.. py:class:: NodeRPC(*args, **kwargs)

   Bases: :class:`grapheneapi.api.Api`

   .. autoapi-inheritance-diagram:: vizapi.noderpc.NodeRPC
      :parts: 1
:private-bases:
   Redefine graphene Api class.

   Class wraps communications with API nodes via proxying requests to lower-level :py:class:`Rpc` class and it's
   implementations :py:class:`Websocket` and :py:class:`Http`.

   To enable RPC debugging:

   .. code-block:: python

       log = logging.getLogger('vizapi')
       log.setLevel(logging.DEBUG)
       log.addHandler(logging.StreamHandler())

   .. method:: post_process_exception(self, error: Exception)


      Process error response and raise proper exception.

      Called from :py:meth:`__getattr__`, which catches RPCError exception which raised by
      :py:meth:`Rpc.parse_response` in Rpc class.

      :param error: exception


   .. method:: updated_connection(self)



   .. method:: get_network(self)


      Cache connected network info.

      This avoids multiple calls of self.get_config()


   .. method:: _get_network(self)


      Identify the connected network.

      This call returns a dictionary with keys chain_id, core_symbol and prefix



.. py:class:: Rpc(*args, **kwargs)

   Bases: :class:`grapheneapi.rpc.Rpc`

   .. autoapi-inheritance-diagram:: vizapi.noderpc.Rpc
      :parts: 1
:private-bases:
   This class is responsible for making RPC queries.

   Original graphene chains (like Bitshares) uses api_id in "params", while Golos and VIZ uses api name here.

   .. method:: __getattr__(self, name)


      Map all methods to RPC calls and pass through the arguments.



.. py:class:: Websocket(*args, **kwargs)

   Bases: :class:`grapheneapi.websocket.Websocket`, :class:`vizapi.noderpc.Rpc`

   .. autoapi-inheritance-diagram:: vizapi.noderpc.Websocket
      :parts: 1
:private-bases:
   Interface to API node websocket endpoint.

   We have to override Websocket class because we need it to inherit from our own Rpc class.

   .. method:: __getattr__(self, name)


      Map all methods to RPC calls and pass through the arguments.



.. py:class:: Http(*args, **kwargs)

   Bases: :class:`grapheneapi.http.Http`, :class:`vizapi.noderpc.Rpc`

   .. autoapi-inheritance-diagram:: vizapi.noderpc.Http
      :parts: 1
:private-bases:
   Interface to API node http endpoint.

   We have to override Websocket class because we need it to inherit from our own Rpc class.

   .. method:: __getattr__(self, name)


      Map all methods to RPC calls and pass through the arguments.
