Hi,
I meant to write "start" method instead of "load". In a CTK plugin, you
need to use "start" and "stop", in a CppMicroServices module "load" and
"unload". You could mix both, but unless you are really familiar with
that subject, I would advise against it.
Best,
Sascha

I can see load methind in Module Activator here:
https://github.com/samsmu/MITK/blob/develop/Core/CppMicroServices/core/include/usModuleActivator.h
However with Plugin Activator I only have start and stop:
https://github.com/commontk/CTK/blob/master/Libs/PluginFramework/ctkPluginActivator.h
Can I use this Load methid inside plugin?

Hi,
I think it depends how the "tool plugin" can be distinguished from
other plugins:
Approaches where the plugin needs to be loaded and it actively
"registers something"
1. The tool plugin actively calls a singletone method of some other
plugin. If you want that call to happen at the earliest time possible,
you can either use the constructor of a file-scoped static object or
put the call in the plugin's activator load method.
2. The tool plugin makes use of the service registry and registers a
service object in its activator load method. The hypervisor plugin
would just track such services using the service registry.
Both approaches require the tool plugin to depend on some other entity
(the hypervisors singleton method or the service interface class).
For an enumeration of tool plug-ins, they probably do not need to be
loaded. They could be tracked by relying on meta data added to the
plug-ins. I assume you are working with CTK plugins (you can use
similar techniques with CppMicroServices modules)
- Add meta data to your plugin by modifying the manifest_headers.cmake
file and adding a new new line, e.g. "set(Provides-Tools 1)".
- The hypervisor plugin instantiates a ctkPluginTracker [1] which is
notified if new plugins are installed or change state. It can then use
the ctkPlugin::getHeaders() [2] method to check if the plugin contains
the "Provides-Tools" header.
Depending on your needs the above scheme can get more elaborate and
provide more information via meta data or embedded resources.
Best,
Sascha

Hello
I'm creating plugin which should know the list of available tools
plugins.
The idea was that those plugins during application loading will
call singletone method of hypervisor plugin.
So I wanted to know if that is possible to have method inside
plugins to be called during Application startup.
Thank you

Hi,
it's hard to give you proper advice without exactly knowing what
you are trying to achieve. You cant obviously call a function from
a plug-in until its shared library is loaded.
There are different hooks, listeners, etc. but without knowing
your use case I could just guess...
Cheers,
Sascha

Hello.
I need to make some action by some plugin after it's loading.
Not when I activate it. Before Activator loading.
Just when MITK itself starts it enumerates available plugins
and in that time I need to call some function iside that plugin.
Thank you.
