How to override the mod_k2_tools helper function?

Question

I'm trying to understand how to override the helper.php found in /joomla_site/modules/mod_k2_tools because it is not a component but a module, and it is not the controller, because the controller is mod_k2_tools.php.

If that above is right, then I have no idea how to override the helper.php to change the functionily of the K2 calendar.

I read How to override core classes, and followed the example How to override the component mvc from the Joomla! core. However, nothing changed.

Before started with the override, I directly modified the /joomla_site/modules/mod_k2_tools/helper.php to get the functionality I was looking for and as it worked, I decided starting with the override issue.

In the plugin that we must create, in the line

if('com_content' == JRequest::getCMD('option') && !$app->isAdmin())

the com_content makes reference to the content component, so, it should be replace by the 'mod_k2_tools` string, right?

Can the helper.php be overridden? Any guidance on what to check or pointing to a new beginning?

I'm using Joomla! 2.5.27, and K2 2.6.8.

Firstly, not everything can be overriden, sometimes you can just create your own mod_myk2_tools.

Secondly, a feature can be overriden only if it is instantiated with a dynamic loading mechanism. This kind of technique checks if a resourse is already loaded before loading, allowing to load it before. In mod_k2_tools module, the helper is just included in this basic PHP way: "require_once (dirname(FILE).DS.'helper.php');". It is not possible to override it.
