What's New With 6.6.0

Major Updates
WireBox Child Injectors
Welcome to the world of hierarchical dependency injection.  We had the ability before to add a parent injector to WireBox, but now you can not only add a parent, but also many children to the hierarchy.
Every injector has the capability to store an ordered collection (ordered struct) of child injectors via the childInjectors property. Child injectors are used internally in many instances to provide a hierarchical approach to DI where instances can be searched for locally, in the parent and in the children. Here are some of the new methods to assist with child injectors:
hasChildInjector( name ) - Verify if a child injector has been registered
registerChildInjector( name, child ) - Register a child injector by name
removeChildInjector( name ) - Remove a child injector by name
getChildInjector( name ) - Get a child injector by name
getChildInjectors() - Get all the child injectors registered
getChildInjectorNames() - Get an array of all the registered child injectors
Child Enhanced Methods
getInstance()
The getInstance()method now has an injector argument so you can EXPLICITLY request an instance from a child injector by name getInstance( name : "service", injector : "childInjector" )
Apart from the explicit lookup it can also do implicit hierarchical lookups using the following order:
Locally
Parent
All Children (in order of registration)
containsInstance( name ) - This method now also searches in the child collection for the specific name instance. The lookup searches in the following order:
1.Locally
2.Parent
3.Children
shutdown() - The shutdown method has been enhanced to issue shutdown method calls to all child injectors registered.
Getting Instances From Specific Child Injectors
The getInstance() has been modified to have an injector argument that you can use to specifically ask for an instance from that child injector. If the child injector has not been registered you will get a InvalidChildInjector Exception.
getInstance( name: "CategoryService", injector : "ChildInjector" )
Child Injector Explicit DSL
The following is the DSL you can use to explicitly target a child injector for a dependency. You will prefix it with wirebox:child:{name} and the name of the injector:
// Use the property name as the instance name
property name="categoryService" inject="wirebox:child:childInjector"
// Use a specific instance name
property name="categoryService" inject="wirebox:child:childInjector:CategoryService"
// Use any DSL
property name="categoryService" inject="wirebox:child:childInjector:{DSL}"
IInjector Interface Updates
The coldbox.system.ioc.IInjector interface's getInstance() method has been modified to include support for child injector retrievals:
/**
 * Locates, Creates, Injects and Configures an object model instance
 *
 * @name The mapping name or CFC instance path to try to build up
 * @initArguments The constructor structure of arguments to passthrough when initializing the instance
 * @dsl The dsl string to use to retrieve the instance model object, mutually exclusive with 'name'
 * @targetObject The object requesting the dependency, usually only used by DSL lookups
 * @injector The child injector name to use when retrieving the instance
 */
function getInstance(
	name,
	struct initArguments,
	dsl,
	targetObject = "",
	injector
);
Release Notes
WireBox
