Method SetErrorHandler

macro/macros.go:672–680

(fnHandler interface{})

// func(ctx iris.Context, paramIndex int, err error). It calls
// the Macro.HandleError method for each of the "ms" entries.
func (ms *Macros) SetErrorHandler(fnHandler interface{}) {
	for _, m := range *ms {
		if m == nil {
			continue
		}

		m.HandleError(fnHandler)
	}
