make sure that there is ever only one instance of a Java proxy for each instance of an Objective-C 185 | object. I.e. If a {@code Proxy} object already exists for a particular Objective-C object, then this method 186 | will look up the existing {@code Proxy} object and return that. Otherwise it creates a new {@code Proxy} object 187 | to wrap the return value and registers this proxy with the central proxy registry. 188 |
    6. 189 |
  6. Messages that return Structures will return a subclass of 190 | {@code com.sun.jna.Structure} 191 |
    7. 192 |
193 | 194 |

The following is some sample code taken from one of the unit tests to demonstrate how this variant of {@code msg()} can 195 | be used to enable automatic type mapping in the return values of Objective-c messages.

196 | 197 | 198 | 199 |

High-Level API (Object Oriented API)

200 | 201 |

Now that you see the foundation upon which the Java/Objective-C bridge sits, we can jump straight into the 202 | higher-level object oriented API. This API consists of three main classes that you'll wish to use.:

203 |
    204 |
  1. {@link ca.weblite.objc.Client Client} - An object that allows you to send messages to the Objective-C runtime. You'll generally 205 | use this to instantiate new Objective-C objects and obtain {@link ca.weblite.objc.Proxy Proxies} to them. 206 |
    2. 207 | 208 |
  2. {@link ca.weblite.objc.Proxy Proxy} - A wrapper around an Objective-C object that enables you to easily send messages 209 | to the native object. It includes convenience methods for sending messages that return various types. E.g. the {@link ca.weblite.objc.Proxy#sendInt sentInt()} 210 | method sends a message to which you expect an {@code int} to be returned. It returns a Java {@code int} so that 211 | you don't need to perform any ugly type casting. 212 |
    3. 213 | 214 |
  3. {@link ca.weblite.objc.NSObject NSObject} - A Java wrapper around an Objective-C object that enables two-way communication. Objective-C 215 | can call methods on this Java class, and you are able to send messages to the object's native Peer from Java. This is a subclass 216 | of {@link ca.weblite.objc.Proxy Proxy} so that it includes all of the same capabilities for sending messages. Typically you would subclass 217 | {@link ca.weblite.objc.NSObject NSObject} if you need to create a delegate for an objective-C object. You can define Java methods 218 | in your subclass that can be used in Objective-C via the {@link ca.weblite.objc.annotations.Msg Msg} annotation. 219 |
    4. 220 |
221 | 222 |

The following snippet is taken from a unit test. It shows the use of the {@link ca.weblite.objc.Client Client} class and {@link ca.weblite.objc.Proxy} 223 | class to create an NSMutable array and add some strings to it.

224 | 225 | 226 | 227 |

Writing a Delegate Class In Java

228 | 229 |

The {@link ca.weblite.objc.NSObject NSObject} class can be extended to define your own Java classes that can be called from Objective-C. 230 | You specify which methods can handle Objective-C messages using the {@link ca.weblite.objc.annotations.Msg Msg} annotation. There 231 | is an example at the top of the page that uses this method to add a delegate to the {@code NSOpenPanel} dialog. 232 |

The Basics

56 | 57 |

The Java Cocoa bridge can be used at three levels of abstraction:

58 |
    59 |
  1. Low level : Direct calling of Objective-C runtime functions. E.g. objc_msgSend(), object_getClass(), etc... 60 | See Apple's documentation 61 | on the Objective-C runtime for details of what these methods do. You would use the {@link ca.weblite.Runtime Runtime.INSTANCE} singleton object 62 | to access these functions through the Java Cocoa Bridge. 63 |
    2. 64 | 65 |
  2. Mid level : Calling simplified procedural wrappers 66 | around the Objective-C runtime functions via the {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} class and its 67 | set of static methods. 68 |
    3. 69 | 70 |
  3. High level : Using the object-oriented API to interact with 71 | Objective-C objects and classes via Java wrapper objects. This method makes 72 | use of the {@link ca.weblite.objc.Client Client}, {@link ca.weblite.objc.Proxy Proxy}, 73 | and {@link ca.weblite.objc.NSObject NSObject} classes primarily. 74 |
    4. 75 |
76 | 77 | 78 |

The Low-Level API

79 | 80 |

The low-level API is nothing more than a JNA interface 81 | for the Objective-C runtime functions. 82 | If you are familiar with these functions, and you are comfortable calling them directly, then you are free to call this API directly. 83 | In most cases, however, you will likely want to use a higher level API that handles a bit more of the plumbing. 84 |

85 | 86 |

The following is a sample from the {@link ca.weblite.objc.RuntimeTest RuntimeTest} Unit test that makes use of this low-level API:

87 | 88 | 89 |

A few things to comment on here:

90 |
    91 |
  1. The {@code com.sun.jna.Pointer} class is used throughout this API to represent 92 | a C pointer. 93 |
    2. 94 |
  2. Many of the low-level API functions take a Pointer as a parameter and return pointers, however the objc_msgSend() method 95 | and its variants return a long rather than a Pointer. This is because the value returned by this method can be 96 | either a value or a pointer. 97 |
    3. 98 |
  3. 99 | Messages that take C strings (i.e. {@code const *char}) expect to receive a java string as a parameter. Messages that 100 | take NSStrings, however, will not accept Strings of this type. You need to provide a pointer to an NSString object 101 | in these cases. 102 |
    4. 103 |
104 | 105 |

The Mid-Level API

106 | 107 |

The mid-level API consists of a set of static convenience methods around commonly used functions of the Objective-C runtime API. 108 | These include:

109 | 118 | 119 |

Even if your are working with the high-level API, you will still likely need to use the mid-level API in some instances. For convenience, you may want to 120 | use a static import of all of the {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} static methods so that you can access them quickly and easily: 121 |

122 | 
{@code import static ca.weblite.objc.RuntimeUtils.*;}
123 | 124 |

The following sample code is taken from one of the unit tests and gives a good example of how to use the mid-level API to interact with 125 | the Objective-C runtime:

126 | 127 | 128 | 129 |

In order to provide a contrast with the low-level API, this example performs the same logic as the low-level 130 | example above. It makes use of the {@link ca.weblite.objc.RuntimeUtils#sel RuntimeUtils.sel()} function 131 | to obtain a selector rather than longer Runtime.INSTANCE.sel_getUid(). It also uses the cls() and clsName() 132 | functions to go back and forth between a class object and its class name. 133 |

134 |

However, we can shorten this still more. The {@code msg()} function includes a variant that accepts {@code String}s 135 | as their first two arguments. If the first argument is a {@code String}, then it is assumed to be a class name. If 136 | the second argument is a {@code String}, then it is assumed to be a selector name. Using this knowledge we can 137 | compress the above code significantly: 138 |

139 | 140 | 141 | 142 |
Using Type-Mapping
143 | 144 |

The {@link ca.weblite.objc.RuntimeUtils RuntimeUtils} class also includes a few methods that act as a link and foundation 145 | to the higher level APIs. It includes a variant of the {@code msg()} function that can optionally perform type mapping 146 | of input arguments and their return values.

147 |

The method signature is as follows:

148 | {@code Object msg(boolean coerceOutput, 149 | boolean coerceInput, 150 | Pointer receiver, 151 | Pointer selector, 152 | Object... args)} 153 | 154 |

Note, that there are variants that allow you to specify the receiver or selector as strings also.

155 | 156 |

If you pass {@code true} for both {@code coerceOutput} and {@code coerceInput}, then the method will 157 | perform type mapping on the input {@code args} and the return value so that you are able to pass 158 | more familiar Java objects in. It will also perform type-checking to ensure that the correct 159 | variant of {@code objc_msgSend()} is sent to the Objective-C runtime (e.g. messages that return {@code float}s 160 | and {@code doubles} need to use the {@code objc_msgSend_fret()} function, and messages 161 | that return structures need to use the {@code objc_msgSend_sret()} function).

162 |

The type mapping is minimal and non-complex. There are just a few key mappings that are performed by 163 | this method:

164 |
    165 |
  1. Converts Java {@code String} objects to Objective-C {@code NSString} objects for arguments 166 | that are passed to messages that are expecting {@code NSStrings}. It uses the method signature 167 | of the method to determine if the transformation needs to be made. I.e. if a Java {@code String} 168 | is passed as an argument to a message that is expecting an Objective-C object (i.e. type encoding "{@literal @}"), 169 | then the string will be converted to an {@code NSString} automatically. 170 |
    2. 171 |
  2. Converts {@link ca.weblite.objc.Proxy Proxy} objects into {@code Pointer} objects for arguments 172 | that are expecting a Pointer or an Objective-C object. 173 |
    3. 174 |
  3. 175 | Automatically determines the correct variant of {@code objc_msgSend*} depending on the return type of 176 | the message (as specified in the Objective-C message signature). 177 |
    4. 178 |
  4. 179 | Converts return {@code NSString} return values to Java {@code String} objects. 180 |
    5. 181 |
  5. 182 | Wraps {@code NSObject} return values in {@link ca.weblite.objc.Proxy Proxy} objects so that 183 | they can be used more easily. It performs this conversion in a smart way using the {@link ca.weblite.objc.Proxy#load Proxy.load()} 184 | method to make sure that there is ever only one instance of a Java proxy for each instance of an Objective-C 185 | object. I.e. If a {@code Proxy} object already exists for a particular Objective-C object, then this method 186 | will look up the existing {@code Proxy} object and return that. Otherwise it creates a new {@code Proxy} object 187 | to wrap the return value and registers this proxy with the central proxy registry. 188 |
    6. 189 |
  6. Messages that return Structures will return a subclass of 190 | {@code com.sun.jna.Structure} 191 |
    7. 192 |
193 | 194 |

The following is some sample code taken from one of the unit tests to demonstrate how this variant of {@code msg()} can 195 | be used to enable automatic type mapping in the return values of Objective-c messages.

196 | 197 | 198 | 199 |

High-Level API (Object Oriented API)

200 | 201 |

Now that you see the foundation upon which the Java/Objective-C bridge sits, we can jump straight into the 202 | higher-level object oriented API. This API consists of three main classes that you'll wish to use.:

203 |
    204 |
  1. {@link ca.weblite.objc.Client Client} - An object that allows you to send messages to the Objective-C runtime. You'll generally 205 | use this to instantiate new Objective-C objects and obtain {@link ca.weblite.objc.Proxy Proxies} to them. 206 |
    2. 207 | 208 |
  2. {@link ca.weblite.objc.Proxy Proxy} - A wrapper around an Objective-C object that enables you to easily send messages 209 | to the native object. It includes convenience methods for sending messages that return various types. E.g. the {@link ca.weblite.objc.Proxy#sendInt sentInt()} 210 | method sends a message to which you expect an {@code int} to be returned. It returns a Java {@code int} so that 211 | you don't need to perform any ugly type casting. 212 |
    3. 213 | 214 |
  3. {@link ca.weblite.objc.NSObject NSObject} - A Java wrapper around an Objective-C object that enables two-way communication. Objective-C 215 | can call methods on this Java class, and you are able to send messages to the object's native Peer from Java. This is a subclass 216 | of {@link ca.weblite.objc.Proxy Proxy} so that it includes all of the same capabilities for sending messages. Typically you would subclass 217 | {@link ca.weblite.objc.NSObject NSObject} if you need to create a delegate for an objective-C object. You can define Java methods 218 | in your subclass that can be used in Objective-C via the {@link ca.weblite.objc.annotations.Msg Msg} annotation. 219 |
    4. 220 |
221 | 222 |

The following snippet is taken from a unit test. It shows the use of the {@link ca.weblite.objc.Client Client} class and {@link ca.weblite.objc.Proxy} 223 | class to create an NSMutable array and add some strings to it.

224 | 225 | 226 | 227 |

Writing a Delegate Class In Java

228 | 229 |

The {@link ca.weblite.objc.NSObject NSObject} class can be extended to define your own Java classes that can be called from Objective-C. 230 | You specify which methods can handle Objective-C messages using the {@link ca.weblite.objc.annotations.Msg Msg} annotation. There 231 | is an example at the top of the page that uses this method to add a delegate to the {@code NSOpenPanel} dialog. 232 |
