Dynamic Appenders
Each logger object has several methods that you can use in order to interact with the logger's appenders. You can add, remove, clear or list the appenders on a specific logger instance. Below are the methods you can use in the logger class to interact with appenders:
Method | Return Type | Description |
hasAppenders() | Boolean | Checks if the logger has any appenders attached to it |
getAppenders() | Struct | Returns the map of registered appenders |
getAppender(name) | Appender | Return a named appender if it is registered in the logger |
appenderExists(name) | Boolean | Checks if a named appender exists in the logger |
addAppender(Appender) | void | Register an appender with the logger at runtime |
removeAppender(name) | Boolean | Will un-register an appender from this logger |
removeAllAppenders() | void | Will try to un-register all appenders from this logger |
So you can easily add/remove/check the appenders on any logger at any time.
//Add your own appender at runtime
jms = createObject( "component", "com.appender.JMSAppender" ).init( "JMSAppender", properties );
logger.addAppender( jms );
//log a message to all appenders and to my jms appender:
logger.fatal( "I FAILED MAN!" );
//remove it
logger.removeAppender( "JMSAppender" );
