Class SplittingRateDataPartial

  • All Implemented Interfaces:
    SplittingRateData
    public class SplittingRateDataPartial
extends Object
implements SplittingRateData
    Store the splitting rates used during sLTM loading updates (Step 1 and 5). In this implementation we only track splitting rates of explicitly registered node. This is compatible with the basic PointQueue solution method where we do not require any information of nodes that are not potentially blocking. It requires the less memory than the other approach where we track all splitting rates of all used nodes.

      • SplittingRateDataPartial

        public SplittingRateDataPartial​(int numberOfVertices)
        Constructor
        Parameters:
        numberOfVertices - to expect at most

    • Method Detail

      • registerPotentiallyBlockingNode

        public void registerPotentiallyBlockingNode​(DirectedVertex potentiallyBlockingNode)
        Register a potentially blocking node so we not only track its splitting rates but also mark it as potentially blocking. This see to it that it is considered for node model updates which in turn might impact its splitting rates in a network setting
        Parameters:
        potentiallyBlockingNode - mark as potentially blocking (and track it if not already done so)

      • registerTrackedNode

        public void registerTrackedNode​(DirectedVertex trackNode)
        Register a node so we are able to track its splitting rates (and turn flows) during loading
        Parameters:
        trackNode - node to track splitting rates and (turn) sending flows for

      • isTracked

        public boolean isTracked​(DirectedVertex nodeToVerify)
        Verify if node is registered as being tracked with splitting rates
        Specified by:
        isTracked in interface SplittingRateData
        Parameters:
        nodeToVerify - the node to verify
        Returns:
        true when registered as tracked, false otherwise

      • isPotentiallyBlocking

        public boolean isPotentiallyBlocking​(DirectedVertex nodeToVerify)
        Verify if node is registered as potentially blocking
        Specified by:
        isPotentiallyBlocking in interface SplittingRateData
        Parameters:
        nodeToVerify - the node to verify
        Returns:
        true when registered as potentially blocking, false otherwise

      • getSplittingRates

        public org.ojalgo.array.Array1D<Double> getSplittingRates​(EdgeSegment entrySegment)
        Obtain the downstream splitting rates of given node entry segment (can be modified)
        Specified by:
        getSplittingRates in interface SplittingRateData
        Parameters:
        entrySegment - to obtain for
        Returns:
        currently set next splitting rates
