FilterOperator Class
An operator that filters out features not fulfilling a condition.
NuGet/Assembly: Carmenta.Engine.5.17.0.nupkg (in the CEOperators assembly)
Syntax
public class FilterOperator : UnaryOperator
Remarks
This operator filters out features that do not fulfill a condition, specified by the Condition property. If the condition evaluates to True for a certain feature, the feature will be passed through the operator without modification. If it evaluates to False, the feature will be discarded and not processed any further.
If a dataset query can be used instead, that is often more efficient.
