DoubleBuffer holds a sequence of double values for use in an I/O operation. Most of the methods of this class are directly analogous to methods defined by ByteBuffer except that they use double and double[ ] argument and return values instead of byte and byte[ ] values. See ByteBuffer for details.

DoubleBuffer is abstract and has no constructor. Create one by calling the static allocate( ) or wrap( ) methods, which are also analogs of ByteBuffer methods. Or, create a "view" DoubleBuffer by calling the asDoubleBuffer( ) method of an underlying ByteBuffer .
