Interface Swift_OutputByteStream
| Implemented by | Swift_ByteStream_ArrayByteStream, Swift_FileStream, Swift_Transport_IoBuffer |
|---|
An abstract means of reading data.
Classes implementing this interface may use a subsystem which requires less memory than working with large strings of data.
Public Methods
| Method | Description | Defined By |
|---|---|---|
| read() | Reads $length bytes from the stream into a string and moves the pointer through the stream by $length. | Swift_OutputByteStream |
| setReadPointer() | Move the internal read pointer to $byteOffset in the stream. | Swift_OutputByteStream |
Method Details
Reads $length bytes from the stream into a string and moves the pointer through the stream by $length.
If less bytes exist than are requested the remaining bytes are given instead. If no bytes are remaining at all, boolean false is returned.
