Use the simple navigation operation type, if you need to specify a direct relation between the elements through model relationships, properties, tags, or UML operations. 


To specify a simple navigation as criteria

  1. Click Simple Navigation on the left side of the dialog.
  2. Select a relationship, property, tag, or operation.
  3. Specify other options described in the table below:
ColumnModeDescription

Relation Criterion

Standard/Expert

Name of a relationship, property, tag, or UML meta-operation. The whole list is by default filtered and shows only these relationships, properties, tags, and operations that are available for the Contextual element type. To see the full list, click to clear the check box below the list.

Is Applied

Standard/Expert

Select the check box to define the appropriate relationship, property, tag, or UML operation as criteria for the calculation. To clear all the selected criteria, click the Clear All button.

Direction

Standard/Expert

Select from the drop-down list the direction of the appropriate relationship, property, tag, or UML operation.
A source is the Contextual element.
A target is the result of the calculation.


If the direction is defined for relationships, then

• The Source To Target direction means that only the outgoing relations, which are pointing from the source element to the target element, will be treated as a result of this criterion.
• The Target To Source direction means that only the incoming relations, which are pointing from the target element to the source element, will be treated as a result of this criterion.
• If the Both direction is chosen, both above-described cases will be treated as a valid result.


If the direction is defined for properties or tags, then

• The Source To Target direction means that only the properties, which exist in the source element, will be treated as a result of this criterion.
• The Target To Source direction means that only the properties, which exist in the target element, will be treated as a result of this criterion.
• If the Both direction is chosen, both above-described cases will be treated as a valid result.


Operations support the Source To Target direction only.

Please note that the Simple Navigation operation returns a set.


Manipulations in Expert mode

The Expert mode allows for changing the Contextual element of a simple navigation criterion as well as creating a new operation, where the result of the simple navigation operation is used as an argument.
