Method Detail

getBeanClass

public java.lang.Class getBeanClass()

Description copied from interface: Bean

Returns the bean class.

Specified by:

getBeanClass in interface Bean<T>

create

public T create(CreationalContext<T> env)

Description copied from interface: Contextual

create in interface Contextual<T>

Parameters:

env - the creation context used to support circular references.

Returns:

the new instance

destroy

public void destroy(T instance,
                    CreationalContext<T> env)

Description copied from interface: Contextual

Destroys an instance for the Contextual's type.

1. Call any @Disposal method
2. Call @PreDestroy methods
3. Destroy dependent objects

Specified by:

destroy in interface Contextual<T>

Parameters:

instance - the instance to destroy
