Summary : Handle data in a hierarchical structure
|
Description :
the Data::Hierarchy manpage provides a simple interface for manipulating inheritable data attached to a hierarchical environment (like a filesystem).
One use of the Data::Hierarchy manpage 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.
Paths in a hierarchy are referred to in a Unix-like syntax; \'\"/\"\' is the root \"directory\". (You can specify a different separator character than the slash when you construct a Data::Hierarchy object.) With the exception of the root path, paths should never contain trailing slashes. You can associate properties, which are arbitrary name/value pairs, with any path. (Properties cannot contain the undefined value.) By default, properties are inherited by child paths: thus, if you store some data at \'/some/path\':
$tree->store(\'/some/path\', {color => \'red\'});
you can fetch it again at a \'/some/path/below/that\':
print $tree->get(\'/some/path/below/that\')->{\'color\'};
On the other hand, properties whose names begin with dots are uninherited, or \"sticky\":
$tree->store(\'/some/path\', {\'.color\' => \'blue\'}); print $tree->get(\'/some/path\')->{\'.color\'}; # prints blue print $tree->get(\'/some/path/below/that\')->{\'.color\'}; # undefined
Note that you do not need to (and in fact, cannot) explicitly add \"files\" or \"directories\" to the hierarchy; you simply add and delete properties to paths.
