ClusterInvoker (Apache Dubbo 3.0.0 API)

类型参数:

T -

所有超级接口:

Invoker<T>, org.apache.dubbo.common.Node

所有已知实现类:

AbstractClusterInvoker, AvailableClusterInvoker, BroadcastClusterInvoker, FailbackClusterInvoker, FailfastClusterInvoker, FailoverClusterInvoker, FailsafeClusterInvoker, FilterChainBuilder.ClusterFilterChainNode, ForkingClusterInvoker, MergeableClusterInvoker, MockClusterInvoker, ZoneAwareClusterInvoker
```
public interface ClusterInvoker<T>
extends Invoker<T>
```
This is the final Invoker type referenced by the RPC proxy on Consumer side.
A ClusterInvoker holds a group of normal invokers, stored in a Directory, mapping to one Registry. The ClusterInvoker implementation usually provides LB or HA policies, like FailoverClusterInvoker.
In multi-registry subscription scenario, the final ClusterInvoker will referr to several sub ClusterInvokers, with each sub ClusterInvoker representing one Registry. Take ZoneAwareClusterInvoker as an example, it is specially customized for multi-registry use cases: first, pick up one ClusterInvoker, then do LB inside the chose ClusterInvoker.
