FilterEntry Class Reference

A simple ListItem derived class to allow a list of filters to be maintained - the list holds all the filters that claim to understand a particular file (see FilterFamily). It is not derived from the Filter class itself because although the Filter class is derived from ListItem too, we want to store a list of pointers to existing filters, rather than actual instances of the Filter class. For each entry, a 'compatibility rating' is held, to allow the FilterFamily class (the client of this class) to choose the most compatible filter from the list. More...
