Declared in: Foundation/NSProxy.h
Availability: OpenStep
The NSProxy class provides a basic implementation of a
class whose instances are used to stand in
for other objects. real
object represented by the proxy. You must subclass
NSProxy to implement
-forwardInvocation:
to these real objects.
Note that NSProxy is a different sort of
class than others in the GNUstep Base library in that
it is the only example of a root class besides
NSObject
. Thus, it implements the NSObject
protocol but is not a subclass of NSObject.
Instance Variables
+ (id)
alloc ;
Availability: OpenStep
Allocates and returns an NSProxy instance in the
default zone.
+ (id)
allocWithZone: (
NSZone *)z;
Availability: OpenStep
Allocates and returns an NSProxy instance in the
specified zone z .
+ (id)
autorelease ;
Availability: OpenStep
Returns the receiver.
+ (Class)
class ;
Availability: OpenStep
Returns the receiver.
+ (
NSString *)
description ;
Availability: OpenStep
Returns a string describing the receiver.
+ (BOOL)
isKindOfClass: (Class)aClass;
Availability: OpenStep
Returns NO... the NSProxy class cannot
be an instance of any class.
+ (BOOL)
isMemberOfClass: (Class)aClass;
Availability: OpenStep
Returns YES if aClass is
identical to the receiver, NO
otherwise.
+ (void)
load ;
Availability: OpenStep
An empty method provided for subclasses to override.
+ (oneway void)
release ;
Availability: OpenStep
An empty method provided for subclasses to override.
+ (BOOL)
respondsToSelector: (SEL)aSelector;
Availability: OpenStep
Returns YES if the receiver responds
to aSelector , NO otherwise.
+ (id)
retain ;
Availability: OpenStep
Returns the receiver.
+ (
NSUInteger )
retainCount ;
Availability: OpenStep
Returns the maximum unsigned
integer value.
- (id)
autorelease ;
Availability: OpenStep
Adds the receiver to the current autorelease pool and
returns self.
- (Class)
class ;
Availability: OpenStep
Returns the class of the receiver.
- (BOOL)
conformsToProtocol: (Protocol*)aProtocol;
Availability: OpenStep
Calls the
-forwardInvocation:
method to determine if the 'real' object referred to
by the proxy conforms to
aProtocol . Returns
the result.
NB. The default operation of
-forwardInvocation:
is to raise an exception.
- (void)
dealloc ;
Availability: OpenStep
Frees the memory used by the receiver.
- (
NSString *)
description ;
Availability: OpenStep
Returns a text description of the receiver.
- (void)
forwardInvocation: (
NSInvocation *)anInvocation;
Availability: OpenStep
Subclasses
must override this method.
Raises an NSInvalidArgumentException.
- (
NSUInteger )
hash ;
Availability: OpenStep
Returns the address of the receiver... so it can be
stored in a dictionary.
- (id)
init ;
Availability: OpenStep
This is a designated initialiser for the class.
Subclasses
must override this method.
Initialises the receiver and returns the
resulting instance.
- (BOOL)
isEqual: (id)anObject;
Availability: OpenStep
Tests for pointer equality with anObject .
- (BOOL)
isKindOfClass: (Class)aClass;
Availability: OpenStep
Calls the
-forwardInvocation:
method to determine if the 'real' object referred to
by the proxy is an instance of the specified class.
Returns the result.
NB. The default
operation of
-forwardInvocation:
is to raise an exception.
- (BOOL)
isMemberOfClass: (Class)aClass;
Availability: OpenStep
Calls the
-forwardInvocation:
method to determine if the 'real' object referred to
by the proxy is an instance of the specified class.
Returns the result.
NB. The default
operation of
-forwardInvocation:
is to raise an exception.
- (BOOL)
isProxy ;
Availability: OpenStep
Returns YES.
- (
NSMethodSignature *)
methodSignatureForSelector: (SEL)aSelector;
Availability: OpenStep
If we respond to the method directly, create and return
a method signature. Otherwise raise an exception.
- (oneway void)
release ;
Availability: OpenStep
Decrement the retain count for the receiver...
deallocate if it would become negative.
- (BOOL)
respondsToSelector: (SEL)aSelector;
Availability: OpenStep
If we respond to the method directly, return
YES, otherwise forward this request to
the object we are acting as a proxy for.
- (id)
retain ;
Availability: OpenStep
Increment the retain count for the receiver.
- (
NSUInteger )
retainCount ;
Availability: OpenStep
Return the retain count for the receiver.
- (id)
self ;
Availability: OpenStep
Returns the receiver.
- (Class)
superclass ;
Availability: OpenStep
Returns the superclass of the receiver's class.
- (
NSZone *)
zone ;
Availability: OpenStep
Returns the zone in which the receiver was
allocated.
