Method Details
-
read
Description copied from interface:ObjectStreamReturns the nextObjectStreamobject. Calling this method repeatedly until it returnsnullwill return each object from the underlying source exactly once.- Specified by:
readin interfaceObjectStream<Sequence<LemmaSample>>- Returns:
- The next object or
nullto signal that the stream is exhausted. - Throws:
IOException- Thrown if there is an error during reading.
-
updateContext
Description copied from interface:SequenceStreamCreates a new event array based on the outcomes predicted by the specified parameters for the specifiedSequence.- Specified by:
updateContextin interfaceSequenceStream<LemmaSample>- Parameters:
sequence- TheSequenceto be evaluated.model- Themodelto use.- Returns:
- The resulting
Eventarray.
-
reset
Description copied from interface:ObjectStreamRepositions 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.
- Specified by:
resetin interfaceObjectStream<Sequence<LemmaSample>>- Throws:
IOException- Thrown if there is an error during resetting the stream.UnsupportedOperationException- Thrown if thereset()is not supported. By default, this is the case.
-
close
Description copied from interface:ObjectStreamCloses theObjectStreamand releases all allocated resources. After close was called, it's not allowed to callObjectStream.read()orObjectStream.reset().- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceObjectStream<Sequence<LemmaSample>>- Throws:
IOException- Thrown if there is an error during closing the stream.
