Re: [ease-dev] LinkProject very slow with many projects

[Raphael Geissler <raphael.geissler@xxxxxxxxx>]

Hi all,

I have noticed that if I do the same action from an EASE module
wrapping the code in ICoreRunnable
like this:
// Code of an ease module method
  public String linkBundles() {
    try {
      ResourcesPlugin.getWorkspace().run(
        monitor -> projects().stream().forEach(this::linkProject),
        new NullProgressMonitor());
    } catch (CoreException e) {
      return e.getMessage();
    }

    return "";
  }

the action is also fast with many projects. But scripting makes no
sense, if I have to wrap many calls in modules. Is there any way to
have a Function as parameter in a module method, like this:

public void runInWorkspace(Function<Void, Void> f) {
    try {
      ResourcesPlugin.getWorkspace().run(
        monitor -> f.apply(null),
        new NullProgressMonitor());
    } catch (CoreException e) {
    }
  }

Or does someone have a better idea to solve this problem?

BR,

Raphael
