Constructor Detail

PronounceableFSM

public PronounceableFSM(java.net.URL url,
                        boolean scanFromFront)
                 throws java.io.IOException

Constructs a PronounceableFSM with information in the given URL.

Parameters:

url - the URL that contains the FSM specification

scanFromFront - indicates whether this FSM should scan the input string from the front, or from the back

Throws:

java.io.IOException - if something went wrong

PronounceableFSM

public PronounceableFSM(int vocabularySize,
                        int[] transitions,
                        boolean scanFromFront)

Constructs a PronounceableFSM with the given attributes.

Parameters:

vocabularySize - the vocabulary size of the FSM

transitions - the transitions of the FSM

scanFromFront - indicates whether this FSM should scan the input string from the front, or from the back

Method Detail

accept

public boolean accept(java.lang.String inputString)

Checks to see if this finite state machine accepts the given input string.

Parameters:

inputString - the input string to be tested

Returns:

true if this FSM accepts, false if it rejects
