Detailed Description

Utilities for use with key value coding. You could instantiate one of these in your app-startup:

 ERXKeyValueCodingUtilities.registerClass(SomeClass.class); 
 NSKeyValueCodingAdditions statics = ERXKeyValueCodingUtilities.Statics;
 myValue = statics.valueForKeyPath("SomeClass.SOME_FIELD");
 

Also has utilities for getting and private fields and methods on an object.

Member Function Documentation

static Field accessibleFieldForKey	(	Object	target,
		String	key
	)			[static, private]

static Method accessibleMethodForKey	(	Object	target,
		String	key
	)			[static, private]

static Object classValueForKey	(	Class	clazz,
		String	key
	)			[static]

Extends key-value coding to a class. 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

static Field fieldForKey	(	Object	target,
		String	key
	)			[static]

static Method methodForKey	(	Object	target,
		String	key
	)			[static]

static Object privateValueForKey	(	Object	target,
		String	key
	)			[static]

static void registerClass

(

Class

clazz

)

[static]

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

static NSArray<ERXKeyValuePair> staticStringsForClass

(

Class

c

)

[static]

Returns final strings constants from an interface or class. Useful in particular when you want to create selection lists from your interfaces automatically.

Parameters:

c

static void takeChangedValuesFromDictionary	(	Object	object,
		NSDictionary< String,?>	dictionary
	)			[static]

 * Works like takeValuesFromDictionary, except that it only calls takeValueForKey if the current value  * is different than the new value.  *

Parameters:

	object	the object on which to operate
	dictionary	the key-value pairs to set

static void takePrivateValueForKey	(	Object	target,
		Object	value,
		String	key
	)			[static]
