Method Summary

void	bind_toObject_withKeyPath_options(NSString binding, ObjCObject observable, NSString keyPath, NSDictionary options) Bindings are considered to be a property of the object which is bound (the object the following two methods are sent to) and all information related to bindings should be retained by the object; all standard bindings on AppKit objects (views, cells, table columns, controllers) unbind their bindings automatically when they are released, but if you create key-value bindings for other kind of objects, you need to make sure that you remove those bindings when you release them (observed objects don't retain their observers, so controllers/model objects might continue referencing and messaging the objects that was bound to them).
NSArray	exposedBindings() for a new key exposed through this method, the default implementation simply falls back to key-value coding Original signature : -(NSArray*)exposedBindings from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:30
NSDictionary	infoForBinding(NSString binding) Returns a dictionary with information about a binding or nil if the binding is not bound (this is mostly for use by subclasses which want to analyze the existing bindings of an object) - the dictionary contains three key/value pairs: NSObservedObjectKey: object bound, NSObservedKeyPathKey: key path bound, NSOptionsKey: dictionary with the options and their values for the bindings.
NSArray	optionDescriptionsForBinding(NSString aBinding) Original signature : -(NSArray*)optionDescriptionsForBinding:(NSString*) from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:54
void	unbind(NSString binding) Original signature : -(void)unbind:(NSString*) from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:36
ObjCClass	valueClassForBinding(NSString binding) optional - mostly for matching transformers Original signature : -(Class)valueClassForBinding:(NSString*) from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:31

exposedBindings

NSArray exposedBindings()

for a new key exposed through this method, the default implementation simply falls back to key-value coding
Original signature : -(NSArray*)exposedBindings
from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:30

valueClassForBinding

ObjCClass valueClassForBinding(NSString binding)

optional - mostly for matching transformers
Original signature : -(Class)valueClassForBinding:(NSString*)
from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:31

bind_toObject_withKeyPath_options

void bind_toObject_withKeyPath_options(NSString binding,
                                       ObjCObject observable,
                                       NSString keyPath,
                                       NSDictionary options)

placeholders and value transformers are specified in options dictionary
Original signature : -(void)bind:(NSString*) toObject:(id) withKeyPath:(NSString*) options:(NSDictionary*)
from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:35

unbind

void unbind(NSString binding)

Original signature : -(void)unbind:(NSString*)
from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:36

infoForBinding

NSDictionary infoForBinding(NSString binding)

Returns a dictionary with information about a binding or nil if the binding is not bound (this is mostly for use by subclasses which want to analyze the existing bindings of an object) - the dictionary contains three key/value pairs: NSObservedObjectKey: object bound, NSObservedKeyPathKey: key path bound, NSOptionsKey: dictionary with the options and their values for the bindings.

Original signature : -(NSArray*)optionDescriptionsForBinding:(NSString*)
from NSKeyValueBindingCreation native declaration : NSKeyValueBinding.h:54
