Process Mining Objects in Expression Language

This chapter lists all the object types in the expresssion language and properties and functions that they support. After the property or function name there is the type of the returned object mentioned. Asterisk (*) after the type means that it returns an array of objects.

Array

Array functions	Parameters	Description
IndexOfSubArray (Tnteger)	Optional object on which to operate Sub-array to search(array) Array from where to search the sub-array (array)	Returns the indexes of given sub-array (1. parameter) within the given array (2. parameter). If not given, the array in the current context object is used. Returns starting indexes of all the occurrences of given sub-array within given array. Examples: [[1,2,3,4,1,2,5]].IndexOfSubArray([1,2]) IndexOfSubArray([1,2], [1,2,3,4,1,2,5]) Return: [0, 4] [[1,2,3,4,1,2,5]].IndexOfSubArray([1,2,3,4,5]) Returns: [] [[1,2,3,4,1,2,5],[3,4],[0,1,2,3]]:IndexOfSubArray([1,2]) Returns: [ HierarchicalArray([1,2,3,4,1,2,5], [0,4]), HierarchicalArray([0,1,2,3], [1]) ]

AttributeType

AttributeType functions	Description
EventsHavingValue	Value to use for matching.	Returns all the event objects that have given value for this attribute. If the attribute type is a case attribute, then all the returned events belong to a case that has the specified value as the value of this case attribute. If the attribute type is an event attribute, then all the returned events have the specified value as the value of this event attribute. Examples: eventLog.EventAttributes.Where(Name=="SAP_User").EventsHavingValue("James") Returns: An array of events that have "James" as the value of "SAP_User" event attribute. eventLog.EventAttributes:EventsHavingValue("James") Returns: A hierarchical array of event attributes with each having a sub array of events that have "James" as the value of the parent event attribute. eventLog.CaseAttributes.Where(Name=="Region").EventsHavingValue("Dallas") Returns: An array of events that have "Dallas" as the value of their case's "Region" case attribute. eventLog.CaseAttributes:EventsHavingValue("Dallas") Returns: A hierarchical array of case attributes with each having a sub array of events that have "Dallas" as the value of the parent case attribute of their case.
CasesHavingValue	Value to use for matching.	Returns all the case objects that have given value for this attribute. If the attribute type is a case attribute, then all the returned cases have the specified value as the value of this case attribute. If the attribute type is an event attribute, then all the returned cases have at least one event that has the specified value as the value of this event attribute. Examples: eventLog.EventAttributes.Where(Name=="SAP_User").CasesHavingValue("James") Returns: An array of cases that have at least one event which has "James" as the value of "SAP_User" event attribute. eventLog.EventAttributes:CasesHavingValue("James") Returns: A hierarchical array of event attributes with each having a sub array of cases that have at least one event which has "James" as the value of the parent event attribute. eventLog.CaseAttributes.Where(Name=="Region").CasesHavingValue("Dallas") Returns: An array of cases that have "Dallas" as the value of "Region" case attribute. eventLog.CaseAttributes:CasesHavingValue("Dallas") Returns: A hierarchical array of case attributes with each having a sub array of cases that have "Dallas" as the value of the parent case attribute.

Expression

Expression is an object type that encapsulates a KPI expression language expression. Expression inside expression object can be evaluated by using the expression object as if it was a function by using <expression object name>(<parameter list>) syntax. Expression objects can be created in the following ways:

• Using Def function
• Whenever & prefix is used in Def function for an attribute

Examples:

Def(null, "a", "b", a+b)._(1,2)
Returns: 3

[Def("", "a", "b", a+b), Def("", "a", "b", a*b)].(_(1,2))
Returns: [3, 2]

Flow

Flow is a combination of two EventTypes where there are FlowOccurrences between them. Unlike FlowOccurrencies, a Flow is not related to a single case. Flowchart shows Flows and EventTypes (not FlowOccurences or Events). In a Case, the may be several FlowOccurrences of a single Flow.

Flow properties	Description
Cases (Case*)	Cases that contain the flow, i.e. there is a flow occurrence between Flow's starting and ending events.
FlowOccurrences (FlowOccurrence*)	Flow occurrences the flow belongs to.
From (EventType)	EventType from which this Flow starts.
Id (Integer)	Flow Id. It's generated by QPR ProcessAnalyzer when the model is loaded.
Name (String)	Identifying name of the Flow.
To (EventType)	EventType to which this Flow ends.

FlowOccurrence

FlowOccurrence represents a transition from an event to another event in a case. Thus, FlowOccurrence is related to a single case. There is also a FlowOccurrence from the "start" of the case to the first event of the case, and a FlowOccurrence from the last event of the case to the "end" of the case. Corresponding flow is visible in BPMN kind of flowcharts showing separate start and event icons. Thus, there are one more FlowOccurrences in a case than the number of events.

FlowOccurrence properties	Description
Case (Case)	Case the current FlowOccurrence belongs to.
Flow (Flow)	Corresponding Flow of the current FlowOccurrence.
From (Event)	Event where the current FlowOccurrence starts.
Id (Integer)	FlowOccurrence Id. It's generated by QPR ProcessAnalyzer when the model is loaded.
Name (String)	Identifying name of the current FlowOccurrence.
OccurrenceIndex (Integer)	Number tells how many times the current FlowOccurrence has occurred in the case until that point.
To (Event)	Event where the this FlowOccurrence ends.

Model

Model properties	Description
CaseAttributes (AttributeType*)	CaseAttributes of the model.
DefaultFilterId (Integer)	Id of the default filter for the model.
EventAttributes (AttributeType*)	EventAttributes of the model.
EventLog (EventLog)	EventLog of the model. Model EventLog contains all events of the model, i.e. no filters have been applied.
Id (Integer)	Model Id. Model Id is generated by QPR ProcessAnalyzer when the model is created.
Name (String)	Name of the model.
Project (Project)	The Project the this model belongs to.
