PathToKeyFunction (deeplearning4j 1.0.0-beta7 API)

java.lang.Object
- org.datavec.spark.functions.pairdata.PathToKeyFunction

All Implemented Interfaces:

Serializable, org.apache.spark.api.java.function.PairFunction<scala.Tuple2<String,org.apache.spark.input.PortableDataStream>,String,scala.Tuple3<String,Integer,org.apache.spark.input.PortableDataStream>>
```
public class PathToKeyFunction
extends Object
implements org.apache.spark.api.java.function.PairFunction<scala.Tuple2<String,org.apache.spark.input.PortableDataStream>,String,scala.Tuple3<String,Integer,org.apache.spark.input.PortableDataStream>>
```
Given a Tuple2, where the first value is the full path, map this to a Tuple3 where the first value is a key (using a PathToKeyConverter), second is an index, and third is the original data stream
