Context.Key (grpc-all 1.58.0 API)

java.lang.Object
- io.grpc.Context.Key<T>

Enclosing class:

Context
```
public static final class Context.Key<T>
extends java.lang.Object
```
Key for indexing values stored in a context. Keys use reference equality and Context does not provide a mechanism to loop over Keys. This means there is no way to access a Key's value from a Context without having access to the Key instance itself. This allows strong control over what code can get/set a key in the Context. For example, you might manage access to Key similar to a ThreadLocal using Java visibility (private/protected). Generally Keys are stored in static fields.
