[cdi-dev] [JBoss JIRA] Commented: (CDI-10) Add ability to access a bean instance from a proxy
[
https://issues.jboss.org/browse/CDI-10?page=com.atlassian.jira.plugin.sys...
]
Stuart Douglas commented on CDI-10:
-----------------------------------
Say we have a bean:
@SessionScoped
class MyBean {
private String field;
}
It may be that a portable extension needs to read the value of field, but atm that is not
possible, as the proxies field will be read instead. I propose that we allow something
like this:
MyBean proxy = injectedProxyInstance;
MyBean underlying = ((BeanProxy)injectedProxyInstance).getUnderlyingBean();
I am not really sure that this is such a good idea any more, but this was the original
intent.
Add ability to access a bean instance from a proxy
--------------------------------------------------
Key: CDI-10
URL: https://issues.jboss.org/browse/CDI-10
Project: CDI Specification Issues
Issue Type: Feature Request
Components: Beans
Affects Versions: 1.0
Reporter: Stuart Douglas
Fix For: TBD
There are occasions when it would be useful to access a bean instance directly from a
proxy. This could be achieved by making all proxies assignable to an interface (say
BeanProxy) that provides a getBeanInstance() method.
Client code that needs access to the actual instance can check if the object is
assignable to the BeanProxy interface and then call getBeanInstance() to get the actual
instance if required.
This is something that is probably more useful to extension writers than the end user,
but there have already been a few requests on the weld forum about this so it is probably
worth considering.
