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.
