}
sub lookup

}
sub expand
{
        my ($self) = @_;

DESCRIPTION

This is a virtual base class for HTML::Transmorgify variables that are accessed by HTML::Transmorgify::Metatags directives.

Variables can have multiple components to their names, separated with dot (.) and the components will be looked up one-by-one.

There are four methods that need to be implemented:

text()

Convert the entire object to a text string.

lookup($key)

Look up a value within the object. The return value can be a scalar, a hash ref, an array ref, or another HTML::Transmorgify::ObjectGlue-based object.

expand

Return a list of the sub-objects in the object. This is used by HTML::Transmorgify::Metatags for iterating over the sub-objects with <foreach>.

set
