Class ReflectionWorld

java.lang.Object

org.aspectj.weaver.World

org.aspectj.weaver.reflect.ReflectionWorld

All Implemented Interfaces:

Dump.INode, IReflectionWorld

public class ReflectionWorld
extends World
implements IReflectionWorld

A ReflectionWorld is used solely for purposes of type resolution based on the runtime classpath (java.lang.reflect). It does not support weaving operations (creation of mungers etc..).

resolveUsingClass

public ResolvedType resolveUsingClass(java.lang.Class<?> clazz)

Resolve a type using the specified class. Normal resolution in a reflection world uses Class.forName() via the classloader (attached to this world) in order to find a named type then builds a reference type and a reference type delegate based on that. For some classes generated at runtime (e.g. proxy or lambda representation) the forName() call will not work. In those situations we should just use the clazz we have. Should the whole thing switch from using forName() to using the clazz objects? Possibly but that introduces a lot of change and we don't have a lot of test coverage for this scenario (reflection world). What we are doing right now is that this can optionally be used if the regular resolution scheme did not work. Although AspectJ is *not* multi threaded or re-entrant, Spring doesn't always respect that. There might be an issue here if two attempts are made to resolve the same thing at the same time via this method.

Parameters:

clazz - the class to use as the delegate for the resolved type

resolveDelegate

protected ReferenceTypeDelegate resolveDelegate(ReferenceType ty)

Description copied from class: World

Find the ReferenceTypeDelegate behind this reference type so that it can fulfill its contract.

Specified by:
