All Implemented Interfaces:

Closable, INode, ISource, java.io.Serializable

public class GraphDataSource<T>
extends BaseSource

This class is responsible for partition the datapoints which is based on the task parallelism value. This class may use either the "LocalFixedInputPartitioner" or "LocalTextInputPartitioner" to partition the datapoints. Finally, write the partitioned datapoints into their respective edges.
