code: public int getIntersectionCount(Envelope2D query, double tolerance, int maxCount) {
  		return m_impl.getIntersectionCount(query, tolerance, maxCount);
  	}
docs: Returns the number of elements in the quad tree that intersect the qiven query. Some elements may be duplicated if the quad tree stores duplicates.
  \param query The Envelope2D used for the query.
  \param tolerance The tolerance used for the intersection tests.
  \param max_count If the intersection count becomes greater than or equal to the max_count, then max_count is returned.
