public DriverImpl()
           throws IOException

Throws:

IOException

Method Detail

wakeup

public void wakeup()

Description copied from interface: Driver

Force Driver.doWait(long) to return. If the driver is not currently waiting then the next invocation of Driver.doWait(long) will return immediately unless the Driver.connector() method is invoked in the meantime. Thread-safe.

Specified by:

wakeup in interface Driver

doWait

public boolean doWait(long timeout)

Description copied from interface: Driver

Wait for an active connector or listener, or for Driver.wakeup() to be called. Thread-safe.

Specified by:

doWait in interface Driver

Parameters:

timeout - maximum time in milliseconds to wait. -1 means wait indefinitely.

listener

public Listener listener()

Description copied from interface: Driver

Get the next listener with pending data in the driver.

Specified by:

listener in interface Driver

Returns:

null if no active listener available

connector

public Connector connector()

Description copied from interface: Driver

Get the next active connector in the driver. Returns the next connector with pending inbound data, available capacity for outbound data, or pending tick. Clears the wake-up status that is set by Driver.wakeup().

Specified by:

connector in interface Driver

Returns:

null if no active connector available

destroy

public void destroy()

Description copied from interface: Driver

Destruct the driver and all associated listeners, connectors and other resources.

Specified by:

destroy in interface Driver

createListener

public <C> Listener<C> createListener(String host,
                             int port,
                             C context)

Description copied from interface: Driver

Construct a listener for the given address.

Specified by:

createListener in interface Driver

Parameters:

host - local host address to listen on

port - local port to listen on

context - application-supplied, can be accessed via getContext() method on a listener.

Returns:

a new listener on the given host:port, null if error

createListener

public <C> Listener<C> createListener(ServerSocketChannel c,
                             C context)

Description copied from interface: Driver

Create a listener using the existing channel.

Specified by:

createListener in interface Driver

Parameters:

c - existing SocketChannel for listener to listen on

context - application-supplied, can be accessed via getContext() method on a listener.

Returns:

a new listener on the given channel, null if error

createConnector

public <C> Connector<C> createConnector(String host,
                               int port,
                               C context)

Description copied from interface: Driver

Construct a connector to the given remote address.

Specified by:

createConnector in interface Driver

Parameters:

host - remote host to connect to.

port - remote port to connect to.

context - application-supplied, can be accessed via getContext() method on a listener.

Returns:

a new connector to the given remote, or null on error.

createConnector

public <C> Connector<C> createConnector(SelectableChannel c,
                               C context)

Description copied from interface: Driver

Create a connector using the existing file descriptor.

Specified by:

createConnector in interface Driver

Parameters:

c - existing SocketChannel for listener to listen on

context - application-supplied, can be accessed via getContext() method on a listener.

Returns:

a new connector to the given host:port, null if error.

removeConnector

public <C> void removeConnector(Connector<C> c)

listeners

public Iterable<Listener> listeners()

Description copied from interface: Driver

Return an iterator over all listeners.

Specified by:

listeners in interface Driver

connectors

public Iterable<Connector> connectors()

Description copied from interface: Driver

Return an iterator over all connectors.

Specified by:

connectors in interface Driver

createServerConnector

protected <C> Connector<C> createServerConnector(SelectableChannel c,
                                     C context,
                                     Listener<C> l)
