Class ReusableMessageFactory

java.lang.Object

org.apache.logging.log4j.message.ReusableMessageFactory

All Implemented Interfaces:

java.io.Serializable, MessageFactory, MessageFactory2

public final class ReusableMessageFactory
extends java.lang.Object
implements MessageFactory2, java.io.Serializable

Implementation of the MessageFactory interface that avoids allocating temporary objects where possible. Message instances are cached in a ThreadLocal and reused when a new message is requested within the same thread.

Since:

2.6
