Package org.apache.logging.log4j.message

Class ParameterizedNoReferenceMessageFactory

java.lang.Object

org.apache.logging.log4j.message.AbstractMessageFactory

org.apache.logging.log4j.message.ParameterizedNoReferenceMessageFactory

All Implemented Interfaces:

Serializable, MessageFactory, MessageFactory2

public final class ParameterizedNoReferenceMessageFactory
extends AbstractMessageFactory

Creates FormattedMessage instances for MessageFactory2 methods (and MessageFactory by extension.)

Creates SimpleMessage objects that do not retain a reference to the parameter object.

Intended for use by the StatusLogger: this logger retains a queue of recently logged messages in memory, causing memory leaks in web applications. (LOG4J2-1176)

This class is immutable.

Note to implementors:

This class does not implement any MessageFactory2 methods and lets the superclass funnel those calls through newMessage(String, Object...).
