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
