See the {@link hirondelle.web4j.BuildImpl} for important information on how this item is configured.
Almost all concrete implementations of this Abstract Base Class will need to implement only a single method - {@link #getWebAction()}. WEB4J provides a default implementation {@link RequestParserImpl}.
The role of this class is to view the request at a higher level than the underlying Servlet API. In particular, its services include :
File upload parameters are not returned by this class. Such parameters must be examined in an {@link Action}. The Servlet API has poor support for file upload parameters, and use of a third party tool is recommended.
The various toXXX methods are offered as a convenience for accessing String and String-like data. All such toXXX methods apply the filtering (and possible preprocessing) performed by {@link hirondelle.web4j.model.ConvertParam}.
