equalDescriptors

public static boolean equalDescriptors(String desc1,
                                       String desc2)

externalizeClass

public static String externalizeClass(String className)

convert a classname from canonical form to the form used to represent it externally i.e. replace all dots with slashes

Parameters:

className -

Returns:

internalizeClass

public static String internalizeClass(String className)

convert a classname from external form to canonical form i.e. replace all slashes with dots

Parameters:

className -

Returns:

externalizeType

public static String externalizeType(String typeName)

convert a type name from canonical form to the form used to represent it externally i.e. replace primitive type names by the appropriate single letter types, class names by the externalized class name bracketed by 'L' and ';' and array names by the base type name preceded by '['.

Parameters:

typeName -

Returns:

externalizeDescriptor

public static String externalizeDescriptor(String desc)

convert a method descriptor from canonical form to the form used to represent it externally

Parameters:

desc - the method descriptor which must be trimmed of any surrounding white space

Returns:

an externalised form for the descriptor

internalizeDescriptor

public static String internalizeDescriptor(String desc)

convert a method descriptor from the form used to represent it externally to canonical form

Parameters:

desc - the method descriptor which must be trimmed of any surrounding white space and start with "(". it must end either with ")" or with ") " followed by an exernalized return type

Returns:

an internalised form for the descriptor, possibly followed by a space and externalized return type

parseMethodName

public static String parseMethodName(String targetMethod)

split off the method name preceding the signature and return it

Parameters:

targetMethod - - the unqualified method name, possibly including signature

Returns:

parseMethodDescriptor

public static String parseMethodDescriptor(String targetMethod)

split off the signature following the method name and return it

Parameters:

targetMethod - - the unqualified method name, possibly including signature

Returns:
