[news.eclipse.platform] Re: Workspace save participation

["Lars Vogel" <Lars.Vogel@xxxxxxxxx>]

Hi Rahul,

thank you. I didn't know what the implementation for saving matters expect 
that I read that the method should never thrown an exception. In 
implementing the method I followed closely the example (please see below for 
the code). The method is never called.

The called method plugin.writeImportantState(f); in the class Activator 
currently only contains: System.out.println("Writing");

My assumption is that my Activtator Plugin needs to tell the workbench that 
is has changed / information to save.

Best regards, Lars

public void saving(ISaveContext context) throws CoreException {

System.out.println("I'm not called");

switch (context.getKind()) {

case ISaveContext.FULL_SAVE:

// save the plug-in state

int saveNumber = context.getSaveNumber();

String saveFileName = "save-" + Integer.toString(saveNumber);

File f = plugin.getStateLocation().append(saveFileName).toFile();

// if we fail to write, an exception is thrown and we do not update

// the path

plugin.writeImportantState(f);

context.map(new Path("save"), new Path(saveFileName));

context.needSaveNumber();

break;

case ISaveContext.PROJECT_SAVE:

// get the project related to this save operation

IProject project = context.getProject();

// save its information, if necessary

break;

case ISaveContext.SNAPSHOT:

// This operation needs to be really fast because

// snapshots can be requested frequently by the

// workspace.

break;

}


}
