getTransportMetadata

public TransportMetadata getTransportMetadata()

Description copied from interface: IoService

Returns the TransportMetadata that this service runs on.

Specified by:

getTransportMetadata in interface IoService

getSessionConfig

public DatagramSessionConfig getSessionConfig()

Description copied from class: AbstractIoService

Returns the default configuration of the new IoSessions created by this service.

Specified by:

getSessionConfig in interface IoService

Overrides:

getSessionConfig in class AbstractIoService

getLocalAddress

public InetSocketAddress getLocalAddress()

Description copied from class: AbstractIoAcceptor

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

Specified by:
