    • CUTINTS

      public static final boolean CUTINTS
      See Also:

    • x

      public double x
      The X coordinate of the point. In most long/lat systems, this is the longitude.

    • y

      public double y
      The Y coordinate of the point. In most long/lat systems, this is the latitude.

    • z

      public double z
      The Z coordinate of the point. In most long/lat systems, this is a radius from the center of the earth, or the height / elevation over the ground.

    • m

      public double m
      The measure of the point.

  • Constructor Details

    • Point

      public Point()

    • Point

      public Point(double x, double y, double z)
      Constructs a new Point
      Parameters:
      x - the longitude / x ordinate
      y - the latitude / y ordinate
      z - the radius / height / elevation / z ordinate

    • Point

      public Point(double x, double y)
      Constructs a new Point
      Parameters:
      x - the longitude / x ordinate
      y - the latitude / y ordinate

    • Point

      public Point(String value) throws SQLException
      Construct a Point from EWKT. (3D and measures are legal, but SRID is not allowed).
      Parameters:
      value - String representation of the geometry.
      Throws:
      SQLException - when a SQLException occurs

    • Point

      protected Point(String value, boolean haveM) throws SQLException
      Construct a Point
      Parameters:
      value - The text representation of this point
      haveM - Hint whether we have a measure. This is used by other geometries parsing inner points where we only get "1 2 3 4" like strings without the "POINT(" and ")" stuff. If there acutally is a POINTM prefix, this overrides the given value. However, POINT does not set it to false, as they can be contained in measured collections, as in "GEOMETRYCOLLECTIONM(POINT(0 0 0))".
      Throws:
      SQLException - when a SQLException occurs

    • checkConsistency

      public boolean checkConsistency()
      Description copied from class: Geometry
      Do some internal consistency checks on the geometry. Currently, all Geometries must have a valid dimension (2 or 3) and a valid type. 2-dimensional Points must have Z=0.0, as well as non-measured Points must have m=0.0. Composed geometries must have all equal SRID, dimensionality and measures, as well as that they do not contain NULL or inconsistent subgeometries. BinaryParser and WKTParser should only generate consistent geometries. BinaryWriter may produce invalid results on inconsistent geometries.
      Overrides:
      checkConsistency in class Geometry
      Returns:
      true if all checks are passed.
