Interface AutoBean<T>
- Type Parameters:
T
- the type of interface that will be wrapped.
public interface AutoBean<T>
A controller for an implementation of a bean interface. Instances of
AutoBeans are obtained from an
AutoBeanFactory

Method Details
-
as
T as()Returns a proxy implementation of theT
interface which will delegate to the underlying wrapped object, if any.- Returns:
- a proxy that delegates to the wrapped object
-
clone
Deprecated.with no replacementThis method always throws anUnsupportedOperationException
. The implementation of this method in previous releases was not sufficiently robust and there are no further uses of this method within the GWT code base. Furthermore, there are many different semantics that can be applied to a cloning process that cannot be adequately addressed with a single implementation.A simple clone of an acyclic datastructure can be created by using
AutoBeanCodex
to encode and decode the root object. Other cloning algorithms are best implemented by using anAutoBeanVisitor
.- Throws:
UnsupportedOperationException
-
getFactory
AutoBeanFactory getFactory()Returns the AutoBeanFactory that created the AutoBean.- Returns:
- an AutoBeanFactory
-
getTag
Retrieve a tag value that was previously provided tosetTag(String, Object)
.- Parameters:
tagName
- the tag name- Returns:
- the tag value
- See Also:
-
getType
Returns the wrapped interface type. -
isFrozen
boolean isFrozen()Returns the value most recently passed tosetFrozen(boolean)
, orfalse
if it has never been called.- Returns:
true
if this instance is frozen
-
isWrapper
boolean isWrapper()Returnstrue
if the AutoBean was provided with an external object.- Returns:
true
if this instance is a wrapper
-
setFrozen
void setFrozen(boolean frozen) Disallows any method calls other than getters. All setter and call operations will throw anIllegalStateException
.- Parameters:
frozen
- iftrue
, freeze this instance
-
setTag
A tag is an arbitrary piece of external metadata to be associated with the wrapped value.- Parameters:
tagName
- the tag namevalue
- the wrapped value- See Also:
-
unwrap
T unwrap()If the AutoBean wraps an object, return the underlying object. The AutoBean will no longer function once unwrapped.- Returns:
- the previously-wrapped object
- Throws:
IllegalStateException
- if the AutoBean is not a wrapper
