public class MultiGraphHandler<G extends Graph>
extends org.xml.sax.helpers.DefaultHandler

The Handler for SAX Events in XES logs. This class is representing a Generic Handler for graphs. The handler only implements the "startElement" method. In this method, the events in a trace are stored and the events and traces are counted. The handler supports the creation of several graphs. To add the desired relations in the Graph, this class should be extended implementing the "endElement" method

Constructor Detail

MultiGraphHandler

public MultiGraphHandler(java.util.HashMap<MultiGraphHandler.GraphKeys,G> graphs)

Initialize the Handler with the provided pool of graphs. Define "concept:name" as the default classifier for the event name.

Parameters:

graphs - Pool of Graphs

MultiGraphHandler

public MultiGraphHandler(java.util.HashMap<MultiGraphHandler.GraphKeys,G> graphs,
                 java.lang.String classifier_name,
                 java.lang.String classifier_keys)

Initialize the Handler with the provided pool of graphs. Uses the introduced classifier name as event name

Parameters:

graphs - Pool of graphs

classifier_name - Classifier name

classifier_keys - Classifier keys
