Method Detail

getGroupCount

public int getGroupCount()

getGroups

public int[] getGroups()

getGroup

getLookup

public int[] getLookup()

add

public void add(int ch)

add

public void add(boolean[] ccl)

add

public void add(short[] error)

All non-zero values are treated as a group. This function is for computing DFA compression error group.

Parameters:

error - an error vector

compute

private void compute()

Not a particularly efficient method to compute equivalent classes. It is quite memory consuming at present.
