public class MethodDelegateTypeMunger
extends ResolvedTypeMunger

Type munger for annotation style ITD declare parents. with an interface AND an implementation. Given the aspect that has a field public static Interface fieldI = ... // impl. we will weave in the Interface' methods and delegate to the aspect public static field fieldI Note: this munger DOES NOT handles the interface addition to the target classes - a regular Parent kinded munger must be added in coordination.

existsToSupportShadowMunging

public boolean existsToSupportShadowMunging()

Description copied from class: ResolvedTypeMunger

Some type mungers are created purely to help with the implementation of shadow mungers. For example to support the cflow() pointcut we create a new cflow field in the aspect, and that is added via a BcelCflowCounterFieldAdder. During compilation we need to compare sets of type mungers, and if some only come into existence after the 'shadowy' type things have been processed, we need to ignore them during the comparison. Returning true from this method indicates the type munger exists to support 'shadowy' stuff - and so can be ignored in some comparison.

Overrides:

existsToSupportShadowMunging in class ResolvedTypeMunger

tagAsReplacingExistingMethod

public void tagAsReplacingExistingMethod()

isReplacingExistingMethod

public boolean isReplacingExistingMethod()
