A double buffer.
This class defines four categories of operations upon double buffers:
Double buffers can be created either by
, which allocates space for the buffer's
double array into a buffer, or by creating a
view of an existing byte buffer.
Like a byte buffer, a double buffer is either direct or non-direct. A
double buffer created via the wrap methods of this class will
be non-direct. A double buffer created as a view of a byte buffer will
be direct if, and only if, the byte buffer itself is direct. Whether or not
a double buffer is direct may be determined by invoking the
Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained.
Public Method Summary

Returns the double array that backs this buffer (optional operation).
Returns the offset within this buffer's backing array of the first element of the buffer (optional operation).
