protected boolean doWriteMessage(java.lang.Object msg) throws java.lang.Exception
- Throws:
java.lang.Exception
-
filterOutboundMessage
protected java.lang.Object filterOutboundMessage(java.lang.Object msg)
Description copied from class:AbstractChannel
Invoked when a new message is added to aChannelOutboundBuffer
of thisAbstractChannel
, so that theChannel
implementation converts the message to another. (e.g. heap buffer -> direct buffer)- Overrides:
filterOutboundMessage
in classAbstractChannel
-
isActive
public boolean isActive()
Description copied from interface:Channel
Returntrue
if theChannel
is active and so connected.
-
isConnected
public boolean isConnected()
Description copied from interface:DomainDatagramChannel
Returntrue
if theDomainDatagramChannel
is connected to the remote peer.- Specified by:
isConnected
in interfaceDomainDatagramChannel
-
localAddress
public DomainSocketAddress localAddress()
Description copied from interface:Channel
Returns the local address where this channel is bound to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
localAddress
in interfaceChannel
- Specified by:
localAddress
in interfaceDomainDatagramChannel
- Overrides:
localAddress
in classAbstractChannel
- Returns:
