      type - the type of the requested object
      name - the system name of the requested object
      data - JSON data set of attributes of the requested object
      request - the JSON request

      a JSON description of the requested object
      Throws:
      JsonException - if the named object does not exist or other error occurs
    • doPost

      public com.fasterxml.jackson.databind.JsonNode doPost(String type, String name, com.fasterxml.jackson.databind.JsonNode data, JsonRequest request) throws JsonException
      Description copied from class: JsonHttpService
      Respond to an HTTP POST request for the requested name.

      This method should throw a 400 Invalid Request error if the named object does not exist.

    • doSchema

      public com.fasterxml.jackson.databind.JsonNode doSchema(String type, boolean server, JsonRequest request) throws JsonException
      Description copied from class: JsonHttpService
      Get the JSON Schema for the data property of the requested type of JSON object. It is a invalid for implementations to not return a valid schema that clients can use to validate a request to or response from the JSON services.

      Note that a schema must be contained in a standard object as:

      {"type":"schema", "data":{"schema":<em>schema</em>, "server":boolean}}

      If using JsonHttpService.doSchema(String, boolean, String, String, int), an implementation can be as simple as: return doSchema(type, server, "path/to/client/schema.json", "path/to/server/schema.json", id);

      Specified by:
      doSchema in class JsonHttpService
      Parameters:
      type - the type for which a schema is requested
      server - true if the schema is for a message from the server; false if the schema is for a message from the client
      request - the JSON request
      Returns:
      a JSON Schema valid for the type
      Throws:
      JsonException - if an error occurs preparing schema; if type is is not a type handled by this service, this must be thrown with an error code of 500 and the localized message ERROR_UNKNOWN_TYPE
