Method Detail

dispose back to summary

dispose	back to summary
public void dispose(T instance) Destroys the instance. If the `Producer` represents a class, then this operation does nothing. If the `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:T The instance to dispose

public void dispose(T instance)

Destroys the instance.

If the Producer represents a class, then this operation does nothing.

If the 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:T: The instance to dispose

getInjectionPoints back to summary

getInjectionPoints	back to summary
public Set<InjectionPoint> getInjectionPoints() Returns the set of all `InjectionPoints`. If the `Producer` represents a class, then this returns returns the set of `InjectionPoint` objects representing all injected fields, bean constructor parameters and initializer method parameters. For a producer method, this returns the set of `InjectionPoint` objects representing all parameters of the producer method. Returns:Set<InjectionPoint> the set of all injection points for the producer

public Set<InjectionPoint> getInjectionPoints()

Returns the set of all InjectionPoints. If the Producer represents a class, then this returns returns the set of InjectionPoint objects representing all injected fields, bean constructor parameters and initializer method parameters. For a producer method, this returns the set of InjectionPoint objects representing all parameters of the producer method.

Returns:Set<InjectionPoint>: the set of all injection points for the producer

produce back to summary

produce	back to summary
public T produce(CreationalContext<T> ctx) Causes an instance to be produced via the `Producer`. If the `Producer` represents a class, this will invoke the constructor annotated `javax.inject.Inject` 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:CreationalContext<T> The `javax.enterprise.context.spi.CreationalContext` to use for the produced object Returns:T the instance produced

public T produce(CreationalContext<T> ctx)

Causes an instance to be produced via the Producer.

If the Producer represents a class, this will invoke the constructor annotated javax.inject.Inject 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:CreationalContext<T>: The javax.enterprise.context.spi.CreationalContext to use for the produced object

Returns:T

the instance produced

public Interface Producer<T>
