Class DataPattern

java.lang.Object

org.processmining.partialorder.models.projection.DataPattern

public class DataPattern
extends java.lang.Object

A data pattern can be regarded as one edge (in the projection on process model) between a transition (or a log move) and a data attribute indicating an access to a data element observed in the log. The direction of the edge depends on the access type (I/O).

This class stores all information related to one data access pattern including (1) the attribute key, (2) the transition or the log move pattern which caused the data access, (3) the type (I/O) of the access, and (4) a map of all relevant trace indices and event indices to the XAttribute.

lmp - The log move pattern that accessed the data

i - Access type i that is either I (for input) or O (for output)

Method Detail

getPattern
