      protected Geometry(int type)
      Constructor for subclasses.
      Parameters:
      type - has to be given by all subclasses

  • Method Details

    • checkConsistency

      public boolean checkConsistency()
      Do some internal consistency checks on the geometry. Currently, all Geometries must have a valid dimension (2 or 3) and a valid type. 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.
      Returns:
      true if all checks are passed.

    • equals

      public boolean equals(@Nullable Object obj)
      java.lang.Object equals implementation
      Overrides:
      equals in class Object
      Parameters:
      obj - geometry to compare
      Returns:
      true if equal, false otherwise

    • getCoordinates

      public abstract Iterable<Point> getCoordinates()
      Gets the coordinates of this Geometry.
      Returns:
      coordinates

    • getNumberOfCoordinates

      public abstract int getNumberOfCoordinates()
      Gets the number of coordinates of this Geometry.
      Returns:
      number of coordinates

    • getSrid

      public int getSrid()
      The OGIS geometry type number of this geometry.
      Returns:
      the SRID of this geometry

    • getType

      public int getType()
      Gets the OGIS geometry type number of this geometry.
      Returns:
      type of this geometry

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • hasMeasure

      public abstract boolean hasMeasure()
      Returns whether we have a measure (4th dimension)
      Returns:
      true if the geometry has a measure, false otherwise

      Checks if this Geometry is 3d.
      Returns:
      true on success, else false

    • isEmpty

      public abstract boolean isEmpty()
      Ist this Geometry empty, so does it contain no coordinates or other geometries?
      Returns:
      true on success, else false

    • setSrid

      public void setSrid(int srid)
      Recursively sets the srid on this geometry and all contained subgeometries
      Parameters:
      srid - the SRID for this geometry
