Esempi in C# (CSharp) per Lucene.Net.Spatial.Queries SpatialArgsParser.Parse

Parse() public method

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

if the parameters don't make sense or an add-on parameter is unknown If there is a problem parsing the string When the coordinates are invalid for the shape

public Parse ( string v, SpatialContext ctx ) : SpatialArgs
v	string	The string to parse. Mandatory.
ctx	Spatial4n.Core.Context.SpatialContext	The spatial context. Mandatory.
return	SpatialArgs
