Class DataStreamer

java.lang.Object

edu.iu.dsc.tws.api.compute.nodes.BaseNode

edu.iu.dsc.tws.api.compute.nodes.BaseSource

edu.iu.dsc.tws.examples.ml.svm.streamer.DataStreamer

All Implemented Interfaces:

Closable, INode, ISource, java.io.Serializable

Deprecated.

This class is deprecated This is the DataStreamer for both batch and streaming mode In streaming mode a single data point is sent continously. But in the batch application an array of data points is sent once.

@Deprecated
