Class LogContext

java.lang.Object
org.apache.velocity.runtime.parser.LogContext
public class LogContext extends Object

Track location in template files during rendering by populating the slf4j MDC tags file, line and column.

An MDC-aware logger can then use this info to display the template location in the message

For instance with webapp-slf4j-logger, it's enough to use %file, %line and %column in the logger format string.

Since this feature can have a performance impact, it has to be enabled in velocity.properties using:

runtime.log.track_location = true

(typically in a development environment)
