Class CoordinateArraySequence

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, CoordinateSequence

    public class CoordinateArraySequence
extends java.lang.Object
implements CoordinateSequence, java.io.Serializable
    A CoordinateSequence backed by an array of Coordinates. This is the implementation that Geometrys use by default. Coordinates returned by #toArray and #getCoordinate are live -- modifications to them are actually changing the CoordinateSequence's underlying data. A dimension may be specified for the coordinates in the sequence, which may be 2 or 3. The actual coordinates will always have 3 ordinates, but the dimension is useful as metadata in some situations.

      • getCoordinate

        public Coordinate getCoordinate​(int i)
        Get the Coordinate with index i.
        Specified by:
        getCoordinate in interface CoordinateSequence
        Parameters:
        i - the index of the coordinate
        Returns:
        the requested Coordinate instance

      • getCoordinateCopy

        public Coordinate getCoordinateCopy​(int i)
        Get a copy of the Coordinate with index i.
        Specified by:
        getCoordinateCopy in interface CoordinateSequence
        Parameters:
        i - the index of the coordinate
        Returns:
        a copy of the requested Coordinate

      • getOrdinate

        public double getOrdinate​(int index,
                          int ordinateIndex)
        Description copied from interface: CoordinateSequence
        Returns the ordinate of a coordinate in this sequence. Ordinate indices 0 and 1 are assumed to be X and Y. Ordinates indices greater than 1 have user-defined semantics (for instance, they may contain other dimensions or measure values).

        Parameters:
        index - the coordinate index in the sequence
        ordinateIndex - the ordinate index in the coordinate (in range [0, dimension-1])
