Constructor Detail

GenericSignatureParser

public GenericSignatureParser(java.lang.String signature)

Parses a generic method signature of the form: (argument_signature)return_type_signature

Parameters:

signature - the method signature to be parsed

Method Detail

parameterSignatureIterator

public java.util.Iterator<java.lang.String> parameterSignatureIterator()

Get an Iterator over signatures of the method parameters.

Returns:

Iterator which returns the parameter type signatures in order

getReturnTypeSignature

public java.lang.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)

Get the number of parameters passed to method invocation.

Parameters:

inv -

cpg -

Returns:

int number of parameters

getGenericSignatureIterator

@CheckForNull
public static java.util.Iterator<java.lang.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(java.lang.String plainSignature,
                        java.lang.String genericSignature)

Compare a plain method signature to the a generic method Signature and return true if they match

main

public static void main(java.lang.String[] args)
