      Get the self call graph for the class.

    • calledMethodIterator

      public Iterator<org.apache.bcel.classfile.Method> calledMethodIterator()
      Get an Iterator over self-called methods.

    • wantCallsFor

      public boolean wantCallsFor(org.apache.bcel.classfile.Method method)

      Parameters:
      method - the method
      Returns:
      true if we want call sites for the method, false if not

    • callSiteIterator

      public Iterator<CallSite> callSiteIterator()
      Get an Iterator over all self call sites.

    • hasSynchronization

      public boolean hasSynchronization()
      Does this class contain any explicit synchronization?

    • scan

      private void scan(CallGraphNode node) throws CFGBuilderException
      Scan a method for self call sites.
      Parameters:
      node - the CallGraphNode for the method to be scanned
      Throws:
      CFGBuilderException

    • isSelfCall

      private org.apache.bcel.classfile.Method isSelfCall(org.apache.bcel.generic.InvokeInstruction inv)
      Is the given instruction a self-call?
