public java.lang.Object invokeCustom(java.lang.Object proxy,
                                     java.lang.reflect.Method method,

Specified by:

Parameters:

proxy - the proxy

method - the method

args - the arguments

Returns:

the result of the invocation of the delegate

Throws:

toString

public java.lang.String toString()

Description copied from class: ConversionHandler

Returns a String version of the delegate.

Overrides:

toString in class ConversionHandler

Object.toString()

checkMethod

protected boolean checkMethod(java.lang.reflect.Method method)

Overrides:

checkMethod in class ConversionHandler

isCoreObjectMethod

public static boolean isCoreObjectMethod(java.lang.reflect.Method method)

Checks whether a method is a core method from java.lang.Object. Such methods often receive special treatment because they are deemed fundamental enough to not be tampered with. call toString() is an exception to allow overriding toString() by a closure specified in the map

Parameters:

method - the method to check

Returns:

true if the method is deemed to be a core method
