 the peek position. The current read position is left
 unchanged.

 <p>This method blocks until at least one byte of data can be peeked, the end of the input is
 detected, or an exception is thrown.

 <p>Calling <a href="ExtractorInput.html#resetPeekPosition()"><code>ExtractorInput.resetPeekPosition()</code></a> resets the peek position to equal the current read
 position, so the caller can peek the same data again. Reading or skipping also resets the peek
 position.</div>
