                                       String keyPath)

If object is an NSKeyValueCodingAdditions, invokes takeValueForKeyPath on object; otherwise invokes NSKeyValueCodingAdditions.DefaultImplementation's takeValueForKeyPath method with object as the object on which to operate.

Parameters:

object - the object on which to operate

value - object's property identified by keypath is set to this

keyPath - identifies the property of an object

public static Object valueForKeyPath(Object object,
                                     String keyPath)

If object is an NSKeyValueCodingAdditions, invokes valueForKeyPath on object; otherwise invokes NSKeyValueCodingAdditions.DefaultImplementation's valueForKeyPath method with object as the object on which to operate.

Parameters:

object - the object on which to operate
