public interface StreamSourceChannel
extends ReadableByteChannel, ScatteringByteChannel, SuspendableReadChannel

A stream source channel. This type of channel is a readable source for bytes.

Method Summary

ChannelListener.Setter<? extends StreamSourceChannel>	getCloseSetter() Get the setter which can be used to change the close listener for this channel.
ChannelListener.Setter<? extends StreamSourceChannel>	getReadSetter() Get the setter which can be used to change the read listener for this channel.
long	transferTo(long position, long count, FileChannel target) Transfers bytes into the given file from this channel.

Method Detail

transferTo

long transferTo(long position,
                long count,
                FileChannel target)
                throws IOException

Transfers bytes into the given file from this channel. Using this method in preference to FileChannel.transferFrom(java.nio.channels.ReadableByteChannel, long, long) may provide a performance advantage on some platforms.

Parameters:

position - the position within the file from which the transfer is to begin

count - the number of bytes to be transferred

target - the file to write to

Returns:

the number of bytes (possibly 0) that were actually transferred

Throws:

IOException - if an I/O error occurs

getReadSetter

ChannelListener.Setter<? extends StreamSourceChannel> 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.

Specified by:

getReadSetter in interface SuspendableReadChannel

Returns:

the setter

getCloseSetter

ChannelListener.Setter<? extends StreamSourceChannel> 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

Specified by:

getCloseSetter in interface SuspendableReadChannel

Returns:

the setter
