booleanDisjoint function
Returns true
if the intersection of the two geometries is an empty set.
example:
var point = Point(coordinates: Position.of([2, 2]));
var line = LineString(
coordinates: [
Position.of([1, 1]),
Position.of([1, 2]),
Position.of([1, 3]),
Position.of([1, 4])
],
);
booleanDisjoint(line, point);
//=true
Implementation
bool booleanDisjoint(GeoJSONObject feature1, GeoJSONObject feature2) {
var bool = true;
flattenEach(
feature1,
(flatten1, featureIndex, multiFeatureIndex) {
flattenEach(
feature2,
(flatten2, featureIndex, multiFeatureIndex) {
if (!bool) {
return bool;
}
bool = _disjoint(flatten1.geometry!, flatten2.geometry!);
},
);
},
);
return bool;
}
