Method Detail

terminateWrites

public void terminateWrites()
                     throws IOException

Description copied from interface: SinkConduit

Signal that no more write data is forthcoming. The conduit must be SinkConduit.flush()ed before it is considered to be shut down.

Specified by:

terminateWrites in interface SinkConduit

Throws:

IOException

isWriteShutdown

public boolean isWriteShutdown()

Description copied from interface: SinkConduit

Determine whether writes have been fully shut down on this conduit.

Specified by:

isWriteShutdown in interface SinkConduit

Returns:

true if writes are fully shut down, false otherwise

resumeWrites

public void resumeWrites()

Description copied from interface: SinkConduit

Indicate that the conduit's WriteReadyHandler should be invoked as soon as data can be written without blocking.

Specified by:

resumeWrites in interface SinkConduit

suspendWrites

public void suspendWrites()

Description copied from interface: SinkConduit

Indicate that calling the conduit's WriteReadyHandler should be suspended.

Specified by:

suspendWrites in interface SinkConduit

wakeupWrites

public void wakeupWrites()

Description copied from interface: SinkConduit

Indicate that the conduit's WriteReadyHandler should be invoked immediately, and then again as soon as data can be written without blocking.

Specified by:

wakeupWrites in interface SinkConduit

isWriteResumed

public boolean isWriteResumed()

Description copied from interface: SinkConduit

Determine whether write notifications are currently enabled.

Specified by:

isWriteResumed in interface SinkConduit

Returns:

true if write notifications are enabled

awaitWritable

public void awaitWritable()
                   throws IOException

Description copied from interface: SinkConduit

Block until this channel becomes writable again. This method may return spuriously before the channel becomes writable.

Specified by:

awaitWritable in interface SinkConduit

Throws:

InterruptedIOException - if the operation is interrupted; the thread's interrupt flag will be set as well

IOException - if an I/O error occurs

awaitWritable

public void awaitWritable(long time,
                          TimeUnit timeUnit)
                   throws IOException

Description copied from interface: SinkConduit

Block until this conduit becomes writable again, or until the timeout expires. This method may return spuriously before the conduit becomes writable or the timeout expires.

Specified by:

awaitWritable in interface SinkConduit

Parameters:

time - the time to wait

timeUnit - the time unit

Throws:

InterruptedIOException - if the operation is interrupted; the thread's interrupt flag will be set as well

IOException - if an I/O error occurs

getWriteThread

public XnioIoThread getWriteThread()

Description copied from interface: SinkConduit

Get the write thread for this conduit.

Specified by:

getWriteThread in interface SinkConduit

Returns:

the thread, or null if none is configured or available

setWriteReadyHandler

public void setWriteReadyHandler(WriteReadyHandler handler)

Description copied from interface: SinkConduit

Set the handler which should receive readiness notifications. A filter may pass this invocation on to the filter it wraps, or it may substitute itself.

Specified by:

setWriteReadyHandler in interface SinkConduit

truncateWrites

public void truncateWrites()
                    throws IOException

Description copied from interface: SinkConduit

Terminate writes and discard any outstanding write data. The conduit is terminated and flushed regardless of the outcome of this method.

Specified by:

truncateWrites in interface SinkConduit

Throws:

IOException - if channel termination failed for some reason

flush

public boolean flush()
              throws IOException

Description copied from interface: SinkConduit

Flush out any unwritten, buffered output.

Specified by:

flush in interface SinkConduit

Returns:

true if everything is flushed, false otherwise

Throws:

IOException - if flush fails
