|
|
* A string bundle.
|
|
*
|
|
* This object presents two APIs: a deprecated one that is equivalent to the API
|
|
* for the stringbundle XBL binding, to make it easy to switch from that binding
|
|
* to this module, and a new one that is simpler and easier to use.
|
|
*
|
|
* The benefit of this module over the XBL binding is that it can also be used
|
|
* in JavaScript modules and components, not only in chrome JS.
|
|
*
|
|
* To use this module, import it, create a new instance of StringBundle,
|
|
* and then use the instance's |get| and |getAll| methods to retrieve strings
|
|
* (you can get both plain and formatted strings with |get|):
|
|
*
|
|
* let strings =
|
|
* new StringBundle("chrome://example/locale/strings.properties");
|
|
* let foo = strings.get("foo");
|
|
* let barFormatted = strings.get("bar", [arg1, arg2]);
|
|
* for (let string of strings.getAll())
|
|
* dump (string.key + " = " + string.value + "\n");
|
|
*
|
|
* @param url {String}
|
|
* the URL of the string bundle
