fElemMap	back to summary
private Object[] fElemMap This is the map of unique input symbol elements to indices into each state's per-input symbol transition table entry.

private int[][] fTransTable This is the transition table that is the main by product of all of the effort here. It is an array of arrays of ints. The first dimension is the number of states we end up with in the DFA. The second dimensions is the number of unique elements in the content model (fElemMapSize). Each entry in the second dimension indicates the new state given that input for the first dimension's start state. The fElemMap array handles mapping from element indexes to positions in the second dimension of the transition table.
