ConstantsWithLookup (Google Web Toolkit Javadoc)

All Superinterfaces:

Constants, Localizable, LocalizableResource
```
public interface ConstantsWithLookup
extends Constants
```
Like Constants, a tag interface that facilitates locale-sensitive, compile-time binding of constant values supplied from properties files with the added ability to look up constants at runtime with a string key.
ConstantsWithLookup extends Constants and is identical in behavior, adding only a family of special-purpose lookup methods such as getString(String).

It is generally preferable to extend Constants rather than ConstantsWithLookup because ConstantsWithLookup forces all constants to be retained in the compiled script, preventing the GWT compiler from pruning unused constant accessors.

Required Module
Modules that use this interface should inherit com.google.gwt.i18n.I18N.
```
<module>
  
  <inherits name="com.google.gwt.i18n.I18N"/>
  
</module>
```
Note
You should not directly implement this interface or interfaces derived from it since an implementation is generated automatically when message interfaces are created using GWT.create(Class).
