Method Detail

getOrderedEvents

public static java.util.TreeMap<java.util.Date,java.util.ArrayList<org.deckfour.xes.model.XEvent>> getOrderedEvents(org.deckfour.xes.model.XLog eventlog)

Return a sorted map of for the given log.

Parameters:

eventlog - The event log

Returns:

The sorted map of events

filterLog

public static org.deckfour.xes.model.XLog filterLog(org.deckfour.xes.model.XLog eventlog,
                                                    java.util.Collection<java.lang.Integer> traceIndices)

Filter the log to only keep traces of which the indices are given.

Parameters:

eventlog - The original event log

traceIndices - The indices of traces to keep

Returns:

The filtered event log

filterLogUntil

public static org.deckfour.xes.model.XLog filterLogUntil(org.deckfour.xes.model.XLog eventlog,
                                                         java.util.Date timestamp,
                                                         boolean inclusive)

Filter the log to only keep events which occurred before or at (inclusive=true) the indicated time. Traces can be cut to remove events occurring after the given time, or can be removed completely (when they have no events before the given time).

Parameters:

eventlog - The original event log

timestamp - The time to look at

inclusive - Whether or not to keep events that occurred exactly on the given time.

Returns:

The filtered event log

filterLogActiveTraces

public static org.deckfour.xes.model.XLog filterLogActiveTraces(org.deckfour.xes.model.XLog eventlog,
                                                                java.util.Date timestamp)

Filter the log to only keep traces which were active at the given time. Traces can be cut to remove events occurring after the given time.

Parameters:

eventlog - The event log to filter.

timestamp - The time to look at.

Returns:

The filtered event log (active traces)

isActive

public static boolean isActive(org.deckfour.xes.model.XTrace trace,
                               java.util.Date timestamp)

Checks whether the given trace is active at the given time. A trace is considered active at a given time when it has events both before and after that time or exactly on that time.

Parameters:

trace - The trace to check.

timestamp - The time to look at.

Returns:

Whether or not the trace is active.
