All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.nio.channels.Channel, java.nio.channels.WritableByteChannel, BlockableChannel, SelectionChannel, BufferProcessor, WritableSelectionChannel

Direct Known Subclasses:

WritableSslChannel

@Deprecated
public class WritableBufferedChannel
extends BufferedSelectionChannel<WritableSelectionChannel>
implements WritableSelectionChannel

Deprecated.

Will be removed to favor lower-level network extensions allowing more control at the Restlet API level.

Writable byte channel based on a target socket channel. It is capable of first filling a buffer before draining it to the target channel.

Constructor Detail

WritableBufferedChannel

public WritableBufferedChannel(Buffer buffer,
                               WritableSelectionChannel target,
                               WakeupListener wakeupListener)

Deprecated.

Constructor.

Parameters:

buffer - The source byte buffer, typically remaining from previous read processing.

target - The target channel.

wakeupListener - The wakeup listener that will be notified.

Method Detail

couldDrain

public boolean couldDrain(Buffer buffer,
                          java.lang.Object... args)

Deprecated.

Indicates if the buffer could be drained again.

Parameters:

buffer - The IO buffer to drain.

args - The optional arguments to pass back to the callbacks.

Returns:

True if the buffer could be drained again.

couldFill

public boolean couldFill(Buffer buffer,
                         java.lang.Object... args)

Deprecated.

Indicates if the buffer could be filled again.

Specified by:

couldFill in interface BufferProcessor

Parameters:

buffer - The IO buffer to fill.

args - The optional arguments to pass back to the callbacks.

Returns:

True if the buffer could be filled again.

onDrain

public final int onDrain(Buffer buffer,
                         int maxDrained,
                         java.lang.Object... args)
                  throws java.io.IOException

Deprecated.

Drains the byte buffer.

Specified by:

onDrain in interface BufferProcessor

Parameters:

buffer - The IO buffer to drain.

maxDrained - The maximum number of bytes drained by this call.

args - The optional arguments to pass back to the callbacks.

Returns:

The number of bytes drained.

Throws:

java.io.IOException

onFill

public int onFill(Buffer buffer,
                  java.lang.Object... args)
           throws java.io.IOException

Deprecated.

Fills the byte buffer by writing the current message.

Specified by:

onFill in interface BufferProcessor

Parameters:

buffer - The IO buffer to drain.

args - The optional arguments to pass back to the callbacks.

Returns:

The number of bytes filled.

Throws:

java.io.IOException

write

public int write(java.nio.ByteBuffer sourceBuffer)
          throws java.io.IOException

Deprecated.

Reads some bytes and put them into the destination buffer. The bytes come from the underlying channel.

Specified by:

write in interface java.nio.channels.WritableByteChannel

Parameters:

sourceBuffer - The source buffer.

Returns:

The number of bytes written, possibly 0.

Throws:

java.io.IOException
