| GatheringByteChannel | java.nio.channels |
This
interface
extends WritableByteChannel and adds two
additional write( ) methods that can
"gather" bytes from one or more
buffers and write them out to the channel. These methods are passed
an array of ByteBuffer objects, and, optionally,
an offset and length that define the relevant sub-array to be used.
The write( ) method attempts to write all the
remaining bytes from all the specified buffers (in the order in which
they appear in the buffer array) to the channel. The return value of
the method is the number of bytes actually written. See
WritableByteChannel for a discussion of exceptions
and thread-safety that apply to these write( )
methods as well.
