Tree::Persist::File - The base class for File plugins for Tree persistence
See "SYNOPSIS" in Tree::Persist or scripts/xml.demo.pl for sample code.
This class is a base class for the Tree::Persist::File::* hierarchy, which provides File plugins for Tree persistence.
Parameters are used in the call to "connect({%opts})" in Tree::Persist or "create_datastore({%opts})" in Tree::Persist.
In addition to any parameters required by its parent Tree::Persist::Base, the following parameters are used by connect() or create_datastore():
connect()
create_datastore()
class (optional)
This is the name of a user-supplied class for deflation/inflation.
The class parameter takes precedence over the type parameter.
class
type
If class is not provided, type is used, and defaults to 'File'. Then class is determined using:
$class = $type eq 'File' ? 'Tree::Persist::File::XML' : 'Tree::Persist::DB::SelfReferential';
See t/save_and_load.t for sample code.
filename (required)
This is the filename that will be used as the datastore.
type (optional)
For any File::* plugin to be used, the type must be 'File' (case-sensitive) unless a class is provided.
Tree::Persist::File is a sub-class of Tree::Persist::Base, and inherits all its methods.
Currently, the filename parameter isn't checked for validity or existence.
Please see the relevant section of Tree::Persist.
