示例1: parseConstraints

func parseConstraints(result *[]*structs.Constraint, obj *hclobj.Object) error {
	for _, o := range obj.Elem(false) {
		var m map[string]interface{}
		if err := hcl.DecodeObject(&m, o); err != nil {
			return err
		}
		m["LTarget"] = m["attribute"]
		m["RTarget"] = m["value"]
		m["Operand"] = m["operator"]

		// Default constraint to being hard
		if _, ok := m["hard"]; !ok {
			m["hard"] = true
		}

		// Build the constraint
		var c structs.Constraint
		if err := mapstructure.WeakDecode(m, &c); err != nil {
			return err
		}
		if c.Operand == "" {
			c.Operand = "="
		}

		*result = append(*result, &c)
	}
