class pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.Parameters(value)[source]

Bases: enum.Enum

An enumeration.

EPSILON = 'epsilon'
START_TIMESTAMP_KEY = 'pm4py:param:start_timestamp_key'
TIMESTAMP_KEY = 'pm4py:param:timestamp_key'
pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.apply(log: pm4py.objects.log.obj.EventLog, parameters: Optional[Dict[Any, Any]] = None) intervaltree.intervaltree.IntervalTree[source]

Transforms the event log to an interval tree in which the intervals are the directly-follows paths in the log (open at the complete timestamp of the source event, and closed at the start timestamp of the target event), and having as associated data the source and the target event.

Parameters
  • log – Event log

  • parameters – Parameters of the algorithm, including: - Parameters.START_TIMESTAMP_KEY => the attribute to be used as start timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.TIMESTAMP_KEY => the attribute to be used as completion timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.EPSILON => the small gap that is removed from the timestamp of the source event and added to the

    timestamp of the target event to make interval querying possible

Returns

Interval tree object (which can be queried at a given timestamp, or range of timestamps)

Return type

tree
