Concept Attributes Reference
Note: When using a concept in a rule’s form editor, type
conceptname.@ to see the list of its attributes.
You can use the following attributes in rules to return information about a concept instance.
Entity | Attributes | Type | Returns |
---|---|---|---|
Concept | @id | long | The concept instance’s unique internal ID. |
@extId | string | The concept instance’s unique external ID. Optional.
The value of the extId is set at creation time (for example, using the Instance.createInstance() function) and cannot be changed after that. |
|
ContainedConcept | @id | long | The contained concept instance’s unique internal ID. |
@extId | string | The contained concept instance’s unique external ID. | |
@parent | concept | The parent concept instance. (This is treated as a concept reference in the language.) | |
ConceptReference | @id | long | The contained concept instance’s unique internal ID. |
@extId | string | The contained concept instance’s unique external ID. | |
@isSet | boolean | Available for any concept property (not for referenced concepts). For example, you can use: acc.Balance@isSet. It indicates if a property is assigned or not. If a property is assigned, then @isSet returns true. |
