public class GraphHandler
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 only supports a graph. If several graphs can be created at the same time, the MulitGraphHandler shuld be used. To add the desired relations in the Graph, this class should be extended implementing the "endElement" method

Constructor Detail

GraphHandler

public GraphHandler()

Initialize the Handler with a new graph. Define "concept:name" as the default classifier for the event name.

GraphHandler

public GraphHandler(Graph graph)

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

Parameters:

graph - Graph

GraphHandler

public GraphHandler(Graph graph,
            java.lang.String classifier_name,
            java.lang.String classifier_keys)

Initialize the Handler with the provided graph. Uses the introduced classifier name as event name

Parameters:

dfg - Directly-follows graph

classifier_name - Classifier name

classifier_keys - Classifier keys
