Function MakeHandler

macro/handler/handler.go:63–81

MakeHandler creates and returns a handler from a macro template, the handler evaluates each of the parameters if necessary at all. If the template does not contain any dynamic attributes and a special handler is NOT required then it returns a nil handler.

(tmpl macro.Template)

// If the template does not contain any dynamic attributes and a special handler is NOT required
// then it returns a nil handler.
func MakeHandler(tmpl macro.Template) context.Handler {
	filter := MakeFilter(tmpl)

	return func(ctx *context.Context) {
		if !filter(ctx) {
			if ctx.GetCurrentRoute().StatusErrorCode() == ctx.GetStatusCode() {
				ctx.Next()
			} else {
				ctx.StopExecution()
			}

			return
		}

		// if all passed or the next is the registered error handler to handle this status code,
		// just continue.
		ctx.Next()
	}
}

// MakeFilter returns a Filter which reports whether a specific macro template
// and its parameters pass the serve-time validation.
