TranslatableException

Exceptions that provide translations should implement this interface.

The org.apache.causeway.applib.services.exceprecog.ExceptionRecognizer will automatically detect and use the translation. In addition, the integration testing support provides a rule ( ExceptionRecognizerTranslations ) that will exercise any thrown exceptions, ensuring tha the message is captured in the translations.po file so that it can be translated.

Members

getTranslatableMessage()

In the spirit of Exception#getLocalizedMessage() , but using TranslatableString instead.

If returns null , then Exception#getMessage() will be used as a fallback. This design allows the Causeway-provided RecoverableException and UnrecoverableException to provide constructors that accept a TranslatableString , but can be left as null for any existing code.
