ObjectKey (library 4.14.2 API)

java.lang.Object
- com.bumptech.glide.signature.ObjectKey

All Implemented Interfaces:

Key
```
public final class ObjectKey
extends java.lang.Object
implements Key
```
Wraps an Object, delegating equals(Object) and hashCode() to the wrapped Object and providing the bytes of the result of the Object's toString() method to the MessageDigest in updateDiskCacheKey(java.security.MessageDigest).
The Object's toString() method must be unique and suitable for use as a disk cache key.
