Enclosing class:

TextHelper

public static interface TextHelper.MessageComponents

Deliverer of messageFormat components.

An object of an implementing class might be used (instead of Object[]) as parameter args for messageFormat(StringBuilder dest, CharSequence pattern, Object args).

The effect is almost the same, with the possible advantages of

• hiding the array from manipulation, which would then have to be effected by clone (see )
• triggering the getting of the information pieces just or only when really needed.

Clearly the second point is the real "beauty" of the approach, as it allows the triggering of message element's updates in the moment when and only if needed.
