Creates and manages NameResolvers so that each EventExecutor has its own resolver instance.

Field Summary

private final Map<EventExecutor, AddressResolver<T>>	resolvers Note that we do not use a `ConcurrentMap` here because it is usually expensive to instantiate a resolver.

getResolver	back to summary
public AddressResolver<T> getResolver(final EventExecutor executor) Returns the `AddressResolver` associated with the specified `EventExecutor`. If there's no associated resolver found, this method creates and returns a new resolver instance created by `newResolver(EventExecutor)` so that the new resolver is reused on another `#getResolver(EventExecutor)` call with the same `EventExecutor`.

newResolver	back to summary
protected abstract AddressResolver<T> newResolver(EventExecutor executor) throws Exception Invoked by `getResolver(EventExecutor)` to create a new `AddressResolver`.
