Method Get

pkg/attributes/attributes.go:193–207

Get allows returning the attribute with the given key as an interface. The underlying type of the returned interface depends on the JSON/YAML content of the attribute. It can be either a simple type like a string, a float64 or a bool, either a structured type like a map of interfaces or an array of

(key string, errorHolder *error)

// to receive any error that might have occurred during the attribute
// decoding
func (attributes Attributes) Get(key string, errorHolder *error) interface{} {
	if attribute, exists := attributes[key]; exists {
		container := &[]interface{}{}
		err := json.Unmarshal([]byte("[ "+string(attribute.Raw)+" ]"), container)
		if err != nil && errorHolder != nil {
			*errorHolder = err
		}
		if len(*container) > 0 {
			return (*container)[0]
		}
	} else if !exists && errorHolder != nil {
		*errorHolder = &KeyNotFoundError{Key: key}
	}
	return nil
}

// GetInto allows decoding the attribute with the given key
// into a given interface. The provided interface should be a pointer
