Class MessagesImpl

java.lang.Object

play.i18n.MessagesImpl

All Implemented Interfaces:

play.api.i18n.MessagesProvider, Messages

public class MessagesImpl
extends Object
implements Messages

This class implements the Messages interface.

This class serves two purposes. One is for backwards compatibility, it serves the old static API for accessing messages. The other is a new API, which carries an inject messages, and a selected language.

The methods for looking up messages on the old API are called get, on the new API, they are called at. In Play 3.0, when we remove the old API, we may alias the at methods to the get names.
