Constructor Detail

AbstractSourceConduit

protected AbstractSourceConduit(D next)

Construct a new instance.

Parameters:

next - the delegate conduit to set

Method Detail

terminateReads

public void terminateReads()
                    throws IOException

Description copied from interface: SourceConduit

Indicate that no more data will be read from this conduit. If unread data exists, an exception may be thrown.

Specified by:

terminateReads in interface SourceConduit

Throws:

IOException - if there was a problem

isReadShutdown

public boolean isReadShutdown()

Description copied from interface: SourceConduit

Determine whether reads have been shut down on this conduit.

Specified by:

isReadShutdown in interface SourceConduit

Returns:

true if writes are shut down, false otherwise

resumeReads

public void resumeReads()

Description copied from interface: SourceConduit

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

Specified by:

resumeReads in interface SourceConduit

suspendReads

public void suspendReads()

Description copied from interface: SourceConduit

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

Specified by:

suspendReads in interface SourceConduit

wakeupReads

public void wakeupReads()

Description copied from interface: SourceConduit

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

Specified by:

wakeupReads in interface SourceConduit

isReadResumed

public boolean isReadResumed()

Description copied from interface: SourceConduit

Determine whether read notifications are currently enabled.

Specified by:

isReadResumed in interface SourceConduit

Returns:

true if read notifications are enabled

awaitReadable

public void awaitReadable()
                   throws IOException

Description copied from interface: SourceConduit

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

Specified by:

awaitReadable in interface SourceConduit

Throws:

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

IOException - if an I/O error occurs

awaitReadable

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

Description copied from interface: SourceConduit

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

Specified by:

awaitReadable in interface SourceConduit

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

getReadThread

public XnioIoThread getReadThread()

Description copied from interface: SourceConduit

Get the XNIO read thread.

Specified by:

getReadThread in interface SourceConduit

Returns:

the XNIO read thread

setReadReadyHandler

public void setReadReadyHandler(ReadReadyHandler handler)

Description copied from interface: SourceConduit

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:

setReadReadyHandler in interface SourceConduit
