public interface SuspendableReadChannel
extends CloseableChannel

A suspendable readable channel. This type of channel is associated with a listener which can suspend and resume reads as needed.

Method Summary

void	awaitReadable() Block until this channel becomes readable again.
void	awaitReadable(long time, TimeUnit timeUnit) Block until this channel becomes readable again, or until the timeout expires.
ChannelListener.Setter<? extends SuspendableReadChannel>	getCloseSetter() Get the setter which can be used to change the close listener for this channel.
ChannelListener.Setter<? extends SuspendableReadChannel>	getReadSetter() Get the setter which can be used to change the read listener for this channel.
void	resumeReads() Resume reads on this channel.
void	shutdownReads() Places this readable channel at "end of stream".

Method Detail

suspendReads

void suspendReads()

Suspend further read notifications on this channel.

resumeReads

void resumeReads()

Resume reads on this channel. The read listener will be called as soon as there is data available to be read.

shutdownReads

void shutdownReads()
                   throws IOException

Places this readable channel at "end of stream". Further reads will result in EOF. Shutting down all directions of a channel will cause Channel.close() to be called automatically.

Throws:

IOException - if an I/O error occurs

awaitReadable

void awaitReadable()
                   throws IOException

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

Throws:

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

IOException - if an I/O error occurs

Since:

1.2

awaitReadable

void awaitReadable(long time,
                   TimeUnit timeUnit)
                   throws IOException

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

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

Since:

1.2

getReadSetter

ChannelListener.Setter<? extends SuspendableReadChannel> getReadSetter()

Get the setter which can be used to change the read listener for this channel. When the listener is called, additional notifications are automatically suspended.

Returns:

the setter

Since:

2.0

getCloseSetter

ChannelListener.Setter<? extends SuspendableReadChannel> getCloseSetter()

Get the setter which can be used to change the close listener for this channel. If the channel is already closed, then the listener will not be called.

Specified by:

getCloseSetter in interface CloseableChannel

Returns:

the setter
