LongBuffer holds a sequence of long 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 long and long[ ] argument and return values instead of byte and byte[ ] values. See ByteBuffer for details.

LongBuffer 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" LongBuffer by calling the asLongBuffer( ) method of an underlying ByteBuffer.
