java.nio.channels.spi .AbstractSelectableChannel

All known Subclasses:   java.nio.channels .SocketChannel,  java.nio.channels .DatagramChannel,  java.nio.channels .ServerSocketChannel,
AbstractSelectableChannel
abstract public class AbstractSelectableChannel extends SelectableChannel (Code)
Abstract class for selectable channels.
In this class, there are methods about registering/deregistering a channel, about channel closing. It realize the multi-thread safe.

Field Summary
boolean isBlocking


Constructor Summary
protected AbstractSelectableChannel(SelectorProvider selectorProvider)
     Constructor for this class.

Method Summary
final public Object blockingLock()

final public SelectableChannel configureBlocking(boolean blockingMode)
     Set the blocking mode of this channel.
synchronized void deregister(SelectionKey k)

final protected synchronized void implCloseChannel()
     Implement the closing function.
abstract protected void implCloseSelectableChannel()
     Implement the closing function of the SelectableChannel.
abstract protected void implConfigureBlocking(boolean blockingMode)
     Implement the setting of blocking mode.
final public boolean isBlocking()

final public synchronized boolean isRegistered()

final public synchronized SelectionKey keyFor(Selector selector)

final public SelectorProvider provider()
     Answer the SelectorProvider of this channel.
final public SelectionKey register(Selector selector, int interestSet, Object attachment)
     Realize the register function.
It registers current channel to the selector, then answer the selection key.

Field Detail
isBlocking
boolean isBlocking(Code)

Constructor Detail
AbstractSelectableChannel
protected AbstractSelectableChannel(SelectorProvider selectorProvider)(Code)
Constructor for this class.
Parameters:
  selectorProvider - A instance of SelectorProvider

Method Detail
blockingLock
final public Object blockingLock()(Code)

See Also:   java.nio.channels.SelectableChannel.blockingLock

configureBlocking
final public SelectableChannel configureBlocking(boolean blockingMode) throws IOException(Code)
Set the blocking mode of this channel.
See Also:   java.nio.channels.SelectableChannel.configureBlocking(boolean)
Parameters:
  blockingMode - true for blocking mode; falsefor non-blocking mode.

deregister
synchronized void deregister(SelectionKey k)(Code)

implCloseChannel
final protected synchronized void implCloseChannel() throws IOException(Code)
Implement the closing function.
See Also:   java.nio.channels.spi.AbstractInterruptibleChannel.implCloseChannel

implCloseSelectableChannel
abstract protected void implCloseSelectableChannel() throws IOException(Code)
Implement the closing function of the SelectableChannel.
throws:
  IOException - If some I/O exception occurred.

implConfigureBlocking
abstract protected void implConfigureBlocking(boolean blockingMode) throws IOException(Code)
Implement the setting of blocking mode.
Parameters:
  blockingMode - true for blocking mode; falsefor non-blocking mode.
throws:
  IOException - If some I/O exception occurred.

isBlocking
final public boolean isBlocking()(Code)

See Also:   java.nio.channels.SelectableChannel.isBlocking

isRegistered
final public synchronized boolean isRegistered()(Code)

See Also:   java.nio.channels.SelectableChannel.isRegistered

keyFor
final public synchronized SelectionKey keyFor(Selector selector)(Code)

See Also:   java.nio.channels.SelectableChannel.keyFor(java.nio.channels.Selector)

provider
final public SelectorProvider provider()(Code)
Answer the SelectorProvider of this channel.
See Also:   java.nio.channels.SelectableChannel.provider The provider of this channel.

register
final public SelectionKey register(Selector selector, int interestSet, Object attachment) throws ClosedChannelException(Code)
Realize the register function.
It registers current channel to the selector, then answer the selection key. The channel must be open and the interest op set must be valid. If the current channel is already registered to the selector, the method only set the new interest op set; otherwise it will call the register in selector, and add the relative key to the key set of the current channel.
