/**
* The gRPC core public API.
*
* gRPC is based on a client-server model of remote procedure calls. A client creates a channel
* which is connected to a server. RPCs are initiated from the client and sent to the server which
* then responds back to the client. When the client and server are done sending messages, they half
* close their respective connections. The RPC is complete as soon as the server closes.
*
*
To send an RPC, first create a {@link com.alibaba.nacos.shaded.io.grpc.Channel} using {@link
* com.alibaba.nacos.shaded.io.grpc.ManagedChannelBuilder#forTarget}. When using auto generate Protobuf stubs, the stub class
* will have constructors for wrapping the channel. These include {@code newBlockingStub}, {@code
* newStub}, and {@code newFutureStub} which you can use based on your design. The stub is the
* primary way a client interacts with a server.
*
*
To receive RPCs, create a {@link com.alibaba.nacos.shaded.io.grpc.Server} using {@link com.alibaba.nacos.shaded.io.grpc.ServerBuilder#forPort}.
* The Protobuf stub will contain an abstract class called AbstractFoo, where Foo is the name of
* your service. Extend this class, and pass an instance of it to {@link
* com.alibaba.nacos.shaded.io.grpc.ServerBuilder#addService}. Once your server is built, call {@link com.alibaba.nacos.shaded.io.grpc.Server#start}
* to begin accepting RPCs.
*
*
Both Clients and Servers should use a custom {@link java.util.concurrent.Executor}. The gRPC
* runtime includes a default executor that eases testing and examples, but is not ideal for use in
* a production environment. See the associated documentation in the respective builders.
*
*
Clients and Servers can also be shutdown gracefully using the {@code shutdown} method. The API
* to conduct an orderly shutdown is modeled from the {@link java.util.concurrent.ExecutorService}.
*
*
gRPC also includes support for more advanced features, such as name resolution, load
* balancing, bidirectional streaming, health checking, and more. See the relative methods in the
* client and server builders.
*
*
Development of gRPC is done primary on Github at https://github.com/grpc/grpc-java, where the gRPC
* team welcomes contributions and bug reports. There is also a mailing list at grpc-io if you have questions about
* gRPC.
