Constructor Details

#initialize(params, headers, operation, definitions, strong: false) ⇒ Parameters

Creates a new instance that wraps params according to operation. References are resolved to API components in definitions.

If strong is true+ parameters that can be mapped are accepted only. That means that the instance created is invalid if params contains any parameters that can’t be mapped to a parameter or a request body property of operation.
