- oneByte
- the byte to push back to this stream.
Type Reason Java.IO.IOException if this stream is closed or the internal pushback buffer is full.
Pushes the specified byte oneByte back to this stream. Only the least significant byte of the integer oneByte is pushed back. This is done in such a way that the next byte read from this stream is (byte) oneByte.
If this stream's internal pushback buffer cannot store the byte, an IOException is thrown.
