Interface BufferProcessor

All Known Implementing Classes:

BufferedSelectionChannel, ChannelInputStream, ClientInboundWay, ClientOutboundWay, HttpClientInboundWay, HttpClientOutboundWay, HttpsClientInboundWay, HttpsClientOutboundWay, HttpServerInboundWay, HttpServerOutboundWay, HttpsServerInboundWay, HttpsServerOutboundWay, InboundWay, OutboundWay, ReadableBufferedChannel, ReadableChunkedChannel, ReadableSizedSelectionChannel, ReadableSslChannel, ServerInboundWay, ServerOutboundWay, Way, WritableBufferedChannel, WritableSslChannel

@Deprecated
public interface BufferProcessor

Deprecated.

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

Interface called back when IO buffer draining or filling can actually be done.

Modifier and Type	Method	Description
boolean	canLoop(Buffer buffer, java.lang.Object... args)	Deprecated. Indicates if the processing loop can continue.
boolean	couldFill(Buffer buffer, java.lang.Object... args)	Deprecated. Indicates if the buffer could be filled again.
int	onDrain(Buffer buffer, int maxDrained, java.lang.Object... args)	Deprecated. Drains the byte buffer.
int	onFill(Buffer buffer, java.lang.Object... args)	Deprecated. Fills the byte buffer.
void	onFillEof()	Deprecated. Called back when a fill operation returns with an EOF status.
void	postProcess(int drained)	Deprecated. Called back after a complete processing pass.
int	preProcess(int maxDrained, java.lang.Object... args)	Deprecated. Called back before a processing pass.

Method Detail

canLoop

boolean canLoop(Buffer buffer,
                java.lang.Object... args)

Deprecated.

Indicates if the processing loop can continue.

Parameters:

buffer - The IO buffer to drain.

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

Returns:

True if the processing loop can continue.

couldFill

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

Deprecated.

Indicates if the buffer could be filled again.

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

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

Deprecated.

Drains the byte buffer.

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

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

Deprecated.

Fills the byte buffer.

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

onFillEof

void onFillEof()

Deprecated.

Called back when a fill operation returns with an EOF status.

postProcess

void postProcess(int drained)
          throws java.io.IOException

Deprecated.

Called back after a complete processing pass.

Parameters:

drained - The number of bytes drained or -1 if the filling source has ended.

Throws:

java.io.IOException

preProcess

int preProcess(int maxDrained,
               java.lang.Object... args)
        throws java.io.IOException

Deprecated.

Called back before a processing pass.

Parameters:

maxDrained - The maximum number of bytes drained by this call or 0 for unlimited length.

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

Returns:

The number of bytes drained or -1 if the filling source has ended.

Throws:

java.io.IOException
