public class SpatialArgsParser extends Object
SpatialArgs
object. The set of operations supported are defined in SpatialOperation
, such
as "Intersects" being a common one. The shape portion is defined by WKT WktShapeParser
,
but it can be overridden/customized via parseShape(String, org.locationtech.spatial4j.context.SpatialContext)
.
There are some optional name-value pair parameters that follow the closing parenthesis. Example:
Intersects(ENVELOPE(-10,-8,22,20)) distErrPct=0.025
In the future it would be good to support something at least semi-standardized like a variant of [E]CQL.
