  +--opencard.core.util.Tracer
public class Tracer
extends java.lang.Object

Utility class for tracing. Each class that wants its operations traced needs to instantiate a Tracer object specifying a tag to enable it by. Tracing at runtime is controlled through the set of tags configured in the opencard.tracer property:

tag
Trace all messages submitted under tag or any tag beginning with tag
tag:level
Trace all message with a level greater or equal to level submitted under tag or any tag beginning with tag
