public final class ValueExpression extends EncapsulatedIdentificationVariableExpression
VALUE operator is a path
expression. The VALUE operator may only be applied to identification
variables that correspond to map-valued associations or map-valued element collections.
The type of the path expression is the type computed as the result of the operation; that
is, the abstract schema type of the field that is the value of the VALUE
operator (the map value).
This is part of JPA 2.0.
