Constructs a channel that reads bytes from the given stream.

  Constructs a channel that reads bytes from the given stream.

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.

Returns: A new readable byte channel
Parameters:
- in - The stream from which bytes are to be read

  Constructs a channel that writes bytes to the given stream.

  Constructs a channel that writes bytes to the given stream.

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.

Returns: A new writable byte channel
Parameters:
- out - The stream to which bytes are to be written

  Constructs a stream that reads bytes from the given channel.

  Constructs a stream that reads bytes from the given channel.

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.

Returns: A new input stream
Parameters:
- ch - The channel from which bytes will be read

  Constructs a stream that writes bytes to the given channel.

  Constructs a stream that writes bytes to the given channel.

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.

Returns: A new output stream
Parameters:
- ch - The channel to which bytes will be written

  Constructs a reader that decodes bytes from the given channel using the given decoder.

  Constructs a reader that decodes bytes from the given channel using the given decoder.

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.

Returns: A new reader
Parameters:
- ch - The channel from which bytes will be read
- dec - The charset decoder to be used
- minBufferCap - The minimum capacity of the internal byte buffer, or -1 if an implementation-dependent default capacity is to be used

  Constructs a reader that decodes bytes from the given channel according to the named charset.

  Constructs a reader that decodes bytes from the given channel according to the named charset.

An invocation of this method of the form

 Channels.newReader(ch, csname)

behaves in exactly the same way as the expression

 Channels.newReader(ch,
                    Charset.forName(csName)
                        .newDecoder(),
                    -1);

Returns: A new reader
Parameters:
- ch - The channel from which bytes will be read
- csName - The name of the charset to be used
Throws:
- UnsupportedCharsetException - If no support for the named charset is available in this instance of the Java virtual machine

  Constructs a writer that encodes characters using the given encoder and writes the resulting bytes to the given channel.

The resulting stream will not otherwise be buffered. Closing the stream will in turn cause the channel to be closed.

Returns: A new writer
Parameters:
- ch - The channel to which bytes will be written
- enc - The charset encoder to be used
- minBufferCap - The minimum capacity of the internal byte buffer, or -1 if an implementation-dependent default capacity is to be used
