Class Context.Key<T>

java.lang.Object
io.grpc.Context.Key<T>
Enclosing class:
Context
public static final class Context.Key<T> extends 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.
