crosses method
Tests whether this geometry crosses the argument geometry.
The crosses
predicate has the following equivalent definitions:
- The geometries have some but not all interior points in common.
- The DE-9IM Intersection Matrix for the two geometries matches
one of the following patterns:
[T*T******]
(for P/L, P/A, and L/A situations)[T*****T**]
(for L/P, A/P, and A/L situations)[0********]
(for L/L situations)
false
.
The SFS defined this predicate only for P/L, P/A, L/L, and L/A situations. In order to make the relation symmetric, JTS extends the definition to apply to L/P, A/P and A/L situations as well.
@param g the Geometry
with which to compare this Geometry
@return true
if the two Geometry
s cross.
Implementation
bool crosses(Geometry g) {
// short-circuit test
if (!getEnvelopeInternal().intersectsEnvelope(g.getEnvelopeInternal()))
return false;
return relate(g).isCrosses(getDimension(), g.getDimension());
}
