      de.ls5.jlearn.batchoracles.LengthSortBatchOracle

All Implemented Interfaces:

BatchOracle, Oracle, Serializable

public class LengthSortBatchOracle
extends AbstractBatchOracle

A BatchOracle that sorts queries according to length into descending order. This means that, e.g., all queries being prefixes of other queries will be asked after the queries they are prefixes of. This increases the chance of a cache hit.
