Examples of com.ericsson.ssa.sip.SipSessionDialogImpl$AttributeCallback

com.ericsson.ssa.sip.SipSessionDialogImpl
Helper interface for invocation of a callback on a listener. This interface is used to be able to write the callAttributeListeners method without duplicating that code and hence have a maintenance problem. An alternative to this approach is to use a switch case on an enum or to use reflection. I like this approach best since it is the most object oriented and type safe approach. @author Magnus Hessel, HiQ Stockholm AB
