      • Partition

        public Partition​(CollectionsModel colMd,
                 java.lang.String uriTarget,
                 int descriptionDepth)
        Parameters:
        colMd - A preexisting CollectionsModel in which to describe the node and search for its neighbors
        uriTarget - The full length uri of the node to describe
        descriptionDepth - The depth of initial node description (the maximum distance a node can be to the initial node to describe it)

    • Method Detail

      • getClusters

        public java.util.List<Cluster> getClusters()
        Returns:
        A list containing all the clusters that are still partitionable Should always be empty at the end of the algorithm

      • getNeighbors

        public java.util.List<Cluster> getNeighbors()
        Returns:
        A list containing all the neighbors concepts, cluster that have been fully partitioned

      • oneStepPartitioning

        public boolean oneStepPartitioning()
                            throws PartitionException,
                                   java.lang.OutOfMemoryError
        Applies one iteration of the Partition algorithm
        Returns:
        false if the partitioning is over, true if it can still be iterated
        Throws:
        PartitionException
        java.lang.OutOfMemoryError

      • completePartitioning

        public int completePartitioning​(java.util.concurrent.atomic.AtomicBoolean cut)
        Applies the Partition algorithm to the end
        Parameters:
        cut - AtomicBoolean to observe, when it is set to false, the algorithm stops and cuts
        Returns:
        0 if the algorithm went to the end correctly, 1 if the algorithm encountered a memory limit, -1 if it encountered an unexpected error

      • cut

        public void cut()

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
