java.lang.Object

oracle.spatial.hadoop.vector.data.conf.MultiInputDataSetConfigurator

All Implemented Interfaces:

DataSetConfigurator<AbstractInputDataSet>, InputDataSetConfigurator

Direct Known Subclasses:

MultiInputDataSetConfiguratorImpl, MultiInputDataSetConfiguratorImpl

public abstract class MultiInputDataSetConfigurator
extends java.lang.Object
implements InputDataSetConfigurator

A configurator for data sets of type MultiInputDataSet. An instance of this class depends on an internal InputDataSetConfiguratorHandler which is passed at creation time and is used to eventually configure the data sets conatined in the MultiInputDataSet instance.
