Method summary

hashTableWithOptions: 

+ (instancetype) hashTableWithOptions: (NSPointerFunctionsOptions)options;
Availability: OpenStep

Description forthcoming.

weakObjectsHashTable 

+ (instancetype) weakObjectsHashTable;
Availability: OpenStep

Creates a hash table that uses weak references (using the automatic reference counting mechanism) so that objects are removed when their last other reference disappears.

addObject: 

- (void) addObject: (id)object;
Availability: OpenStep

Adds the object to the receiver.
Adding a nil object has no effect.

allObjects 

- (NSArray*) allObjects;
Availability: OpenStep

Returns an array containing all objects in the receiver.

anyObject 

- (id) anyObject;
Availability: OpenStep

Returns any objct from the receiver, or nil if the receiver contains no objects.

containsObject: 

- (BOOL) containsObject: (id)anObject;
Availability: OpenStep

Returns YES if the receiver contains an item equal to anObject, or NO otherwise.

count 

- (NSUInteger) count;
Availability: OpenStep

Return the number of items atored in the receiver.

initWithOptions: capacity: 

- (instancetype) initWithOptions: (NSPointerFunctionsOptions)options capacity: (NSUInteger)initialCapacity;
Availability: OpenStep

Description forthcoming.

initWithPointerFunctions: capacity: 

- (instancetype) initWithPointerFunctions: (NSPointerFunctions*)functions capacity: (NSUInteger)initialCapacity;
Availability: OpenStep

Description forthcoming.

intersectHashTable: 

- (void) intersectHashTable: (NSHashTable*)other;
Availability: OpenStep

Removes from the receiver any items which are not also present in 'other'.

intersectsHashTable: 

- (BOOL) intersectsHashTable: (NSHashTable*)other;
Availability: OpenStep

Returns YES if the receiver and 'other' contain any items in common.

isEqualToHashTable: 

- (BOOL) isEqualToHashTable: (NSHashTable*)other;
Availability: OpenStep

Returns YES if the receiver and 'other' contain equal sets of items.

isSubsetOfHashTable: 

- (BOOL) isSubsetOfHashTable: (NSHashTable*)other;
Availability: OpenStep

Returns YES fi all the items in the receiver are also present in 'other'

member: 

- (id) member: (id)object;
Availability: OpenStep

Returns an item stored in the receiver which is equal to the supplied object argument, or nil if no matchi is found.

minusHashTable: 

- (void) minusHashTable: (NSHashTable*)other;
Availability: OpenStep

Removes from the receivr all those items which are prsent in both the receiver and in 'other'.

objectEnumerator 

- (NSEnumerator*) objectEnumerator;
Availability: OpenStep

Return an enumerator for the receiver.

pointerFunctions 

- (NSPointerFunctions*) pointerFunctions;
Availability: OpenStep

Return an NSPointerFunctions value describing the functions used by the receiver to handle its contents.

removeAllObjects 

- (void) removeAllObjects;
Availability: OpenStep

Removes all objects.

removeObject: 

- (void) removeObject: (id)object;
Availability: OpenStep

Remove the object (or any equal object) from the receiver.

setRepresentation 

- (NSSet*) setRepresentation;
Availability: OpenStep

Returns a set containing all the objects in the receiver.

unionHashTable: 

- (void) unionHashTable: (NSHashTable*)other;
Availability: OpenStep

Adds to the receiver thse items present in 'other' which were not present in the receiver.
