Tree::Persist::DB - The base class for DB plugins for Tree persistence

SYNOPSIS

See "SYNOPSIS" in Tree::Persist or scripts/xml.demo.pl for sample code.

DESCRIPTION

This class is the base class for the Tree::Persist::DB::* hierarchy, which provides DB plugins for Tree persistence through Tree::Persist.

PARAMETERS

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():

• type (required)

  For any DB::* plugin to be used, the type must be 'DB' (case-sensitive).

• dbh (required)

  This is the $dbh that is already connected to the right database and schema with the appropriate user. This is required.

• table (required)

  This is the table name that contains the tree. This is required.

METHODS

Tree::Persist::DB is a sub-class of Tree::Persist::Base, and inherits all its methods.

TODO

• Currently, the dbh and table options aren't checked for existence or validity.
