StreamKey (ExoPlayer library)

java.lang.Object
- com.google.android.exoplayer2.offline.StreamKey

All Implemented Interfaces:

Parcelable, Comparable<StreamKey>
```
public final class StreamKey
extends Object
implements Comparable<StreamKey>, Parcelable
```
A key for a subset of media which can be separately loaded (a "stream").
The stream key consists of a period index, a group index within the period and a track index within the group. The interpretation of these indices depends on the type of media for which the stream key is used.
