Interface NetworkSpacialIndex2D

All Superinterfaces:
SpacialIndex2D<Long>
public interface NetworkSpacialIndex2D extends SpacialIndex2D<Long>
Stores the location and rectangular boundary of nodes in a 2D representation of a network. Also provides methods for querying edges that are adjacent to visible nodes. All methods support cancellation.
Since:
3.9

  • Method Details

    • queryAllNodes

      NodeSpacialIndex2DEnumerator queryAllNodes​(BooleanSupplier isCancelled)
      Returns an enumerator of all the nodes in the network. The enumerator will return nodes in the order given by the BasicVisualLexicon.NODE_Z_LOCATION visual property.
      Parameters:
      isCancelled - (May be null). An optional boolean returning function that will cancel a long running query if it returns true. The isCancelled function will typically be called several times depending on how many nodes are in the network. If isCancelled returns true then this method will return null.
      Returns:
      null if isCancelled returns null during the query
      See Also:
      BasicVisualLexicon.NODE_Z_LOCATION

    • queryOverlapNodes

      NodeSpacialIndex2DEnumerator queryOverlapNodes​(float xMin, float yMin, float xMax, float yMax, BooleanSupplier isCancelled)
      Returns an enumerator of all the nodes that are contained within or intersecting the given rectangle. The enumerator will return nodes in the order given by the BasicVisualLexicon.NODE_Z_LOCATION visual property.
      Parameters:
      isCancelled - (May be null). An optional boolean returning function that will cancel a long running query if it returns true. The isCancelled function will typically be called several times depending on how many nodes are in the network. If isCancelled returns true then this method will return null.
      Returns:
      null if isCancelled returns null during the query
      See Also:
      BasicVisualLexicon.NODE_Z_LOCATION

    • queryAllEdges

      EdgeSpacialIndex2DEnumerator queryAllEdges​(BooleanSupplier isCancelled)
      Returns an enumerator of all edges in the network. The enumerator will return edges in the order given by the BasicVisualLexicon.EDGE_Z_ORDER visual property.
      Parameters:
      isCancelled - (May be null). An optional boolean returning function that will cancel a long running query if it returns true. The isCancelled function will typically be called several times depending on how many edges are in the network. If isCancelled returns true then this method will return null.
      Returns:
      null if isCancelled returns null during the query
      See Also:
      BasicVisualLexicon.EDGE_Z_ORDER

    • queryOverlapEdges

      EdgeSpacialIndex2DEnumerator queryOverlapEdges​(float xMin, float yMin, float xMax, float yMax, BooleanSupplier isCancelled)
      Returns an enumerator of all edges that are adjacent to nodes that are contained within or intersecting the given rectangle. The enumerator will return edges in the order given by the BasicVisualLexicon.EDGE_Z_ORDER visual property.
      Parameters:
      isCancelled - (May be null). An optional boolean returning function that will cancel a long running query if it returns true. The isCancelled function will typically be called several times depending on how many edges are in the network. If isCancelled returns true then this method will return null.
      Returns:
      null if isCancelled returns null during the query
