  • Constructor Details

    • GenericSignatureParser

      public GenericSignatureParser(String signature)
      Parses a generic method signature of the form: (argument_signature)return_type_signature
      Parameters:
      signature - the method signature to be parsed

  • Method Details

    • parameterSignatureIterator

      public Iterator<String> parameterSignatureIterator()
      Get an Iterator over signatures of the method parameters.
      Returns:
      Iterator which returns the parameter type signatures in order

    • getReturnTypeSignature

      public String getReturnTypeSignature()
      Get the method return type signature.
      Returns:
      the method return type signature

    • getNumParameters

      public int getNumParameters()
      Get the number of parameters in the signature.
      Returns:
      the number of parameters

    • getNumParametersForInvocation

      public static int getNumParametersForInvocation(org.apache.bcel.generic.InvokeInstruction inv, org.apache.bcel.generic.ConstantPoolGen cpg)

    • getGenericSignatureIterator

      @CheckForNull public static Iterator<String> getGenericSignatureIterator(org.apache.bcel.classfile.Method target)
      Parameters:
      target - the method whose signature is to be parsed
      Returns:
      an iterator over the parameters of the generic signature of method. Returns null if the generic signature cannot be parsed

    • compareSignatures

      public static boolean compareSignatures(String plainSignature, String genericSignature)
      Compare a plain method signature to the a generic method Signature and return true if they match

    • main
