public class WhereClauseTokens

extends java.lang.Object

Class that validates and gives a rules table for building both ArrayFilter and ArraySQL classes. Having a separate class to do this makes for much easier testing. This class can be tested indpendent of all the many other objects it takes to build ArrayFilters and the array of data it returns can easily be eyeballed for accuracy. Without this class testing ArrayFilter would be much more difficult. *
