the pronunciation for this word

isFinal

public boolean isFinal()

Determines if this is a final state

Specified by:

isFinal in interface SearchState

isWordStart

public boolean isWordStart()

Returns true if this LexTreeWordState indicates the start of a word. Returns false if this LexTreeWordState indicates the end of a word.

Specified by:

isWordStart in interface WordSearchState
