public class EntityValidationRSQLVisitor
extends ValidationRSQLVisitor

RSQL AST visitor that validates selectors directly against an entity model.

This visitor resolves request selectors to entity fields, applies any configured FieldMapping aliases, and ensures that the resolved terminal field is filterable for the requested operator.

It is typically used by entity-aware specification resolvers before converting a parsed RSQL tree into a Spring Data JPA Specification.
