MonkeyInject

A dependency injection framework for ConnectIQ Applications

Bind Classes to interfaces, declare your dependencies, and let MonkeyInject handle building.

Usage

Modules

Modules are where you bind your interfaces to concrete classes. Create your own Module class and extend the MonkeyInject.Module that is included in the library.

Modules bind interfaces, described by symbols to ClassDefs.

class ConcreteWriteable {
  function write(){
    // Do some work.
  }
}

class MyModule extends MonkeyInject.Module {
  function initialize() {
    Module.initialize();

    bind(:Writeable)          // Bind the Writeable Interface
      .to(ConcreteWriteable); // To the ConcreteWriteable class
  }
}

Bindings support different scopes, to determine when a new instance of the concreate class will be created. Read about Bindings in the Wiki (todo).

Kernel

The entry point for the library is the Kernel object. Instantiate the kernel, load modules, and call build(). The framework will then handle building all of the appropriate dependencies and will return a fully initialized implementation of the interface requested.

class MyApp extends Application.App {
  private var _writeable;
  private var _kernel;

  function initialize() {
    _kernel = new MonkeyInject.Kernel();
    _kernel.load(new MyModule());

    _writeable = _kernel.build(:Writeable);
  }
}
