Class CFGMethodAdapter

java.lang.Object

org.objectweb.asm.MethodVisitor

org.evosuite.graphs.cfg.CFGMethodAdapter

public class CFGMethodAdapter
extends org.objectweb.asm.MethodVisitor

Create a minimized control flow graph for the method and store it. In addition, this adapter also adds instrumentation for branch distance measurement defUse, concurrency and LCSAJs instrumentation is also added (if the properties are set).

Field Detail

EXCLUDE

public static final List<String> EXCLUDE

A list of Strings representing method signatures. Methods matching those signatures are not instrumented and no CFG is generated for them. Except if some MethodInstrumentation requests it.
