public interface Immediate

An Immediate is any Expression that can be evaluated without evaluating any other expressions. Immediate Expressions must override the getValue method to return a non-null value. Declaring an Expression to be immediate allows the engine to optimize the evaluation of other expressions that contain them. Applications and sequences (begins) benefit most.
