DESCRIPTION
This class provides a way to search the content of a configuration tree. Given a keyword or a pattern, the search method scans the tree to find a value, a description or anything that match the given pattern (or keyword).
Constructor
new (type => [ value | description ... ] )
Creates a new searcher object. The type
parameter can be:
Methods
search(keyword)
Search the keyword or pattern in the tree. The search is done in a case insensitive manner. Returns a list of path pointing to the matching tree element. See "grab" in Config::Model::Role::Grab for details on the path syntax.
BUGS
Creating a class with just one search method may be overkill. OTOH, it may be extended later to provide iterative search.
