Resolver types used by the components.
| Enumerator | |
|---|---|
| kGetaddrinfo | resolve hosts using blocking getaddrinfo call |
| kAsync | use non-blocking resolver |

| clients::dns::Resolver * clients::dns::GetResolverPtr | ( | const components::ComponentConfig & | config, |
| const components::ComponentContext & | context, | ||
| ResolverType | default_type = ResolverType::kAsync ) |
Returns pointer to asynchronous resolver interface if required by config or nullptr for getaddrinfo
| InvalidConfigException | on unknown resolver type in config |
