For what it's worth, I've always used ~Support to indicate a class that is
used via delegation to fulfill the contract of an interface.
e.g.
interface XxxInterface
{
public void a();
}
abstract class AbstractXxx
implements XxxInterface
{
public void a() { ...; }
}
class XxxSupport
// may extend AbstractXxx
{
public void a() { ...; }
}
then you can do
class MyClass
extends AbstractXxx
{
...
}
or
class MyClass
implements XxxInterface
{
private XxxSupport support = new XxxSupport();
public void a() { support.a(); }
}
This is in the spirit of java.beans.PropertyChangeSupport.
