Method Detail

init

public void init(SeqClassifierFlags flags)

Description copied from interface: DocumentReaderAndWriter

This will be called immediately after construction. It's easier having an init() method because DocumentReaderAndWriter objects are usually created using reflection.

Specified by:

init in interface DocumentReaderAndWriter<CoreLabel>

Parameters:

flags - Flags specifying behavior

getIterator

public java.util.Iterator<java.util.List<CoreLabel>> getIterator(java.io.Reader r)

Description copied from interface: IteratorFromReaderFactory

Return an iterator over the contents read from r.

Specified by:

getIterator in interface IteratorFromReaderFactory<java.util.List<CoreLabel>>

Parameters:

r - Where to read objects from

Returns:

An Iterator over the objects

printAnswers

public void printAnswers(java.util.List<CoreLabel> doc,
                         java.io.PrintWriter out)

Description copied from interface: DocumentReaderAndWriter

This method prints the output of the classifier to a PrintWriter.

Specified by:

printAnswers in interface DocumentReaderAndWriter<CoreLabel>

Parameters:

doc - The document which has answers (it has been classified)

out - Where to send the output
