Method Details

addRelationshipLimiters

public void addRelationshipLimiters(String rootEntityGUID,
 List<String> relationshipTypeGUIDs,
 List<InstanceStatus> limitResultsByStatus)

Add condition(s) to limit the resulting relationships by the provided lists.

Parameters:

rootEntityGUID - by which to narrow the relationships

relationshipTypeGUIDs - of relationship type definition GUIDs by which to limit the results

limitResultsByStatus - of relationship statuses by which to limit the results

addEntityLimiters

public void addEntityLimiters(List<String> entityTypeGUIDs,
 List<String> limitResultsByClassification,
 List<InstanceStatus> limitResultsByStatus)

Add condition(s) to limit the resulting entities by the provided criteria.

Parameters:

entityTypeGUIDs - entity type definitions by which to limit

limitResultsByClassification - entity classifications by which to limit

limitResultsByStatus - of entity statuses by which to limit the results

getClassificationConditions

protected List<clojure.lang.IPersistentCollection> getClassificationConditions(List<String> limitByClassifications)

Add condition(s) to limit the resulting entities by the provided classifications.

Parameters:

limitByClassifications - of classifications on which to limit (must be at least one)

Returns:

List<IPersistentCollection> of the conditions

getRelatedToCondition

protected clojure.lang.PersistentVector getRelatedToCondition()

Add a condition to match the value of a property to a variable.

Returns:

PersistentVector for the condition

getRelatedToCondition

protected clojure.lang.PersistentVector getRelatedToCondition(String literal)

Add a condition to match the value of a property to a literal.

Parameters:

literal - to match

Returns:

PersistentVector for the condition
