intersectsPoint static method

bool intersectsPoint(Coordinate p1, Coordinate p2, Coordinate q)

Test the point q to see whether it intersects the Envelope defined by p1-p2 @param p1 one extremal point of the envelope @param p2 another extremal point of the envelope @param q the point to test for intersection @return true if q intersects the envelope p1-p2

Implementation

static bool intersectsPoint(Coordinate p1, Coordinate p2, Coordinate q) {
  //OptimizeIt shows that Math#min and Math#max here are a bottleneck.
  //Replace with direct comparisons. [Jon Aquino]
