Remarks

Compacts this buffer&nbsp;&nbsp;(optional operation).

The doubles between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the double at index p&nbsp;=&nbsp;position() is copied to index zero, the double at index p&nbsp;+&nbsp;1 is copied to index one, and so forth until the double at index limit()&nbsp;-&nbsp;1 is copied to index n&nbsp;=&nbsp;limit()&nbsp;-&nbsp;1&nbsp;-&nbsp;p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

The buffer's position is set to the number of doubles copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.
