Class InnerClassAccessMap

java.lang.Object

edu.umd.cs.findbugs.ba.InnerClassAccessMap

public class InnerClassAccessMap
extends java.lang.Object

Determine which methods are accessors used by inner classes to access fields in their enclosing classes. This has been tested with javac from the Sun JDK 1.4.x, but will probably not work with other source to bytecode compilers.

The instance of InnerClassAccessMap should be retrieved from the AnalysisContext.
