Class ERXKeyValueCodingUtilities

java.lang.Object
  er.extensions.ERXKeyValueCodingUtilities

public class ERXKeyValueCodingUtilities

extends Object

Utilities for use with key value coding. You could instantiate one of these in your app-startup: public NSKeyValueCodingUtilities statics = ERXKeyValueCodingUtilities.Statics; ERXKeyValueCodingUtilities.registerClass(SomeClass.class); myValue = valueForKeyPath("statics.SomeClass.SOME_FIELD");

public ERXKeyValueCodingUtilities()

Method Detail

registerClass

public static void registerClass(Class clazz)

Registers the class in the KVC resolving system, so you can use valueForKeyPath("MyClass.SOME_KEY"). Inner classes are registered with a "$", i.e. MyClass$InnerClass

Parameters:

clazz -

classValueForKey

public static Object classValueForKey(Class clazz,
                                      String key)

Extends key-value coding to a class. You can currently only get the static fields of the class, not method results. Java arrays and collections are morphed into NSArrays. The implementation is pretty slow, but I didn't exactly want to re-implement all of NSKeyValueCoding here.

Parameters:

clazz -

key -

Returns:
