Copyright and Related Rights. A Work made available under CC0 may be 41 | protected by copyright and related or neighboring rights ("Copyright and 42 | Related Rights"). Copyright and Related Rights include, but are not 43 | limited to, the following: 44 | 45 | i. the right to reproduce, adapt, distribute, perform, display, 46 | communicate, and translate a Work; 47 | ii. moral rights retained by the original author(s) and/or performer(s); 48 | iii. publicity and privacy rights pertaining to a person's image or 49 | likeness depicted in a Work; 50 | iv. rights protecting against unfair competition in regards to a Work, 51 | subject to the limitations in paragraph 4(a), below; 52 | v. rights protecting the extraction, dissemination, use and reuse of data 53 | in a Work; 54 | vi. database rights (such as those arising under Directive 96/9/EC of the 55 | European Parliament and of the Council of 11 March 1996 on the legal 56 | protection of databases, and under any national implementation 57 | thereof, including any amended or successor version of such 58 | directive); and 59 | vii. other similar, equivalent or corresponding rights throughout the 60 | world based on applicable law or treaty, and any national 61 | implementations thereof. 62 | 63 | 2. Waiver. To the greatest extent permitted by, but not in contravention 64 | of, applicable law, Affirmer hereby overtly, fully, permanently, 65 | irrevocably and unconditionally waives, abandons, and surrenders all of 66 | Affirmer's Copyright and Related Rights and associated claims and causes 67 | of action, whether now known or unknown (including existing as well as 68 | future claims and causes of action), in the Work (i) in all territories 69 | worldwide, (ii) for the maximum duration provided by applicable law or 70 | treaty (including future time extensions), (iii) in any current or future 71 | medium and for any number of copies, and (iv) for any purpose whatsoever, 72 | including without limitation commercial, advertising or promotional 73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each 74 | member of the public at large and to the detriment of Affirmer's heirs and 75 | successors, fully intending that such Waiver shall not be subject to 76 | revocation, rescission, cancellation, termination, or any other legal or 77 | equitable action to disrupt the quiet enjoyment of the Work by the public 78 | as contemplated by Affirmer's express Statement of Purpose. 79 | 80 | 3. Public License Fallback. Should any part of the Waiver for any reason 81 | be judged legally invalid or ineffective under applicable law, then the 82 | Waiver shall be preserved to the maximum extent permitted taking into 83 | account Affirmer's express Statement of Purpose. In addition, to the 84 | extent the Waiver is so judged Affirmer hereby grants to each affected 85 | person a royalty-free, non transferable, non sublicensable, non exclusive, 86 | irrevocable and unconditional license to exercise Affirmer's Copyright and 87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the 88 | maximum duration provided by applicable law or treaty (including future 89 | time extensions), (iii) in any current or future medium and for any number 90 | of copies, and (iv) for any purpose whatsoever, including without 91 | limitation commercial, advertising or promotional purposes (the 92 | "License"). The License shall be deemed effective as of the date CC0 was 93 | applied by Affirmer to the Work. Should any part of the License for any 94 | reason be judged legally invalid or ineffective under applicable law, such 95 | partial invalidity or ineffectiveness shall not invalidate the remainder 96 | of the License, and in such case Affirmer hereby affirms that he or she 97 | will not (i) exercise any of his or her remaining Copyright and Related 98 | Rights in the Work or (ii) assert any associated claims and causes of 99 | action with respect to the Work, in either case contrary to Affirmer's 100 | express Statement of Purpose. 101 | 102 | 4. Limitations and Disclaimers. 103 | 104 | a. No trademark or patent rights held by Affirmer are waived, abandoned, 105 | surrendered, licensed or otherwise affected by this document. 106 | b. Affirmer offers the Work as-is and makes no representations or 107 | warranties of any kind concerning the Work, express, implied, 108 | statutory or otherwise, including without limitation warranties of 109 | title, merchantability, fitness for a particular purpose, non 110 | infringement, or the absence of latent or other defects, accuracy, or 111 | the present or absence of errors, whether or not discoverable, all to 112 | the greatest extent permissible under applicable law. 113 | c. Affirmer disclaims responsibility for clearing rights of other persons 114 | that may apply to the Work or any use thereof, including without 115 | limitation any person's Copyright and Related Rights in the Work. 116 | Further, Affirmer disclaims responsibility for obtaining any necessary 117 | consents, permissions or other rights required for any use of the 118 | Work. 119 | d. Affirmer understands and acknowledges that Creative Commons is not a 120 | party to this document and has no duty or obligation with respect to 121 | this CC0 or use of the Work. 122 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 2 | # Design Patterns In The Apex Programming Language 3 | ![CI Workflow](https://github.com/bdJohnson72/Design-Patterns-In-Apex/actions/workflows/main.yml/badge.svg) 4 | 5 | 6 | ![recipes-logo](recipes-logo.png) 7 | 8 | Few things have helped me more in my career than understanding how you use the Object Oriented Features of Apex to write 9 | code that is flexible, testable and maintainable.

Code is based on Head First Design Patterns 24 | - [UML diagram](https://github.com/bdJohnson72/Design-Patterns-In-Apex/blob/master/UML/simple%20factory/Simple%20Factory.png) 25 | 26 | #### [The Reflective Factory](https://github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/ReflectiveFactory) 27 | 28 | -[Watch on YouTube](https://www.youtube.com/watch?v=zNuOWwIl-xo&t=1322s) 29 | 30 | This can be a bit more involved but is also the ultimate in closed for modification but open for extension. By making 31 | our factory reflective we never need to update it when we add new concrete types. 32 | 33 | - Unique to Apex and Salesforce. Refactor the simple factory pattern with custom metadata. Wow your colleagues with the 34 | Type class. One of my favorite Apex party tricks. 35 | 36 | #### [The Factory Method](https://github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/SimpleFactory) 37 | 38 | -[Watch on YouTube](https://www.youtube.com/watch?v=xC86Aof8bV4&t=10s) 39 | 40 | Another implementation using the pizza example from Head First Design Patterns. What do we do if we want our Pizza Store 41 | to access different factories? 42 | 43 | #### [The Singleton](https://github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/singleton) 44 | 45 | -[Watch on YouTube](https://www.youtube.com/watch?v=f4n0oyYcvtw) 46 | 47 | An easy pattern to understand and always useful for keeping your governer limits under control 48 | 49 | ## Behavioral Design Patterns 50 | 51 | These patterns are all about the communication between objects. How can objects cooperate to perform tasks. 52 | 53 | ### [The Observer](https://github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/Observer) 54 | -[Watch on YouTube](https://www.youtube.com/watch?v=w-yKRDCuDPI) 55 | 56 | When one object changes state we want to notify all the depenents. But we want to publisher and subscribers to be 57 | loosely coupled. 58 | 59 | ##Refactoring 60 | I have begun to add some of the examples from [Martin Fowler's Refactoring](amazon.com/Refactoring-Improving-Existing-Addison-Wesley-Signature/dp/0134757599/ref=sr_1_1?keywords=refactoring&qid=1655299896&s=books&sprefix=refacto%2Cstripbooks%2C68&sr=1-1) 61 | and [Joshua Kerievsky's Refactoring to Patterns](amazon.com/Refactoring-Patterns-Joshua-Kerievsky/dp/0321213351) 62 | 63 | - [Composing Methods](github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/Refactoring/composing_methods) 64 | - [Simplifying Conditionals](github.com/bdJohnson72/Design-Patterns-In-Apex/tree/master/force-app/main/default/classes/Refactoring/simplify_%20conditionals) 65 | 66 | ## Read All About It 67 | 68 | Nothing in this repo would be possible without the books below.
