- Type Parameters:
T - the type of the object being held
- All Known Implementing Classes:
- SimpleHolder
public interface Holder<T>
A holder containing an object reference. Its main purpose is to allow you to
create a serializable proxy around an object of a concrete class (usually a
test case class), so that a Wicket page can access the fields in that object
through this path: page => serializable holder proxy => object => fields.
If you don't use a holder, the access path will be: page => serializable
object proxy => object, but using this path only method calls will pass
through, but field accesses will hit those in the proxy itself.
