oscript.data.Reference
| Reference | | final public class Reference extends Value (Code) | | A reference forwards all method calls to the object it is a reference
for, but additionally a reference is assignable. It is used when a
variable (or array element) is looked up within a scope, and can be
used as either an lval or rval.
When a property of an object (ie a scope) has attributes associated
with it, those attributes are attributes of the reference. The
attributes are partially enforced by this class (in the case of
"const"), and by ScriptObject (in the case of "public").
Note that this could extends
AbstractReference , but doesn't
because I think that would have a performance impact... one of these
days I should actually verify that...

| Reference | | public Reference()(Code) | | Class Constructor. Create a reference with the default attributes.
|
| Reference | | public Reference(int attr)(Code) | | Class Constructor. Create a reference with the specified attributes.
Parameters:
attr - attribute bitmask |
| getAttr | | int getAttr()(Code) | | Get access to this reference's attributes.
|
| getMonitor | | public Object getMonitor()(Code) | | Return the object used for implementing synchronized. For a
normal script object, the object is it's own monitor. For a java
object, it is the java object rather than the
JavaObjectWrapper .
the object to synchronize on |
| getType | | public Value getType()(Code) | | Get the type of this object. A reference doesn't actually have a type,
but instead is the type of whatever it contains... really I am not sure
if a reference is a first class type, or perhaps could be implemented
as an inner-class for OArray and ScriptObject. Perhaps Value should be
an interface, and what is now Value becomes some sort of adapter
class?
the object's type |
| getTypeImpl | | protected Value getTypeImpl()(Code) | | Get the type of this object. The returned type doesn't have to take
into account the possibility of a script type extending a built-in
type, since that is handled by
Reference.getType .
the object's type |
| getTypeMember | | protected Value getTypeMember(Value obj, int id)(Code) | | Get a member of this type. This is used to interface to the java
method of having members be attributes of a type. Regular object-
script object's members are attributes of the object, but in the
case of java types (including built-in types), the members are
attributes of the type.
Parameters:
obj - an object of this type
Parameters:
id - the id of the symbol that maps to the member a reference to the member, or null |
| isA | | public boolean isA(Value type)(Code) | | If this object is a type, determine if an instance of this type is
an instance of the specified type, ie. if this is type,
or a subclass.
Parameters:
type - the type to compare this type to true or false
throws:
PackagedScriptObjectException - (NoSuchMemberException) |
| isPublic | | boolean isPublic()(Code) | | Determine if this reference is public. This is used by ScriptObject to
determine if it should restrict access to this reference.
true if public, else false |
| memberSet | | final public java.util.Set memberSet()(Code) | | Returns the names of the members of this object.
a collection view of the names of the members of this object |
| reset | | final void reset(int attr)(Code) | | Reset this reference, which is used when the reference is re-used (in-
stead of re-allocating)
|
| reset | | final public void reset()(Code) | | |
| unhand | | public Value unhand()(Code) | | For references to an object (ie variables), this returns the actual
value this is a reference to, otherwise this return this.
the actual object |
