Constructor Details

#initialize(param_symbol, supported_accessor, available_accessor, get_accessor, set_accessor, start_condition: nil, preprocess_value: nil, check_equality: method(:default_check_equality), check_availability: method(:default_check_availability), end_condition: nil) ⇒ APIGroup

Create API group object.

Parameters:

  • param_symbol (Symbol) —

    API Group name

  • supported_accessor (Proc) —

    Get the supported values from getSupportedXXX raw response.

  • available_accessor (Proc) —

    Get the available values from getAvailableXXX raw response.

  • get_accessor (Proc) —

    Get the current value from getXXX raw response.

  • set_accessor (Proc) —

    Set given value to setXXX request.

  • start_condition (Proc) (defaults to: nil) —

    Wait until given condition before accessing parameter.

  • preprocess_value (Proc) (defaults to: nil) —

    Convert given value and arguments into the internal format to be compared.

  • check_equality (Proc) (defaults to: method(:default_check_equality)) —

    Compare given value and current one to judge whether new value should be set or not.

  • check_availability (Proc) (defaults to: method(:default_check_availability)) —

    Compare given value and avialable ones to judge whether new value is available.

  • end_condition (Proc) (defaults to: nil) —

    Wait until given condition after changing parameter.
