Interface ConstantNode

All Superinterfaces:
Element, ExpressionNode, javax.jmi.reflect.RefBaseObject, javax.jmi.reflect.RefFeatured, javax.jmi.reflect.RefObject

public interface ConstantNode
extends ExpressionNode

Instances of the ConstantNode class are ExpressionNodes that represent constant values within expressions. Appropriate uses of the ConstantNode class place the values of constants in the value attribute, rather than in the expression::body attribute inherited from ExpressionNode. The latter attribute is intended for a different purpose; see the description of the ExpressionNode class for details.

          The value of a constant in an expression tree.
 void setValue(java.lang.Object newValue)
