Modifier and Type	Class and Description
protected class	SelectorKernel.SelectorThread This class is purposely tucked neatly away because messing with the selector from other threads for any reason is very bad.

Constructor Detail

SelectorKernel

public SelectorKernel(java.net.InetAddress host,
                      int port)

SelectorKernel

public SelectorKernel(int port)
               throws java.io.IOException

Throws:

java.io.IOException

SelectorKernel

public SelectorKernel(java.net.InetSocketAddress address)

Method Detail

createSelectorThread

protected SelectorKernel.SelectorThread createSelectorThread()

initialize

public void initialize()

Description copied from interface: Kernel

Initializes the kernel and starts any internal processing.

terminate

public void terminate()
               throws java.lang.InterruptedException

Description copied from interface: Kernel

Gracefully terminates the kernel and stops any internal daemon processing. This method will not return until all internal threads have been shut down.

Throws:

java.lang.InterruptedException

broadcast

public void broadcast(Filter<? super Endpoint> filter,
                      java.nio.ByteBuffer data,
                      boolean reliable,
                      boolean copy)

Description copied from interface: Kernel

Dispatches the data to all endpoints managed by the kernel that match the specified endpoint filter.. If 'copy' is true then the implementation will copy the byte buffer before delivering it to endpoints. This allows the caller to reuse the data buffer. Though it is important that the buffer not be changed by another thread while this call is running. Only the bytes from data.position() to data.remaining() are sent.

addEndpoint

protected NioEndpoint addEndpoint(java.nio.channels.SocketChannel c)

removeEndpoint

protected void removeEndpoint(NioEndpoint p,
                              java.nio.channels.SocketChannel c)

closeEndpoint

protected void closeEndpoint(NioEndpoint p)
                      throws java.io.IOException

Called by the endpoints when they need to be closed.

Throws:

java.io.IOException

wakeupSelector

protected void wakeupSelector()

Used internally by the endpoints to wakeup the selector when they have data to send.

newData

protected void newData(NioEndpoint p,
                       java.nio.channels.SocketChannel c,
                       java.nio.ByteBuffer shared,
                       int size)
