5 Cache Iterators - Iterators for navigating the cache structure
6
7 The iterators all provides ++,==,!=,->,* and end for their type.
8 The end function can be used to tell if the list has been fully
9 traversed.
10
11 Unlike STL iterators these contain helper functions to access the data
12 that is being iterated over. This is because the data structures can't
13 be formed in a manner that is intuitive to use and also mmapable.
14
15 For each variable in the target structure that would need a translation
16 to be accessed correctly a translating function of the same name is
17 present in the iterator. If applicable the translating function will
18 return an iterator.
19
20 The DepIterator can iterate over two lists, a list of 'version depends'
21 or a list of 'package reverse depends'. The type is determined by the
22 structure passed to the constructor, which should be the structure
6c139d6e
AL
23 that has the depends pointer as a member. The provide iterator has the
24 same system.
