    • Method Detail

      • extractTaskSequences

        Set<NESTWorkflowObject> extractTaskSequences​(int minLength)
        Extracts each longest sequence of task nodes without controlflow nodes and with at least minLength tasks
        Parameters:
        minLength - minimum number of tasks in a sequence
        Returns:
        set of nest workflow graphs with task sequences

      • extractSingleTaskBlocks

        Set<NESTWorkflowObject> extractSingleTaskBlocks()
        Returns a set of nest workflow graphs where each graph contains a single task node from the given workflow graph.
        Returns:
        set of nest workflow graphs

      • extractSingleTaskBlocks

        Set<NESTWorkflowObject> extractSingleTaskBlocks​(Predicate<NESTTaskNodeObject> filter)
        Returns a set of nest workflow graphs where each graph contains a single task node from the given workflow graph.
        Parameters:
        filter - filter for the tasks to be extracted
        Returns:
        set of nest workflow graphs

      • extractWorkflowBlocks

        Set<NESTWorkflowObject> extractWorkflowBlocks()
        Returns a set of nest workflow graphs that are blocks of a block-oriented workflow graph. Returns the following elements as a single graph: - each single task node, - each longest sequence of task nodes without controlflow nodes with at least two tasks, - each controlflow block with contained sequences Returns null if the given nest workflow graph is not block-oriented.
        Returns:
        set of nest workflow graphs

      • extractPartialGraphComponents

        Set<NESTWorkflowObject> extractPartialGraphComponents()
        Returns a set of partial nest workflow graph for those sequence nodes that are connected via the control-flow and a set of partial nest graphs containing unlinked data objects.
        Returns:
        set of partial nest workflow graphs

      • extractPartialGraph

        NESTWorkflowObject extractPartialGraph​(Collection<NESTSequenceNodeObject> componentNodes,
                                       boolean removeUnusedControlflowBlocks)
        Returns a cloned partial nest workflow graph for a given set of sequence nodes.
        Parameters:
        componentNodes - the set of sequence nodes that are contained in the nest graph
        removeUnusedControlflowBlocks - defined whether unused control-flow blocks are removed
        Returns:
        cloned partial nest workflow graph

      • extractPartialGraph

        NESTWorkflowObject extractPartialGraph​(NESTSequenceNodeObject componentNodes,
                                       boolean removeUnusedControlflowBlocks)
        Returns a cloned partial nest workflow graph for a sequence node.
        Parameters:
        componentNodes - the set of sequence nodes that are contained in the nest workflow graph
        removeUnusedControlflowBlocks - defined whether unused control-flow blocks are removed
        Returns:
        cloned partial nest workflow graph
