All Implemented Interfaces:

@Plugin(name="IndentingLayout",
        elementType="layout",
        category="Core",
        printObject=true)
public class IndentingLayout
extends org.apache.logging.log4j.core.layout.AbstractStringLayout

This is a special Log4j log formatter that is capable of reacting on special log messages and 'indent' the logs accordingly. This is very useful to visually inspect a debug log and see what calls what. An example of logs are > method() and < method() where > and < are used to indicate respectively "entering" and "exiting".
