Method String

mock/mock.go:1085–1105

String gets the argument at the specified index. Panics if there is no argument, or if the argument is of the wrong type. If no index is provided, String() returns a complete string representation of the arguments.

(indexOrNil ...int)

// If no index is provided, String() returns a complete string representation
// of the arguments.
func (args Arguments) String(indexOrNil ...int) string {
	if len(indexOrNil) == 0 {
		// normal String() method - return a string representation of the args
		var argsStr []string
		for _, arg := range args {
			argsStr = append(argsStr, fmt.Sprintf("%T", arg)) // handles nil nicely
		}
		return strings.Join(argsStr, ",")
	} else if len(indexOrNil) == 1 {
		// Index has been specified - get the argument at that index
		index := indexOrNil[0]
		var s string
		var ok bool
		if s, ok = args.Get(index).(string); !ok {
			panic(fmt.Sprintf("assert: arguments: String(%d) failed because object wasn't correct type: %s", index, args.Get(index)))
		}
		return s
	}

	panic(fmt.Sprintf("assert: arguments: Wrong number of arguments passed to String.  Must be 0 or 1, not %d", len(indexOrNil)))

// Int gets the argument at the specified index. Panics if there is no argument, or
// if the argument is of the wrong type.
