Method AddAt

core/fields_list.go:129–141

AddAt is the same as Add but insert/move the fields at the specific position. If pos < 0, then this method acts the same as calling Add. If pos > FieldsList total items, then the specified fields are inserted/moved at the end of the list.

(pos int, fields ...Field)

//
// If pos > FieldsList total items, then the specified fields are inserted/moved at the end of the list.
func (l *FieldsList) AddAt(pos int, fields ...Field) {
	total := len(*l)

	for i, f := range fields {
		if pos < 0 {
			l.add(-1, f)
		} else if pos > total {
			l.add(total+i, f)
		} else {
			l.add(pos+i, f)
		}
	}
}

// AddMarshaledJSON parses the provided raw json data and adds the
// found fields into the current list (following the same rule as the Add method).
