Typical Use Cases for ServiceReference.getCallback()?
Hello,
I could not find any description on how this method -- getCallback() of a
ServiceReference -- should be used in the Java Annotations & APIs
specification. May I know what would be the typical use cases for it? I
understand RequestContext.getCallback() (and
ServiceReference.setCallback(Obj)) but I'm having a hard time getting
around ServiceReference.getCallback(). Any help is much appreciated.
Thank you!

Thank you, Simon. Guess I attempted to read too much into the
specification. Again, thanks!

This method is the "getter" that matches the setCallback(Obj) method
of ServiceReference. It retrieves the value that was previously set
using setCallback(Obj). This follows the Java convention that
setter methods usually have a corresponding getter.
