edu.tufts.hrilab.action.EventSpec
All Implemented Interfaces:
Serializable
public final class EventSpec extends Object implements Serializable
An event specification is a description of a step (event) in an action script. Some events are realized as actions, and other events are controls (e.g. if, while). The EventSpec class is designed to parse the String that describes the step and provide simple accessors to the command (or control) and the list of arguments. This class is immutable.
