produce
Causes an instance to be produced via the
Producer
.If the

if it exists, or the constructor with no parameters otherwise. If the class has interceptors, produce() is responsible for building the interceptors and decorators of the instance.If the
Producer
represents a producer field or method, this will invoke the producer method on, or access the producer field of, a contextual instance of the bean that declares the producer.- Parameters:
ctx
- TheCreationalContext
to use for the produced object- Returns:
- the instance produced
-
dispose

Producer
represents a producer field or method, this calls the disposer method, if any, on a contextual instance of the bean that declares the disposer method or performs any additional required cleanup, if any, to destroy state associated with a resource.- Parameters:
instance
- The instance to dispose
-
getInjectionPoints
Set<InjectionPoint> getInjectionPoints()Returns the set of all
InjectionPoints
. If theProducer
represents a class, then this returns returns the set ofInjectionPoint
objects representing all injected fields, bean constructor parameters and initializer method parameters. For a producer method, this returns the set ofInjectionPoint
