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)
