Akregator::Backend::Category
a convenience class to handle categories in the backend
Definition: feedstorage.h:40
Akregator::Backend::Category::operator==
bool operator==(const Category &other) const
two categories are equal when scheme and term are equal, name is ignored
Definition: feedstorage.h:49
Akregator::Backend::Category::operator<
bool operator<(const Category &other) const
we need this for TQMaps
