Class InterpretationIndex

java.lang.Object
  |
  +--edu.mit.sketch.system.InterpretationIndex

public class InterpretationIndex

extends Object

A collection of all the items that need to be displayed. The interpretation index contains both the original strokes and links to their interpretations. It can get more complicated if necessary, for example, to communicate conflicts in the interpretations to the UI who can ask the user to help the system resolve these conflicts. Change or extend this class to do that.
