Class ParticipantsInScope

java.lang.Object
  parsedtree.ParticipantsInScope

public class ParticipantsInScope

extends java.lang.Object

This class keeps a list of names that are valid participants. At the start of a figure, it is set to the list of participants to the figure. (The local names are stored). As units are formed and disbanded, these are added and removed from this list. Thus at any point of time it contains the list of names that are valid participants in moves and figures.

People are still in the list even if they are currently in a unit, so technically they are not valid participants. However such errors are detected by the caller and this gives a better error message.
