 use Config::Model ;
 # define configuration tree object

    name => "MyClass",
    element => [ 
        [qw/foo bar/] => { 
            type => 'leaf',
            value_type => 'string'
        },

 my $inst = $model->instance(root_class_name => 'MyClass' );
 my $root = $inst->config_root ;
 my $steps = 'baz:fr=bonjour baz:hr="dobar dan" foo="journalled"';
 $root->load( steps => $steps ) ;

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:

Search in all the items above

Methods

Parameters: "(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 elements. 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.
