Interface VirtualFieldCriteriaExpanderInterface

public interface VirtualFieldCriteriaExpanderInterface

Converts a virtual field into ordinary query filters. Implementations reject unsupported operators with QUserFacingException. Returned filters must not contain further expander criteria; expansion is a single pass.
