org.apache.velocity.runtime.log.Log

org.apache.velocity.runtime.log.LogDisplayWrapper

public class LogDisplayWrapper
extends Log

This is a wrapper around a log object, that can add a prefix to log messages and also turn logging on and off dynamically. It is mainly used to control the logging of VelociMacro generation messages but is actually generic enough code.
