Interface IWorkflowFlowAnalysis

All Superinterfaces:

Serializable

All Known Implementing Classes:

WorkflowFlowAnalysis

public interface IWorkflowFlowAnalysis
extends Serializable

Interface for querying info about the control and data flow of a workflow process. Instances should usually only represent the result of the analysis, the actual computation should be done before the instance is created (or during the constructor call).

Method Details

getEndPoints

IFlowGraphEndPoints getEndPoints(INodeKeyProviding node)

Convenience method for obtaining the task analysis, then using it to obtain the end points.

Parameters:

node - Node for which to find the end points.

Returns:

The end points of the given node. Never null, but might be empty if a non-existing node was given.

Since:

8.4.0

getPotentialPredecessorsOf

Set<NodeKey> getPotentialPredecessorsOf(NodeKey targetKey,
 FlowGraphFilter.Backward filter)

Parameters:

targetKey - The key of the target node to check.

filter - Filter applied when traversing the flow graph for finding paths from the target to preceding edges. See FlowGraphFilters for some common filters.

Returns:

The keys of all nodes for which isNodePotentiallyReachable(sourceUuid, nodeUuid, filter) returns true.

Since:

8.0.0

isNodePotentiallyReachable

@Deprecated
default boolean isNodePotentiallyReachable(NodeKey sourceKey,
 NodeKey targetKey)

Deprecated.

Use isNodePotentiallyReachable(sourceKey, targetKey, FlowGraphFilters.matchAll()).

Parameters:

sourceKey - Key of the source node to check.

targetKey - Key of the target node to check.

Returns:

Whether any code path includes a path where the source node was executed at the point in time the target node is about to be executed.

• ITaskFlowAnalysis.isPotentiallyReachable(NodeKey, NodeKey, FlowGraphFilter.Generic)

isNodePotentiallyReachable

boolean isNodePotentiallyReachable(NodeKey sourceKey,
 NodeKey targetKey,
 FlowGraphFilter.Generic filter)

Parameters:

sourceKey - Key of the source node to check.

targetKey - Key of the target node to check.

filter - Filter applied when traversing the flow graph for finding paths from the source to the target. See FlowGraphFilters for some common filters.

Returns:
