Package org.jwall.web.audit.filter Description

The filter package provides two simple classes/interfaces to construct filters: the AuditEventMatch interface and the AuditEventFilter class.

The AuditEventMatch interface encapsulates and atomic checker-component for checking a particular property of an event. Matches can range from simple property matches, e.g. comparing the Host header, to more sophisticated things like event-id lists.

The filter class usually combines several matches into one "filter rule" and is uses these matches to do the filtering. An event usually matches a filter instance, if all matches are fulfilled.
