      use_previous_value: false,
      resolved_value: "ParameterValue",
    }

@!attribute [rw] parameter_key

@!attribute [rw] parameter_value

The input value associated with the parameter.
@return [String]

@!attribute [rw] use_previous_value

During a stack update, use the existing parameter value that the

not specify a parameter value.
@return [Boolean]

@!attribute [rw] resolved_value

field is returned only for [ `SSM` ][1] parameter types in the
