Method Summary

Modifier and Type	Method and Description
protected void	analyzeEvent(org.deckfour.xes.model.XTrace trace, boolean isTraceStart, boolean isTraceComplete) This method is responsible of the actual analysis of the provided trace (containing only one event)
protected void	cacheCleanup() This method cleans up the cache
protected java.util.Collection<org.processmining.framework.util.Pair<java.lang.String,java.lang.String>>	getLogStartEnd() This method is required in order to obtain the set of pairs of events that are allowed to start and end each trace.
void	setup(MinerConfiguration configuration) This method is called before that the actual mining start
protected java.lang.Object	updateModel() This method is called all the time that (if configured) the model needs to be updated

Method Detail

setup

public void setup(MinerConfiguration configuration)

Description copied from class: OnlineMiningAlgorithm

This method is called before that the actual mining start

Specified by:

setup in class OnlineMiningAlgorithm

analyzeEvent

protected void analyzeEvent(org.deckfour.xes.model.XTrace trace,
                            boolean isTraceStart,
                            boolean isTraceComplete)

Description copied from class: OnlineMiningAlgorithm

This method is responsible of the actual analysis of the provided trace (containing only one event)

Specified by:

analyzeEvent in class OnlineMiningAlgorithm

Parameters:

trace - the trace observed

isTraceStart - this variable is set to true if the event collected is explicitly marked as the first event of the trace

isTraceComplete - this variable is set to true if the event collected is explicitly marked as the last event of the trace

updateModel

protected java.lang.Object updateModel()

Description copied from class: OnlineMiningAlgorithm

This method is called all the time that (if configured) the model needs to be updated

Specified by:

updateModel in class OnlineMiningAlgorithm

Returns:

a representation of the model

cacheCleanup

protected void cacheCleanup()

Description copied from class: CNetBasedOnlineMiningAlgorithm

This method cleans up the cache

Overrides:

cacheCleanup in class CNetBasedOnlineMiningAlgorithm

getLogStartEnd

protected java.util.Collection<org.processmining.framework.util.Pair<java.lang.String,java.lang.String>> getLogStartEnd()

Description copied from class: CNetBasedOnlineMiningAlgorithm

This method is required in order to obtain the set of pairs of events that are allowed to start and end each trace. This method is allowed to return and empty collection.

Specified by:

getLogStartEnd in class CNetBasedOnlineMiningAlgorithm

Returns:

the collection of pairs
