POSSampleSequenceStream

public POSSampleSequenceStream(ObjectStream<POSSample> psi)

Creates a POSSampleSequenceStream with given samples using a DefaultPOSContextGenerator.

Parameter:

psi - The data stream of samples.

POSSampleSequenceStream

public POSSampleSequenceStream(ObjectStream<POSSample> psi,
 POSContextGenerator pcg)

Creates a POSSampleSequenceStream with given samples using a POSContextGenerator.

Parameter:

psi - The data stream of samples.

pcg - A POSContextGenerator which shall be used.

Methodendetails

updateContext

public Event[] updateContext(Sequence<POSSample> pss,
 AbstractModel model)

Beschreibung aus Schnittstelle kopiert: SequenceStream

Creates a new event array based on the outcomes predicted by the specified parameters for the specified Sequence.

Angegeben von:

updateContext in Schnittstelle SequenceStream<POSSample>

Parameter:

pss - The Sequence to be evaluated.

model - The model to use.

Gibt zurück:

The resulting Event array.

read

public Sequence<POSSample> 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<Sequence<POSSample>>

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,
UnsupportedOperationException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required.

The implementation of this method is optional.

Angegeben von:

reset in Schnittstelle ObjectStream<Sequence<POSSample>>

Löst aus:

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

UnsupportedOperationException - Thrown if the reset() is not supported. By default, this is the case.

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<Sequence<POSSample>>

Löst aus:

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