intersects method

bool intersects(Geometry geom)

Tests whether the given Geometry intersects the query rectangle.

@param geom the Geometry to test (may be of any type) @return true if the geometry intersects the query rectangle

Implementation

  if (!rectEnv.intersectsEnvelope(geom.getEnvelopeInternal())) return false;

   * Test if rectangle envelope intersects any component envelope.
   * This handles Point components as well
   */

   * Test if any rectangle vertex is contained in the target geometry
   */
