Class WritableDataSetWrapper

java.lang.Object

org.das2.qds.AbstractDataSet

org.das2.qds.WritableDataSetWrapper

All Implemented Interfaces:

MutablePropertyDataSet, QDataSet, WritableDataSet

public class WritableDataSetWrapper
extends AbstractDataSet
implements WritableDataSet

Jython needs all datasets to be writable, and this provides the write capability while avoiding unnecessary copies when the dataset is never mutated.
