coordEach function
Iterates over coordinates in any geoJSONObject
, similar to Iterable.forEach
example:
var features = FeatureCollection(features: [
Feature(geometry: Point(coordinates: Position.of([26, 37])), properties: {'foo': 'bar'}),
Feature(geometry: Point(coordinates: Position.of([36, 53])), properties: {'foo': 'bar'})
]);
coordEach(features, (currentCoord, coordIndex, featureIndex, multiFeatureIndex, geometryIndex) {
//=currentCoord
//=coordIndex
//=featureIndex
//=multiFeatureIndex
//=geometryIndex
});
Implementation
void coordEach(GeoJSONObject geoJSON, Function callback,
[bool excludeWrapCoord = false]) {
_IndexCounter indexCounter = _IndexCounter();
try {
geomEach(
geoJSON,
(
GeometryType? currentGeometry,
int? featureIndex,
featureProperties,
featureBBox,
featureId,
) {
if (currentGeometry == null) return;
indexCounter.featureIndex = featureIndex ?? 0;
_forEachCoordInGeometryObject(
currentGeometry, callback, excludeWrapCoord, indexCounter);
},
);
} on ShortCircuit {
return;
}
}
