Constructor Detail

ByteSequenceIterator

public ByteSequenceIterator(FSA fsa)

Create an instance of the iterator iterating over all automaton sequences.

Parameters:

fsa - The automaton to iterate over.

ByteSequenceIterator

public ByteSequenceIterator(FSA fsa,
                    int node)

Create an instance of the iterator for a given node.

Parameters:

fsa - The automaton to iterate over.

node - The starting node's identifier (can be the FSA.getRootNode()).

Method Detail

restartFrom

public ByteSequenceIterator restartFrom(int node)

Restart walking from node. Allows iterator reuse.

Parameters:

node - Restart the iterator from node.

Returns:

Returns this for call chaining.

hasNext

public boolean hasNext()

Returns true if there are still elements in this iterator.

Specified by:

hasNext in interface java.util.Iterator<java.nio.ByteBuffer>

next

public java.nio.ByteBuffer next()

Specified by:

next in interface java.util.Iterator<java.nio.ByteBuffer>

Returns:

Returns a ByteBuffer with the sequence corresponding to the next final state in the automaton.

remove

public void remove()

Not implemented in this iterator.

Specified by:

remove in interface java.util.Iterator<java.nio.ByteBuffer>
