CFAllocator is an opaque type that allocates and deallocates memory for you. You never have to allocate, reallocate, or deallocate memory directly for Core Foundation objects—and rarely should you. You pass CFAllocator objects into functions that create objects; these functions have “Create” embedded in their names, for example, CFString. The creation functions use the allocators to allocate memory for the objects they create.
func CFAllocatorCreates an allocator object.
func CFAllocatorAllocates memory using the specified allocator.
func CFAllocatorDeallocates a block of memory with a given allocator.
func CFAllocatorObtains the number of bytes likely to be allocated upon a specific request.
func CFAllocatorReallocates memory using the specified allocator.
func CFAllocatorGets the default allocator object for the current thread.
func CFAllocatorSets the given allocator as the default for the current thread.
func CFAllocatorObtains the context of the specified allocator or of the default allocator.
func CFAllocatorReturns the type identifier for the CFAllocator opaque type.
typealias CFAllocatorA prototype for a function callback that allocates memory of a requested size.
typealias CFAllocatorA prototype for a function callback that provides a description of the specified data.
typealias CFAllocatorA prototype for a function callback that deallocates a block of memory.
typealias CFAllocatorA prototype for a function callback that gives the size of memory likely to be allocated, given a certain request.
typealias CFAllocatorA prototype for a function callback that reallocates memory of a requested size for an existing block of memory.
typealias CFAllocatorA prototype for a function callback that releases the given data.
typealias CFAllocatorA prototype for a function callback that retains the given data.
struct CFAllocatorA structure that defines the context or operating environment for an allocator (CFAllocator) object. Every Core Foundation allocator object must have a context defined for it.
class CFAllocatorA reference to a CFAllocator object.
CFAllocator provides the following predefined allocators. In general, you should use k unless one of the special circumstances exist below.
The CFFileDescriptor provides an opaque type to monitor file descriptors for read and write activity via CFRunLoop.
CFStringTokenizer allows you to tokenize strings into words, sentences or paragraphs in a language-neutral way. It supports languages such as Japanese and Chinese that do not delimit words by spaces, as well as de-compounding German compounds. You can obtain Latin transcription for tokens. It also provides language identification API.
