Deleting in EOF

Usually deleting is pretty easy:

Person person; //Assume is an EO that exists
EOEditingContext ec = person.editingContext(); //Always make sure you are using the correct editing context
ec.deleteObject(person); //Mark the EO for deletion
ec.saveChanges(); //Commit

A little more robust example:

Person person; /Assume is an EO that exists
EOEditingContext ec = person.editingContext();
ec.deleteObject(person);

try {
  ec.saveChanges();
} catch (Exception e) {
  //something bad happened, the delete didn't occur
  //well don't just stand there, do something about it!
  ec.revert(); // clean up the mess
}

NOTE: These examples assume that correct EOEditingContext locking is occuring, ProjectWonder's ERXEC auto-locking is highly recommended.
