Class SimpleInputDataSetConfigurator

java.lang.Object

oracle.spatial.hadoop.vector.data.conf.SimpleInputDataSetConfigurator

All Implemented Interfaces:

DataSetConfigurator<AbstractInputDataSet>, InputDataSetConfigurator

Direct Known Subclasses:

SimpleInputDataSetConfiguratorImpl, SimpleInputDataSetConfiguratorImpl

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

A generic configurator that accepts any instance of AbstractInputDataSet. It will perform the minimum setup, that is, it will only set the input format, record info provider, spatial configuration and data length. When used in a InputDataSetConfiguratorHandler chain, it must be placed at the end of the list of configurators, otherwise it will accept input data sets that may be better fitted by another configurator.
