getGeometriesIntersecting method
Get the geometries of a tableName
intersecting a given geometry
.
Note that sqlite geopackage only supports RTree index, therefore the exact intersection is done after the getGeometriesIn call on the resulting geometries. This is NOT done on the db side.
@return The list of geometries intersecting the geometry. @deprecated use getGeometriesIn. This will be removed.
Implementation
List<Geometry?> getGeometriesIntersecting(TableName tableName,
{Geometry? geometry,
List<String>? prePostWhere,
int limit = -1,
String? userDataField}) {
if (geometry == null) {
return getGeometriesIn(tableName,
prePostWhere: prePostWhere,
limit: limit,
userDataField: userDataField);
} else {
var geometriesList = getGeometriesIn(
tableName,
envelope: geometry.getEnvelopeInternal(),
prePostWhere: prePostWhere,
limit: limit,
);
geometriesList
.removeWhere((geom) => geom != null && !geom.intersects(geometry));
return geometriesList;
}
}
