Method Detail

getTcpReceiveBufferSize

public int getTcpReceiveBufferSize()

start

public void start()
           throws Exception

Throws:

Exception

getName

public String getName()

Description copied from interface: Acceptor

The name of the acceptor used on the configuration. for logging and debug purposes.

getConnections

public Map<Object,NettyServerConnection> getConnections()

getProtocolHandler

public ProtocolHandler getProtocolHandler()

setKeyStoreParameters

public void setKeyStoreParameters(String keyStorePath,

Parameters:

channel - A Netty channel created outside this NettyAcceptor.

reload

public void reload()

Description copied from interface: Acceptor

public boolean isStarted()

pause

public void pause()

Description copied from interface: Acceptor

Pause the acceptor and stop it from receiving client requests.

Description copied from interface: Acceptor

Set the notification service for this acceptor to use.

Parameters:

notificationService - the notification service

setDefaultActiveMQPrincipal

public void setDefaultActiveMQPrincipal(ActiveMQPrincipal defaultActiveMQPrincipal)

not allowed

Parameters:

defaultActiveMQPrincipal -

isUnsecurable

public boolean isUnsecurable()

only InVM acceptors should allow this

isAutoStart

public boolean isAutoStart()

getActualPort

public int getActualPort()

Description copied from interface: Acceptor

This is a utility method for Socket-based acceptor implementations to get the actual port used. This is useful for configurations which specify a port number of 0 which allows the JVM to select an ephemeral port.

Returns:

the actual port used if using a Socket-based acceptor implementation; -1 otherwise
