We also provide an interface to create objects that adhere to our injector interface: wirebox.system.ioc.IInjector. Then these objects can be used as parent injectors, which are great for legacy factories or creating hierarchies according to your specs. All you have to do is implement the following interface:
<cfinterfacehint="An interface that enables any CFC to act like a parent injector within WireBox"> <--- setParent ---> <cffunctionname="setParent"output="false"access="public"returntype="void"hint="Link a parent Injector with this injector"> <cfargumentname="injector"required="true"hint="A WireBox Injector to assign as a parent to this Injector"> </cffunction> <--- getParent ---> <cffunctionname="getParent"output="false"access="public"returntype="any"hint="Get a reference to the parent injector instance, else an empty simple string meaning nothing is set" > </cffunction> <--- getInstance ---> <cffunctionname="getInstance"output="false"access="public"returntype="any"hint="Locates, Creates, Injects and Configures an object model instance"> <cfargumentname="name"required="false"hint="The mapping name or CFC instance path to try to build up"/> <cfargumentname="dsl"required="false"hint="The dsl string to use to retrieve the instance model object, mutually exclusive with 'name'"/> <cfargumentname="initArguments"required="false"hint="The constructor structure of arguments to passthrough when initializing the instance"/> </cffunction> <--- containsInstance ---> <cffunctionname="containsInstance"output="false"access="public"returntype="any"hint="Checks if this injector can locate a model instance or not"> <cfargumentname="name"required="true"hint="The object name or alias to search for if this container can locate it or has knowledge of it"/> </cffunction> <--- shutdown ---> <cffunctionname="shutdown"output="false"access="public"returntype="void"hint="Shutdown the injector gracefully by calling the shutdown events internally."> </cffunction></cfinterface>
Once you create this CFC that implements this interface then you can call on the injector's setParent() method and you are ready to roll.
