Function SchemaHasAdditionalProperties

pkg/codegen/utils.go:887–896

According to the spec, additionalProperties may be true, false, or a schema. If not present, true is implied. If it's a schema, true is implied. If it's false, no additional properties are allowed. We're going to act a little differently, in that if you want additionalProperties code to be generated

(schema *openapi3.Schema)

// you must specify an additionalProperties type
// If additionalProperties it true/false, this field will be non-nil.
func SchemaHasAdditionalProperties(schema *openapi3.Schema) bool {
	if schema.AdditionalProperties.Has != nil && *schema.AdditionalProperties.Has {
		return true
	}

	if schema.AdditionalProperties.Schema != nil {
		return true
	}
	return false
}

// PathToTypeName converts a path, like Object/field1/nestedField into a go
// type name.
