Method FromInterface

pkg/attributes/attributes.go:457–469

FromInterface allows completing the map of attributes from the given interface. The given interface, and can be any value that supports Json Marshaling and will be marshalled as a JSON object. This is especially useful to create attributes from well-known, but implementation- dependent Go structure

(structure interface{}, errorHolder *error)

// to receive any error that might have occured during the attributes
// decoding
func (attributes Attributes) FromInterface(structure interface{}, errorHolder *error) Attributes {
	newAttributes := Attributes{}
	completeJSON, err := json.Marshal(structure)
	if err != nil && errorHolder != nil {
		*errorHolder = err
	}

	err = json.Unmarshal(completeJSON, &newAttributes)
	for key, value := range newAttributes {
		attributes[key] = value
	}
	return attributes
}
