Description copied from interface: NESTAbstractWorkflowModifier

Adds a given sub-graph into a target graph this modifier is responsible for. A parent node (of the target graph) can be set. Otherwise, the workflow node of the target workflow is used as parent node The pre node and the post node are nodes that will be connected to the start node or the end node, respectively. All nodes and edges of the sub-graph will be copied into the target graph. Consequently, the ids will be altered! A map that contains the old-to-new-mapping-ID's is returned by this method.

Specified by:

insertSubgraph in interface NESTAbstractWorkflowModifier

Overrides:

insertSubgraph in class NESTAbstractWorkflowModifierImpl<NESTWorkflowObject>

Parameters:

subgraphToInsert - the sub-graph that should be added to the target graph

preNode - node of the target graph; this node will be connected to the start node of the sub-graph with a control-flow edge. If preNode is null, no control-flow edge is inserted.

postNode - node of the target graph; the end node of the sub-graph will be connected to this node with a control-flow edge. If postNode is null, no control-flow edge is inserted.

parentNode - workflow node or sub-workflow node of the target graph; all nodes that were previously connected to the workflow node of the sub-graph will be linked to the parent node via part-of edges. If parentNode is null, the workflow node of the target workflow is used as parent node.

Returns:

a map that contains the old-to-new-mapping-ID's
