Class EventStreamAggregatedLogger

java.lang.Object

com.videobug.agent.logging.io.EventStreamAggregatedLogger

All Implemented Interfaces:

IEventLogger

public class EventStreamAggregatedLogger
extends Object
implements IEventLogger

This class is an implementation of IEventLogger that records a sequence of runtime events in files. This object creates three types of files: 1. log-*.slg files recording a sequence of events, 2. LOG$Types.txt recording a list of type IDs and their corresponding type names, 3. ObjectIdMap recording a list of object IDs and their type IDs. Using the second and third files, a user can know classes in an execution trace.
