| /** |
| * This visitor traverses an {@link org.eclipse.persistence.jpa.jpql.parser.Expression Expression} |
| * and retrieves the "literal" value. The literal to retrieve depends on the {@link |
| * org.eclipse.persistence.jpa.jpql.LiteralType type}. The literal is basically a string value like |
| * an identification variable name, an input parameter, a path expression, an abstract schema name, etc. |

| * Provisional API: This interface is part of an interim API that is still under development and |
| * expected to change significantly before reaching stability. It is available at this early stage |
| * to solicit feedback from pioneering adopters on the understanding that any code that uses this |
| * API will almost certainly be broken (repeatedly) as the API evolves. |
