Class NSPointerArray

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSFastEnumeration, NSSecureCoding, NSObject
    public class NSPointerArray
extends NSObject
implements NSFastEnumeration, NSCopying, NSSecureCoding
    NSPointerArray.h A PointerArray acts like a traditional array that slides elements on insertion or deletion. Unlike traditional arrays, it holds NULLs, which can be inserted or extracted (and contribute to count). Also unlike traditional arrays, the 'count' of the array may be set directly. Using NSPointerFunctionsWeakMemory object references will turn to NULL on last release. The copying and archiving protocols are applicable only when NSPointerArray is configured for Object uses. The fast enumeration protocol (supporting the for..in statement) will yield NULLs if present. It is defined for all types of pointers although the language syntax doesn't directly support this.

        public boolean _supportsSecureCoding()
        Description copied from interface: NSSecureCoding
        This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.
