Inbox copy() throws FTLException
When a SubscriberListener
callback method gets an inbox
from a field of an inbound message, the message owns that inbox
object. FTL implicitly destroys that embedded inbox object
when the callback returns. Programs can use this call to copy
the inbox object.
Similarly, when a program gets an inbox from a subscriber object, the subscriber owns that inbox. FTL implicitly destroys that embedded inbox object when the program closes the subscriber. Programs can use this call to copy the inbox object.
Programs must explicitly destroy copies (with
destroy
).
FTLException
Message.getInbox
,
Subscriber.getInbox
void destroy() throws FTLException
A program that copies an inbox object must explicitly destroy it to reclaim its resources.
Note: Message.setInbox
copies its inbox argument into a message field. After
the call returns, a program may destroy the source inbox
without affecting the message.
