Method Detail

orderFromRootToLeaf

public static List<ExecutionEntity> orderFromRootToLeaf(Collection<ExecutionEntity> executions)

Takes in a collection of executions belonging to the same process instance. Orders the executions in a list, first elements are the leaf, last element is the root elements.

orderFromLeafToRoot

public static List<ExecutionEntity> orderFromLeafToRoot(Collection<ExecutionEntity> executions)

isReachable

                                  String sourceElementId,
                                  String targetElementId)

Verifies if the element with the given source identifier can reach the element with the target identifier through following sequence flow.
