Class Method Details

.parse(string, default_v11 = :wd, serializer = JsonRpcObjects::default_serializer) ⇒ Object

Parses JSON-RPC string for response and uses differential heuristic for detecting the right class.

Be warn, it’s impossible to distinguish JSON-RPC 1.1 Alt and WD if there aren’t error. So responsens without it are detected as WD. Set the default 1.1 version by second argument.

Parameters:

  • string (String) —

    JSON string for parse

  • default_v11 (:wd, :alt) (defaults to: :wd) —

    type of the eventually returned 1.1 object

  • serializer (JsonRpcObjects::Serializer) (defaults to: JsonRpcObjects::default_serializer) —

    instance of serializer class

Since:

  • 0.2.0
