java.lang.Object org.terrier.structures.indexing.singlepass.hadoop.PositionAwareSplit<T>
T
- public class PositionAwareSplit<T extends org.apache.hadoop.mapred.InputSplit>
An InputSplit, i.e. a subset of the input data. Notably, this implementation knows which split it is in the overall job, this way we can restore the ordering of the input later.
