Copyright Since 2005 ColdBox Framework by Luis Majano and Ortus Solutions, Corp www.ortussolutions.com --- The WireBox injector is the pivotal class in WireBox that performs dependency injection. It can be used standalone or it can be used in conjunction of a ColdBox application context. It can also be configured with a mapping configuration file called a binder, that can provide object/mappings and configuration data. A WireBox Injector: Builds the graphs of objects that make up your application. Easy Startup: 

injector = new coldbox.system.ioc.Injector();
Binder Startup 
injector = new coldbox.system.ioc.Injector(new MyBinder());
Binder Path Startup 
injector = new coldbox.system.ioc.Injector( "config.MyBinder" );

    Method Detail

    autowire

    public any autowire(any target, [any<Mapping> mapping], [any targetID=''], [boolean annotationCheck='false'])

    I wire up target objects with dependencies either by mappings or a-la-carte autowires

    Parameters:
    target - The target object to wire up
    mapping - The object mapping with all the necessary wiring metadata. Usually passed by scopes and not a-la-carte autowires
    targetID - A unique identifier for this target to wire up. Usually a class path or file path should do. If none is passed we will get the id from the passed target via introspection but it will slow down the wiring
    annotationCheck - This value determines if we check if the target contains an autowire annotation in the cfcomponent tag: autowire=true|false, it will only autowire if that metadata attribute is set to true. The default is false, which will autowire anything automatically.
