Method Detail

isNonBlockingSubCase

public static boolean isNonBlockingSubCase(CasePlanModel caze)

isServiceTask

public static boolean isServiceTask(PlanItem planItem)

isBpmnProcessTask

public static boolean isBpmnProcessTask(PlanItem planItem)

createLogicalModelStructure

public static HashMap<String,PlannableItem> createLogicalModelStructure(TDefinitions tDefinitions)

Create an in-memory representation of the logical structure of a case model. Currently only considers plan items (no discretionary items). Collects plan items from plan fragments but skips the plan fragments themselves, as they do not contribute to the run-time structure of a model.

Parameters:

tDefinitions - the definitions extracted from the CMMN XML.

Returns:

the map of plannable items representing the model, keyed by model IDs.

extractHumanTasks

public static List<THumanTask> extractHumanTasks(TDefinitions tDefinitions)

Given the structure of a CMMN XML in tDefinitions, navigate though it and return all contained THumanTask elements as a list. The method returns all the definitions of human task plan items or human task discretionary items due to the fact that we assume a 1:1 mapping between a plan item or discretionary item and its definition and also due to the fact that the structure of definitions is dictated by the structure of stage definitions (no need to descend into plan fragments or planning tables).

Parameters:

tDefinitions - the XML model in which to look.

Returns:

the list of THumanTask elements found. May be empty but never null.

extractPlanItems

public static List<TPlanItem> extractPlanItems(TDefinitions tDefinitions,
                                               Class<? extends TPlanItemDefinition> type)

Given the structure of a CMMN XML in tDefinitions, navigate though it and return all plan items that are assignable to the type passed in. Note: the CasePlanModel itself is never returned as a plan item.

Parameters:

tDefinitions - the XML model in which to look.

type - the type of plan item you’re interested in.

Returns:

the list of TPlanItemDefinition elements found. May be empty but never null.

getCase

public static TCase getCase(TDefinitions tDefinitions)

Get the case for a CMMN XML. We only support exactly one TCase per CMMN XML.

Parameters:

tDefinitions - the root element.

Returns:

the one case element.
