public static InputStream newInputStream(ReadableByteChannel ch)
The read methods of the resulting stream will throw an
IllegalBlockingModeException if invoked while the underlying
channel is in non-blocking mode. The stream will not be buffered, and
it will not support the mark or reset methods. The stream will be safe for access by
multiple concurrent threads. Closing the stream will in turn cause the
channel to be closed.
ch - The channel from which bytes will be readpublic static OutputStream newOutputStream(WritableByteChannel ch)
The write methods of the resulting stream will throw an
IllegalBlockingModeException if invoked while the underlying
channel is in non-blocking mode. The stream will not be buffered. The
stream will be safe for access by multiple concurrent threads. Closing
the stream will in turn cause the channel to be closed.

The stream will not be buffered, and it will not support the mark or reset methods. The
stream will be safe for access by multiple concurrent threads. Closing
the stream will in turn cause the channel to be closed.

ch - The channel to which bytes will be writtenpublic static ReadableByteChannel newChannel(InputStream in)
The resulting channel will not be buffered; it will simply redirect its I/O operations to the given stream. Closing the channel will in turn cause the stream to be closed.
in - The stream from which bytes are to be readpublic static WritableByteChannel newChannel(OutputStream out)
The resulting channel will not be buffered; it will simply redirect its I/O operations to the given stream. Closing the channel will in turn cause the stream to be closed.
out - The stream to which bytes are to be writtenpublic static Reader newReader(ReadableByteChannel ch, CharsetDecoder dec, int minBufferCap)
The resulting stream will contain an internal input buffer of at
least minBufferCap bytes. The stream's read methods
will, as needed, fill the buffer by reading bytes from the underlying
channel; if the channel is in non-blocking mode when bytes are to be
read then an IllegalBlockingModeException will be thrown. The
resulting stream will not otherwise be buffered, and it will not support
the mark or reset methods.
Closing the stream will in turn cause the channel to be closed.

The resulting stream will contain an internal output buffer of at
least minBufferCap bytes. The stream's write methods
will, as needed, flush the buffer by writing bytes to the underlying
channel; if the channel is in non-blocking mode when bytes are to be
written then an IllegalBlockingModeException will be thrown.
The resulting stream will not otherwise be buffered. Closing the stream
will in turn cause the channel to be closed.
