// The GTMGatherInput stream is an input stream implementation that is to be
|
|
// instantiated with an NSArray of NSData objects. It works in the traditional
|
|
// scatter/gather vector I/O model. Rather than allocating a big NSData object
|
|
// to hold all of the data and performing a copy into that object, the
|
|
// GTMGatherInputStream will maintain a reference to the NSArray and read from
|
|
// each NSData in turn as the read method is called. You should not alter the
|
|
// underlying set of NSData objects until all read operations on this input
|
|
// stream have completed.
