Parameters:
way - the Character associated with the Cell holding the desired command
Returns:
the command

getCnt

public int getCnt(Character way)
Return the number of patch commands were in the Cell associated with the given Character before the Trie containing this Row was reduced.

Parameters:
way - the Character associated with the desired Cell
Returns:
the number of patch commands before reduction

getRef

public int getRef(Character way)
Return the reference to the next Row in the Cell associated with the given Character.

Parameters:
