All Implemented Interfaces:

InjectionProvider

public class DefaultInjectionProvider
extends Object
implements InjectionProvider

Worker for the Inject annotation that delegates out to the master MasterObjectProvider to access the value. This worker must be scheduled after certain other workers, such as BlockInjectionProvider (which is keyed off a combination of type and the Inject annotation).

Description copied from interface: InjectionProvider

Peform the injection, if possible. Most often, this will result in a call to ClassTransformation.injectField(String, Object). The caller is responsible for invoking ClassTransformation.claimField(String, Object).

Specified by:

provideInjection in interface InjectionProvider

Parameters:

fieldName - the name of the field requesting injection

fieldType - the type of the field

locator - allows services to be located

transformation - allows the code for the class to be transformed

componentModel - defines the relevant aspects of the component

Returns:

true if an injection has been made (terminates the command chain), false to continue down the chain
