DESCRIPTION

50       This class provides a way to search the content of a configuration
51       tree.  Given a keyword or a pattern, the search method scans the tree
52       to find a value, a description or anything that match the given pattern
53       (or keyword).
54

Constructor

56   new (type => [ value | description ... ] )
57       Creates a new searcher object. The "type" parameter can be:
58
59       element
60       value
61       key
62       summary
63       description
64       help
65       all Search in all the items above
66

Methods

68   search
69       Parameters: "(keyword)"
70
71       Search the keyword or pattern in the tree. The search is done in a case
72       insensitive manner. Returns a list of path pointing to the matching
73       tree elements. See "grab" in Config::Model::Role::Grab for details on
74       the path syntax.
75

BUGS

77       Creating a class with just one search method may be overkill. OTOH, it
78       may be extended later to provide iterative search.
