/**
 * 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 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.

 * @version 2.4
