      public PreparedPoint(Puntal point)

  • Method Details

    • intersects

      public boolean intersects(Geometry g)
      Tests whether this point intersects a Geometry.

      The optimization here is that computing topology for the test geometry is avoided. This can be significant for large geometries.

      Specified by:
      intersects in interface PreparedGeometry
      Parameters:
      g - the Geometry to test
      Returns:
      true if this Geometry intersects the given Geometry

    • getGeometry

      public Geometry getGeometry()
      Description copied from interface: PreparedGeometry
      Gets the original Geometry which has been prepared.
      Specified by:
      getGeometry in interface PreparedGeometry
      Returns:
      the base geometry

    • getRepresentativePoints

      public List getRepresentativePoints()
      Gets the list of representative points for this geometry. One vertex is included for every component of the geometry (i.e. including one for every ring of polygonal geometries). Do not modify the returned list!
      Returns:
      a List of Coordinate

    • isAnyTargetComponentInTest

      public boolean isAnyTargetComponentInTest(Geometry testGeom)
      Tests whether any representative of the target geometry intersects the test geometry. This is useful in A/A, A/L, A/P, L/P, and P/P cases.
      Parameters:
      testGeom - the test geometry
      Returns:
      true if any component intersects the areal test geometry

    • envelopesIntersect

      protected boolean envelopesIntersect(Geometry g)
      Determines whether a Geometry g interacts with this geometry by testing the geometry envelopes.
      Parameters:
      g - a Geometry
      Returns:
      true if the envelopes intersect

    • envelopeCovers

      protected boolean envelopeCovers(Geometry g)
      Determines whether the envelope of this geometry covers the Geometry g.
      Parameters:
      g - a Geometry
      Returns:
      true if g is contained in this envelope
