ValuesManager with Tabs in different classes.

I have logic in different classes (e.g. Tab1.java, Tab2.java) for each tab. ValuesManager is an instance call, but I would prefer not to send the reference to each tab from the entry point.

I'd prefer that
public Tab1 extends Tab {

Tab1 (ValuesManager vm) {
}
}

Are Values Manager services truly an instance local to the java class or is the ValuesManager an API to access services (like RPCManager services)?
