[System::Runtime::CompilerServices::Extension]
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ IsClosedSpatial(System::Data::Common::CommandTrees::DbExpression ^ spatialValue);
public static System.Data.Common.CommandTrees.DbFunctionExpression IsClosedSpatial (this System.Data.Common.CommandTrees.DbExpression spatialValue);
static member IsClosedSpatial : System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
<Extension()>
Public Function IsClosedSpatial (spatialValue As DbExpression) As DbFunctionExpression

Parameters

spatialValue
DbExpression

An expression that specifies the spatial curve value from which the IsClosedSpatial value should be retrieved.
