Use eStorage in EMF

In my EObject I have the field eStorage, which contains data, I want to use.

Is there a possibility to read out the eStorage?

I tried the code below but it doesn't work:

doIt(EObject object) {
    object.getEStorage;
    // use the eStorage...
}

Chances are that eStorage is a private field.

So either,

• Re-read the javadoc of the EObject interface and/or the javadoc of the particular implementation of EObject you're using. You may find a method offering the data you're looking for.
• Access the private field via Reflection

try {
    Field f = object.getClass().getDeclaredField("eStorage"); 
    f.setAccessible(true);
    Object theDataYouWant = f.get(object);
} catch(Exception e) {
    // Handle exception here...
}
