Klasse CrossValidationPartitioner.TrainingSampleStream<E>

java.lang.Object

opennlp.tools.util.eval.CrossValidationPartitioner.TrainingSampleStream<E>

Typparameter:

E - The generic type of samples.

Alle implementierten Schnittstellen:

AutoCloseable, ObjectStream<E>

Umschließende Klasse:

CrossValidationPartitioner<E>

public static class CrossValidationPartitioner.TrainingSampleStream<E>
extends Object
implements ObjectStream<E>

The CrossValidationPartitioner.TrainingSampleStream which iterates over all training elements.

Note: After the CrossValidationPartitioner.TestSampleStream was obtained the CrossValidationPartitioner.TrainingSampleStream must not be used anymore, otherwise a IllegalStateException is thrown.

The streams must not be used anymore after the CrossValidationPartitioner was moved to one of next partitions. If they are called anyway an IllegalStateException is thrown.

Modifizierer und Typ	Methode	Beschreibung
void	close()	Closes the ObjectStream and releases all allocated resources.
ObjectStream<E>	getTestSampleStream()	Retrieves the ObjectStream over the test/evaluations elements and poisons this CrossValidationPartitioner.TrainingSampleStream.
E	read()	Returns the next ObjectStream object.

Methodendetails

read

public E read()
       throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Returns the next ObjectStream object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Angegeben von:

read in Schnittstelle ObjectStream<E>

Gibt zurück:

The next object or null to signal that the stream is exhausted.

Löst aus:

IOException - Thrown if there is an error during reading.

reset

public void reset()
           throws IOException

Resets the training sample. Use this if you need to collect things before training, for example, to collect induced abbreviations or create a POS Dictionary.

Angegeben von:

reset in Schnittstelle ObjectStream<E>

Löst aus:

IOException - Thrown if IO errors occurred.

IllegalStateException - Thrown if a non-consistent state occurred.

close

public void close()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called, it's not allowed to call ObjectStream.read() or ObjectStream.reset().

Angegeben von:

close in Schnittstelle AutoCloseable

Angegeben von:

close in Schnittstelle ObjectStream<E>

Löst aus:

IOException - Thrown if there is an error during closing the stream.

getTestSampleStream

public ObjectStream<E> getTestSampleStream()
                                    throws IOException

Retrieves the ObjectStream over the test/evaluations elements and poisons this CrossValidationPartitioner.TrainingSampleStream. From now on calls to the hasNext and next methods are forbidden and will raise an IllegalArgumentException.

Gibt zurück:

The test sample stream.

Löst aus:

IOException
