Eclipse: Set "Text file encoding" by code

I wrote an Eclipse Plugin in order to set up a new Java Project that is prepared with files and libraries and other stuff we need every time we create a new project. Now I would like to set "Text file encoding=UTF-8" and "New text file delimiter=Unix" as well.

For "Text file encoding" I did this by:

IProject project = ...
project.setDefaultCharset("UTF-8", null)

And after that in Project->Properties->Resource it is set to UTF-8.

My Question: But I do not find an IProject-Method that allows me to do the same for "text file delimiter". Is it possible to do this by org.eclipse.core as well?

Solution

This is just set in a preferences value.

The code for this is in org.eclipse.ui.internal.ide.LineDelimiterEditor which uses:

String val = ... line separator ...

Preferences node = Platform.getPreferencesService().getRootNode().node(ProjectScope.SCOPE)
      .node(project.getName()).node(Platform.PI_RUNTIME);

node.put(Platform.PREF_LINE_SEPARATOR, val);

node.flush();

Note: since this is in an internal class it is not guaranteed to be the same in all releases.
