| Method Summary |
|
| public synchronized void | addView(Polymorphic other)
add another view for this object. |
| protected boolean | already(Class t)
Answer true iff this is already acceptable to the given type t. |
| protected boolean | alreadyHasView(Class t)
Answer true iff this polymorphic object already has a valid view of
type t in its ring (so .as()ing it doesn't need to
construct a new object). |
| final protected Polymorphic | asInternal(Class t)
Answer a polymorphic object that presents this in a way which satisfies type
t. |
| abstract protected boolean | canSupport(Class t)
subclasses must provide a method for testing if _this_ can be
converted to an instance of _t_. |
| abstract protected Polymorphic | convertTo(Class t)
subclasses must provide a method for converting _this_, if
possible, into an instance of _t_. |
| abstract public boolean | equals(Object o)
subclasses must override equals. |
| abstract protected Personality | getPersonality()
|
| abstract public boolean | isValid()
answer true iff this enhanced node is still underpinned in the graph
by triples appropriate to its type. |
| public boolean | supports(Class t)
return _true_ iff this polymorphic object supports the specified interface.
Synonymous with "does the argument class have this as an instance".
Actually it shouldn't be. |
