Class FSA5Serializer

java.lang.Object

morfologik.fsa.FSA5Serializer

All Implemented Interfaces:

FSASerializer

public final class FSA5Serializer
extends java.lang.Object
implements FSASerializer

Serializes in-memory FSA graphs to a binary format compatible with Jan Daciuk's fsa's package FSA5 format.

It is possible to serialize the automaton with numbers required for perfect hashing. See withNumbers() method.

Method Detail

withNumbers

public FSA5Serializer withNumbers()

Serialize the automaton with the number of right-language sequences in each node. This is required to implement perfect hashing. The numbering also preserves the order of input sequences.

Specified by:

withNumbers in interface FSASerializer

Returns:

Returns the same object for easier call chaining.

withFiller

public FSA5Serializer withFiller(byte filler)

Supports built-in filler separator. Only if FSASerializer.getFlags() returns FSAFlags.SEPARATORS.

Specified by:

withFiller in interface FSASerializer

withAnnotationSeparator

public FSA5Serializer withAnnotationSeparator(byte annotationSeparator)

Supports built-in annotation separator. Only if FSASerializer.getFlags() returns FSAFlags.SEPARATORS.

Specified by:

withAnnotationSeparator in interface FSASerializer

withLogger

public FSASerializer withLogger(IMessageLogger logger)

Log extra messages during construction.

Specified by:

withLogger in interface FSASerializer

serialize

public <T extends java.io.OutputStream> T serialize(FSA fsa,
                                           T os)
                                         throws java.io.IOException

Serialize root state s to an output stream in FSA5 format.

Specified by:

serialize in interface FSASerializer

Returns:

Returns os for chaining.

Throws:

java.io.IOException

getFlags

public java.util.Set<FSAFlags> getFlags()

Return supported flags.

Specified by:

getFlags in interface FSASerializer
