Data::Hierarchy 0.34

Data::Hierarchy is a Perl module to handle data in a hierarchical structure.

SYNOPSIS

 my $tree = Data::Hierarchy->new();
 $tree->store ('/', {access => 'all'});
 $tree->store ('/private', {access => 'auth',
 '.note' => 'this is private});

 $info = $tree->get ('/private/somewhere/deep');

 # return actual data points in list context
 ($info, @fromwhere) = $tree->get ('/private/somewhere/deep');

 my @items = $tree->find ('/', {access => qr/.*/});

 # override all children
 $tree->store ('/', {'.note' => undef}, {override_sticky_descendents => 1});

Data::Hierarchy provides a simple interface for manipulating inheritable data attached to a hierarchical environment (like a filesystem).

One use of Data::Hierarchy is to allow an application to annotate paths in a real filesystem in a single compact data structure. However, the hierarchy does not actually need to correspond to an actual filesystem.
