Constructor Detail

DatagramSocketIO

public DatagramSocketIO(java.nio.channels.DatagramChannel socketChannel,
                        java.lang.String mode)

Construct a DatagramSocketIO for the given DatagramChannel.

Parameters:

socketChannel - a DatagramChannel to wrap

mode - a raw io socket mode String

Method Detail

readinto

public int readinto(java.nio.ByteBuffer buf)

Description copied from class: RawIOBase

Read up to buf.remaining() bytes into buf. Returns number of bytes read (0 for EOF).

Overrides:

readinto in class RawIOBase

Parameters:

buf - a ByteBuffer to read bytes into

Returns:

the amount of data read as an int

readinto

public long readinto(java.nio.ByteBuffer[] bufs)

Read bytes into each of the specified ByteBuffers via scatter i/o.

Overrides:

readinto in class RawIOBase

Parameters:

bufs - an array of ByteBuffers to read bytes into

Returns:

the amount of data read as a long

write

public int write(java.nio.ByteBuffer buf)

Description copied from class: RawIOBase

Write the given ByteBuffer to the IO stream. Returns the number of bytes written, which may be less than buf.remaining().

Overrides:

write in class RawIOBase

Parameters:

buf - a ByteBuffer value

Returns:

the number of bytes written as an int

write

public long write(java.nio.ByteBuffer[] bufs)

Writes bytes from each of the specified ByteBuffers via gather i/o.

Overrides:

write in class RawIOBase

Parameters:

bufs - an array of ByteBuffers

Returns:

the number of bytes written as a long
