9 ### lazy load author/module trees ###
10
11 $cb->_author_tree;
12 $cb->_module_tree;
13
15 CPANPLUS::Internals::Source controls the updating of source files and
16 the parsing of them into usable module/author trees to be used by
17 "CPANPLUS".
18
19 Functions exist to check if source files are still "good to use" as
20 well as update them, and then parse them.
21
22 The flow looks like this:
23
24 $cb->_author_tree || $cb->_module_tree
25 $cb->_check_trees
26 $cb->__check_uptodate
27 $cb->_update_source
28 $cb->__update_custom_module_sources
29 $cb->__update_custom_module_source
30 $cb->_build_trees
31 ### engine methods
32 { $cb->_init_trees;
33 $cb->_standard_trees_completed
34 $cb->_custom_trees_completed
35 }
36 $cb->__create_author_tree
37 ### engine methods
38 { $cb->_add_author_object }
39 $cb->__create_module_tree
40 $cb->__create_dslip_tree
41 ### engine methods
42 { $cb->_add_module_object }
43 $cb->__create_custom_module_entries
44
45 $cb->_dslip_defs
