SYNOPSIS

	use Meta::OpenFrame::Slot::Types qw();
	my($object)=Meta::OpenFrame::Slot::Types->new();
	my($result)=$object->method();

DESCRIPTION

Top

This class is should be able to do all the things that the regular OpenFrame::Slot::Images and OpenFrame::Slot::HTML. There is no real difference between the two. In addition, this class does Aegis type translations for the URLs if needed.

Most of the code here is just an adjustment of the OpenFrame::Slot::HTML code.

In order to understand what this class works and to a greater extent what it does you must be familiar with the OpenFrame framework.

The code here is for OpenFrame 2.x.

FUNCTIONS

FUNCTION DOCUMENTATION

Top

BEGIN()

Setup method to setup a Meta::File::MMagic object we need and it's cache.

what()

This method returns what this slot is supposed to return (a response).

action($$$)

This method actually does all the work.

TEST($)

This is a testing suite for the Meta::OpenFrame::Slot::Types module. This test is should be run by a higher level management system at integration or release time or just as a regular routine to check that all is well.
