Examples of Datastream

one.nio.serial.DataStream
opennlp.maxent.DataStream
A interface for objects which can deliver a stream of training data to be supplied to an EventStream. It is not necessary to use a DataStream in a Maxent application, but it can be used to support a wider variety of formats in which your training data can be held.
