| ScatteringByteChannel | java.nio.channels |
This interface extends
ReadableByteChannel and adds two additional
read( ) methods that read bytes for a channel and
"scatter" them to an array (or
subarray) of buffers. These methods are passed an array of
ByteBuffer objects, and, optionally, an offset and
length that define the region of the array to be used. The
read( ) method attempts to read enough bytes from
the channel to fill each of the specified buffers in the order in
which they appear in the buffer array (the
"scattering" process is actually
much more orderly and linear than the name implies). The return value
of the method is the number of bytes actually read, which may be
different than the sum of the remaining bytes in the buffers. See
ReadableByteChannel for a discussion of exceptions
and thread-safety that apply to these read( )
methods as well.
