MTByteBuffer

Inherits from: MTBuffer

An MTByteBuffer is a thread-safe, flow-controlled, fixed-size byte buffer. In other words, it is a concrete subclass of MTBuffer where each abstract frame is one byte. It is intended to be used as a producer/consumer conduit for arbitrary, byte-oriented data where each of producer and consumer may be batch-oriented or time-constrained.

Instance Methods

capacity

- (unsigned) capacity

Returns the number of bytes the receiver can hold.

count

- (unsigned) count

Returns the number of bytes currently stored in the receiver.

flush

- (void) flush

Empties the receiver.

initWithCapacity:

- (id) initWithCapacity:(unsigned)capacity

Initializes a newly allocated buffer with space for capacity bytes. This is the designated initializer.

readToBytes:count:waitForData:

- (unsigned) readToBytes:(void *)theBytes count:(unsigned)count waitForData:(Boolean)wait

Copies up to count bytes from the receiver into theBytes. If wait is NO, then a maximum of [receiver count] bytes will be copied immediately. If wait is YES and the receiver has not been closed, then exactly count bytes will be copied, and this method will pause if necessary until enough data has been written into the buffer by writeFromBytes:count:waitForRoom: to supply the request. Returns the number of bytes copied.

writeFromBytes:count:waitForRoom:

- (unsigned) writeFromBytes:(void *)theBytes count:(unsigned)count waitForRoom:(Boolean)wait

Copies up to count bytes from theBytes into the receiver. If wait is NO, then a maximum of capacity minus [receiver count] bytes will be copied immediately. If wait is YES and the receiver has not been closed, then exactly count bytes will be copied, and this method will pause if necessary until enough room has been made in the buffer by readToBytes:count:waitForData: to accommodate the request. Returns the number of bytes copied.
