Public Methods

Method Description
Parse ( string v, SpatialContext ctx ) : SpatialArgs

Parses a string such as "Intersects(ENVELOPE(-10,-8,22,20)) distErrPct=0.025".
WriteSpatialArgs ( SpatialArgs args ) : string

Writes a close approximation to the parsed input format.

Protected Methods

Method Description
NewSpatialArgs ( SpatialOperation op, IShape shape ) : SpatialArgs
ParseMap ( string body ) : string>.IDictionary

Parses "a=b c=d f" (whitespace separated) into name-value pairs. If there is no '=' as in 'f' above then it's short for f=f.
ParseShape ( string str, SpatialContext ctx ) : IShape
ReadBool ( string v, bool defaultValue ) : bool
ReadDouble ( string v ) : double?
ReadNameValuePairs ( SpatialArgs args, string>.IDictionary nameValPairs ) : void
