Class ValueExpression<V>

java.lang.Object

org.springframework.amqp.rabbit.support.ValueExpression<V>

Type Parameters:

V - - The expected value type.

All Implemented Interfaces:

org.springframework.expression.Expression

public class ValueExpression<V>
extends Object
implements org.springframework.expression.Expression

A very simple hardcoded implementation of the Expression interface that represents an immutable value. It is used as value holder in the context of expression evaluation.

Since:

1.4
