is of class MyClass employee.(abstract)=true // this bean can't be instantiated directly employee.group=Insurance // real property employee.usesDialUp=false // real property (potentially overridden) salesrep.(parent)=employee // derives from "employee" bean definition salesrep.(lazy-init)=true // lazily initialize this singleton bean salesrep.manager(ref)=tony // reference to another bean salesrep.department=Sales // real property techie.(parent)=employee // derives from "employee" bean definition techie.(singleton)=false // bean is a prototype (not a shared instance) techie.manager(ref)=jeff // reference to another bean techie.department=Engineering // real property techie.usesDialUp=true // real property (overriding parent value) ceo.$0(ref)=secretary // inject 'secretary' bean as 0th constructor arg ceo.$1=1000000 // inject value '1000000' at 1st constructor arg Note: As of Spring 1.2.6, the use of class and parent has been deprecated in favor of (class) and (parent), for consistency with all other special properties. Users should note that support for class and parent as special properties rather then actual bean properties will be removed in a future version.
