public class LogStream
extends java.util.LinkedList<org.deckfour.xes.model.XTrace>

This class represents a stream of a log. This class extends a priority queue, where its comparator is based on the timestamp attribute of the event log. As result, a stream is defined as a set of pairs of event and the referring trace.

Constructor Detail

LogStream

public LogStream()

Basic stream constructor. When the stream has been completely filled with the events, calculateStatistics() should be called.

Method Detail

calculateStatistics

public void calculateStatistics()

This method should be called in order to populate the minimum/maximum time between two activities and for calculating the total duration time of the log. This method, typically is called when the stream has been completely filled.

getMinTimeBetweenActivities

public long getMinTimeBetweenActivities()

This method returns the minimum time (as milliseconds) between all couples of activities

Returns:

the minTimeBetweenActivities

getMaxTimeBetweenActivities

public long getMaxTimeBetweenActivities()

This method returns the maximum time (as milliseconds) between all couples of activities

Returns:

the maxTimeBetweenActivities

getFirstExecutionTime

public java.util.Date getFirstExecutionTime()

This method returns the Date of the first execution

Returns:

the firstExecutionTime

getLastExecutionTime

public java.util.Date getLastExecutionTime()

This method returns the Date of the last execution

Returns:

the lastExecutionTime
