Interface ValueTransformer
-
public interface ValueTransformer
Definition of an interface used by
ListDelimiterHandlerto perform additional transformations on behalf of a configuration when a property value is escaped.Some
Configurationimplementations require a special encoding of their property values before they get written on disk. In some constellations, e.g. when a property with multiple values is to be forced on a single line, this encoding has to be done together with the escaping of list delimiter characters - which is in the responsibility ofListDelimiterHandler.In order to allow a proper collaboration between the parties involved, this interface was introduced. A configuration object provides an implementation of
ValueTransformerand passes it to theListDelimiterHandlerwhen escaping of properties is needed. The delimiter handler can then call back to perform the additional encoding as its pleasure.- Since:
