ToString

Properties

• property FieldId as %Integer;

• property FilterOperator as %String;

• property FilterValue as %String;

Methods

• method ToString() as %String

Subclasses should implement this method to build a string representation of the filter instance. It should start with the filter class name, followed by a pipe (|) character and then a string representation that can be interpreted by its RestoreFilterFromStringInternal implementation.
