@ExperimentalApi("https://github.com/grpc/grpc-java/issues/4159")
public abstract class NameResolverProvider
extends NameResolver.Factory
```
Provider of name resolvers for name agnostic consumption.
Implementations should not throw. If they do, it may interrupt class loading. If exceptions may reasonably occur for implementation-specific reasons, implementations should generally handle the exception gracefully and return false from isAvailable().

```
protected abstract boolean isAvailable()

    Whether this provider is available for use, taking the current environment into consideration. If false, no other methods are safe to be called.

  - priority
```
protected abstract int priority()
```
    A priority, from 0 to 10 that this provider should be used, taking the current environment into consideration. 5 should be considered the default, and then tweaked based on environment detection. A priority of 0 does not imply that the provider wouldn't work; just that it should be last in line.
