类 NodeRPCConnection

  • 直接已知子类:
    ServiceEndpoint
    public abstract class NodeRPCConnection
extends java.lang.Object
    Network connection for accessing hive node with restful APIs.

    The access token management is required for the sub-class implicitly.

    For file uploading, direct connection need be created for uploading stream.

                    HttpURLConnection urlConnection = connection.openConnection(FilesAPI.API_UPLOAD + path);
                OutputStream outputStream = new UploadOutputStream(urlConnection, urlConnection.getOutputStream());

    For other APIs, please directly create the relating service.

                    FilesAPI filesAPI = connection.createService(FilesAPI.class, true);
                String hashCode = filesAPI.getHash(path).execute().body().getHash();
