Method Detail

parseDataDefinition

protected void parseDataDefinition(StreamTokenizer streamTokenizer)
                            throws IOException

Parse a data definition.

This line is only parsed when we still have to find acceptIndex, and acceptValue.

Specified by:

parseDataDefinition in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

Throws:

FSMFormatException - when the data definition is illegal.

IOException - see StreamTokenizer.nextToken().

checkDataDefinitions

protected void checkDataDefinitions(StreamTokenizer streamTokenizer)

Checks the data definition by ensuring the index in the state vector containing acceptance information is defined.

Specified by:

checkDataDefinitions in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

Throws:

FSMFormatException - when the acceptance information could not be found.

parseStateVector

protected void parseStateVector(StreamTokenizer streamTokenizer)
                         throws IOException

Parse a state vector.

This method will only search for whether the state is accepting or not. The state index will be equal to the current AbstractFSMParser.getPartLineNumber().

Specified by:

parseStateVector in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

Throws:

FSMFormatException - when the current line is an illegal state vector.

IOException - see StreamTokenizer.nextToken().

checkStateVectors

protected void checkStateVectors(StreamTokenizer streamTokenizer)

Does nothing.

Specified by:

checkStateVectors in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

parseTransition

protected void parseTransition(StreamTokenizer streamTokenizer)
                        throws IOException

Parse a transition by searching the current line for the source state, target state and the input.

Specified by:

parseTransition in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

Throws:

FSMFormatException - when the current line is an illegal transition.

IOException - see StreamTokenizer.nextToken().

checkTransitions

protected void checkTransitions(StreamTokenizer streamTokenizer)

Do nothing.

Specified by:

checkTransitions in class AbstractFSMParser<I>

Parameters:

streamTokenizer - tokenizer containing the input

readModel

public CompactDFA<I> readModel(InputStream is)
                        throws IOException

Description copied from interface: ModelDeserializer

Reads the contents from the given input stream and de-serializes it into a model instance.

Note: the input stream will not be closed.

Specified by:

readModel in interface ModelDeserializer<CompactDFA<I>>

Parameters:

is - the input stream to read data from

Returns:

the de-serialized model

Throws:

IOException - if an error occurred while reading from the stream

getParser

public static <I> FSM2DFAParser<I> getParser(@Nullable Collection<? extends I> targetInputs,
                                             Function<String,I> inputParser,
                                             String acceptingDataVariableName,
                                             String acceptingDataValue)

getParser

public static <I> FSM2DFAParser<I> getParser(Function<String,I> inputParser,
                                             String acceptingDataVariableName,
                                             String acceptingDataValue)
