Class TransportLoggerFactory

java.lang.Object

org.apache.activemq.transport.TransportLoggerFactory

public class TransportLoggerFactory
extends Object

Singleton class to create TransportLogger objects. When the method getInstance() is called for the first time, a TransportLoggerControlMBean is created and registered. This MBean permits enabling and disabling the logging for all TransportLogger objects at once.

Method Detail

getInstance

public static TransportLoggerFactory getInstance()

Returns a TransportLoggerFactory object which can be used to create TransportLogger objects.

Returns:

a TransportLoggerFactory object

stop

public void stop()

createTransportLogger

public TransportLogger createTransportLogger(org.apache.activemq.transport.Transport next)
                                      throws IOException

Creates a TransportLogger object, that will be inserted in the Transport Stack. Uses the default initial behavior, the default log writer, and creates a new log4j object to be used by the TransportLogger.

Parameters:

next - The next Transport layer in the Transport stack.

Returns:

A TransportLogger object.

Throws:

IOException

createTransportLogger

public TransportLogger createTransportLogger(org.apache.activemq.transport.Transport next,
                                             Logger log)
                                      throws IOException

Creates a TransportLogger object, that will be inserted in the Transport Stack. Uses the default initial behavior and the default log writer.

Parameters:

next - The next Transport layer in the Transport stack.

log - The log4j log that will be used by the TransportLogger.

Returns:

A TransportLogger object.

Throws:

IOException

createTransportLogger

public TransportLogger createTransportLogger(org.apache.activemq.transport.Transport next,
                                             String logWriterName,
                                             boolean useJmx,
                                             boolean startLogging,
                                             int jmxport)
                                      throws IOException

Creates a TransportLogger object, that will be inserted in the Transport Stack. Creates a new log4j object to be used by the TransportLogger.

Parameters:

next - The next Transport layer in the Transport stack.

startLogging - Specifies if this TransportLogger should be initially active or not.

logWriterName - The name or the LogWriter to be used. Different log writers can output logs with a different format.

Returns:

A TransportLogger object.

Throws:

IOException

createTransportLogger

public TransportLogger createTransportLogger(org.apache.activemq.transport.Transport next,
                                             int id,
                                             Logger log,
                                             String logWriterName,
                                             boolean dynamicManagement,
                                             boolean startLogging,
                                             int jmxport)
                                      throws IOException

Creates a TransportLogger object, that will be inserted in the Transport Stack.

Parameters:

next - The next Transport layer in the Transport stack.

id - The id of the transport logger.

log - The log4j log that will be used by the TransportLogger.

logWriterName - The name or the LogWriter to be used. Different log writers can output

dynamicManagement - Specifies if JMX will be used to switch on/off the TransportLogger to be created.

startLogging - Specifies if this TransportLogger should be initially active or not. Only has a meaning if dynamicManagement = true.

jmxport - the port to be used by the JMX server. It should only be different from 1099 (broker's default JMX port) when it's a client that is using Transport Logging. In a broker, if the port is different from 1099, 2 JMX servers will be created, both identical, with all the MBeans.

Returns:

A TransportLogger object.

Throws:

IOException
