Interface EscotReferenced

All Known Implementing Classes:

PropertyAdapter

public interface EscotReferenced

Objects implementing this interface have a reference to a property which may be replaced. EscotReferenced can be used when a component wants to refer to a model instead of maintaining its own copy. This is useful when the model is large, like a TableModel, or when the model is of unknown size and complexity, for example when wrapping a JavaBean property of unknown type.
