public class SqmLiteralEntityType<T>
extends AbstractSqmExpression<T>
implements SqmSelectableNode<T>, SemanticPathPart

Represents an reference to an entity type as a literal. This is the JPA terminology for cases when we have something like: ... where TYPE(e) = SomeType. The token SomeType is an "entity type literal". An entity type expression can be used to restrict query polymorphism. The TYPE operator returns the exact type of the argument.
