Note these methods will be called asynchronously when notifications of remote
changes are received by the provider implementation code. The provider is
free to call the methods below with an arbitrary thread, so the
implementation of these methods must be appropriately prepared.
For example, if the code implementing any of these methods must interact with
user interface code, then it should use code such as the following to execute
on the SWT UI thread:
Display.getDefault().asyncExec(new Runnable() {
public void run() {
... UI code here
}
});
Further, the code in the implementations of these methods should not block via
I/O operations or blocking UI calls.
