Field Detail

bindLock

protected final Object bindLock

The lock object which is acquired while bind or unbind operation is performed. Acquire this lock in your property setters which shouldn't be changed while the service is bound.

Constructor Detail

AbstractIoAcceptor

protected AbstractIoAcceptor(IoSessionConfig sessionConfig,
                             Executor executor)

Constructor for AbstractIoAcceptor. You need to provide a default session configuration and an Executor for handling I/O events. If null Executor is provided, a default one will be created using Executors.newCachedThreadPool().

Parameters:

sessionConfig - the default configuration for the managed IoSession

executor - the Executor used for handling execution of I/O events. Can be null.

See Also:

AbstractIoService(IoSessionConfig, Executor)

Method Detail

getLocalAddress

public SocketAddress getLocalAddress()

Returns the local address which is bound currently. If more than one address are bound, only one of them will be returned, but it's not necessarily the firstly bound address.

Specified by:

getLocalAddress in interface IoAcceptor

Returns:

The bound LocalAddress

Specified by:

getLocalAddresses in interface IoAcceptor

Returns:

The Set of bound LocalAddresses

getDefaultLocalAddress

public SocketAddress getDefaultLocalAddress()

Returns the default local address to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified. If more than one address are set, only one of them will be returned, but it's not necessarily the firstly specified address in IoAcceptor.setDefaultLocalAddresses(List).

Specified by:

getDefaultLocalAddress in interface IoAcceptor

Returns:

The default bound LocalAddress

setDefaultLocalAddress

public final void setDefaultLocalAddress(SocketAddress localAddress)

Sets the default local address to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified.

Specified by:

setDefaultLocalAddress in interface IoAcceptor

Parameters:

localAddress - The local addresses to bind the acceptor on

getDefaultLocalAddresses

public final List<SocketAddress> getDefaultLocalAddresses()

Returns a List of the default local addresses to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified.

Specified by:

getDefaultLocalAddresses in interface IoAcceptor

Returns:

The list of default bound LocalAddresses

setDefaultLocalAddresses

public final void setDefaultLocalAddresses(List<? extends SocketAddress> localAddresses)

Sets the default local addresses to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified.

Specified by:

setDefaultLocalAddresses in interface IoAcceptor

Parameters:

localAddresses - The local addresses to bind the acceptor on

setDefaultLocalAddresses

public final void setDefaultLocalAddresses(Iterable<? extends SocketAddress> localAddresses)

Sets the default local addresses to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified.

Specified by:

setDefaultLocalAddresses in interface IoAcceptor

Parameters:

localAddresses - The local addresses to bind the acceptor on

setDefaultLocalAddresses

public final void setDefaultLocalAddresses(SocketAddress firstLocalAddress,
                                           SocketAddress... otherLocalAddresses)

Sets the default local addresses to bind when no argument is specified in IoAcceptor.bind() method. Please note that the default will not be used if any local address is specified.
