NAME

Top

OpenFrame::WebApp::Segment::Template - abstract class for getting Templates from the store.

SYNOPSIS

Top

  # abstract class - cannot be used directly

  use base qw( OpenFrame::WebApp::Segment::Template );

  sub dispatch {
      ...
      my $template $self->get_template_from_store;
      ...
  }

DESCRIPTION

Top

The OpenFrame::WebApp::Segment::Template class provides a method for getting Template objects from the store.

This class inherits its interface from Pipeline::Segment. You must override dispatch() for it to do anything.

METHODS

Top

get_template_from_store

If the store is a Pipeline::Store::ISA, looks for a descendant of OpenFrame::WebApp::Template, otherwise looks for known OpenFrame::WebApp::Template->types().
