Function focusedAndNotIgnored

profile/filter.go:233–248

focusedAndNotIgnored looks up a slice of ids against a map of focused/ignored locations. The map only contains locations that are explicitly focused or ignored. Returns whether there is at least one focused location but no ignored locations.

(locs []*Location, m map[uint64]bool)

// explicitly focused or ignored. Returns whether there is at least
// one focused location but no ignored locations.
func focusedAndNotIgnored(locs []*Location, m map[uint64]bool) bool {
	var f bool
	for _, loc := range locs {
		if focus, focusOrIgnore := m[loc.ID]; focusOrIgnore {
			if focus {
				// Found focused location. Must keep searching in case there
				// is an ignored one as well.
				f = true
			} else {
				// Found ignored location. Can return false right away.
				return false
			}
		}
	}
	return f
}
