Global variables in Eclipse RCP

Question

how can i solve this:

I have user info in my main RCP plugin. All other plugins must also have this information. The preference store is not possible because the preference store requires a host name that must be available globally.

Is it possible to implement global variables?

Thanks!

Answer 1

There are several options.

A quick and dirty approach is to put the getter for your global variable in the activator of one of your plugins. Then you just get your global view:

SomePluginActivator.getDefault().getGlobalData()

RCP, IEclipsePreferences? :

IEclipsePreferences rootNode = Platform.getPreferencesService().getRootNode();
rootNode.put("currentFileName", "my.file.name.txt");

- :

IEclipsePreferences rootNode = Platform.getPreferencesService().getRootNode();
String currentFileName = rootNode.get("currentFileName", null);
