Method Detail

setDelayed

public abstract void setDelayed(boolean delayed)

Sets delayed creation of TCP listeners and connectors

Parameters:

delayed -

startDelayed

public abstract void startDelayed()
                           throws java.lang.Exception

Starts delayed TCP listeners and connectors

Throws:

java.lang.Exception

isReuseServerSocket

public abstract boolean isReuseServerSocket()

Returns whether server sockets should be re-used after a reboot of a router

Returns:

true/false

isDnsResolve

public abstract boolean isDnsResolve()

Returns whether DNS resolution is enabled

Returns:

createTCPListener

public abstract void createTCPListener(ListenerMetaData metaData)
                                throws java.lang.Exception

Create a TCP listener. The listener is specified through the meta data. Incoming connections on this listeners are passed to a ConnectionListener which decides to accept the connection.

Parameters:

metaData - listener meta data

Throws:

java.lang.Exception - on error.

See Also:

ConnectionListener

removeTCPListener

public abstract void removeTCPListener(ListenerMetaData metaData)

Removes a TCP listener.

Parameters:

metaData - listener meta data

createIntraVMListener

public abstract void createIntraVMListener(IntraVMListenerMetaData metaData)
                                    throws java.lang.Exception

Create an intra-VM listener. The listener is specified through the meta data. Incoming connections on this listeners are passed to a ConnectionListener which decides to accept the connection.

Parameters:

metaData - intra-VM listener meta data

Throws:

java.lang.Exception - on error.

See Also:

ConnectionListener

removeIntraVMListener

public abstract void removeIntraVMListener(IntraVMListenerMetaData metaData)

Removes a intra-VM listener.

Parameters:

metaData - intra-VM listener meta data

connectIntraVMListener

public abstract void connectIntraVMListener(java.lang.String swiftletName,
                                            IntraVMConnection connection)
                                     throws java.lang.Exception

Connects to an intra-VM listener.

Parameters:

swiftletName - swiftlet name

connection - intra-VM client connection

Throws:

java.lang.Exception - on error.

createTCPConnector

public abstract void createTCPConnector(ConnectorMetaData metaData)
                                 throws java.lang.Exception

Create a TCP connector. A connector is a single outgoing connection, specified by the meta data. A connector has a retry interval. If a connection can't be established, further attempts in the retry interval will be made. After a TCP connection is established, the ConnectionListener will be informed to accept the connection.

Parameters:

metaData - connector meta data.

Throws:

java.lang.Exception - on error.

See Also:

ConnectionListener

removeTCPConnector

public abstract void removeTCPConnector(ConnectorMetaData metaData)

Removes a TCP connector

Parameters:

metaData - connector meta data.

getConnectionManager

public ConnectionManager getConnectionManager()

Returns the connection manager

Returns:

connection manager.

setConnectionManager

protected void setConnectionManager(ConnectionManager connectionManager)

Set the connection manager

Parameters:

connectionManager - connection manager.
