Class ActionBinding

java.lang.Object
edu.tufts.hrilab.action.ActionBinding
All Implemented Interfaces:
Serializable, Cloneable
public class ActionBinding extends Object implements Cloneable, Serializable
An ActionBinding is an association between a variable name and a value. This is really a variable, insofar as it can be uninitialized (i.e., have no value associated with it). An uninitialized binding consists of a name and a type, and may later be bound to an object.
