This pattern uses a central registry know as the "Service Locator" to request either Singleton instances or make use of a factory to generate instances of a particular type. This pattern simplifies component-based application where all applications dependencies are cleanly listed at the beggining of the application boostrap. 6 | 7 | ### Motivation 8 | To simplify the classes relationships and dependencies, defining a single point of class registration and request. To reduce software development complexity 9 | 10 | ### Advantages 11 | - Simplifies the use of singleton and static objects 12 | - Centralize the use of objects in one class called locator 13 | - The code is easy to test 14 | 15 | ### Install 16 | ##### Copy the includes [folder](https://github.com/rsaz/ServiceLocator/tree/master/include/slocator) to your build tree and use a C++ compilter >= 11 17 | ``` 18 | 19 | $ git clone https://github.com/rsaz/ServiceLocator.git 20 | 21 | ``` 22 | ### Platforms 23 | - Windows (msvc 2013+, cygwin) 24 | 25 | ### Package Manager 26 | 27 | ### Features 28 | - Register service ```RegisterService()``` 29 | - Unregister service ```UnregisterService()``` 30 | - Request service ```Get()``` 31 | - Request service list ```ServicesList()``` 32 | - Register service factory ```RegisterServiceFactory()``` 33 | - Unregister service factory ```UnregisterServiceFactory()``` 34 | - Request service factory ```Get()``` 35 | - Request service factory list ```ServicesFactoryList()``` 36 | 37 | ### Usage examples 38 | ```c++ 39 | // Class Examples 40 | using Locator::ServiceLocator; 41 | 42 | #pragma region Classes Examples 43 | class ILogger 44 | { 45 |
