Parameters:

creationalContext - the contextual instance shall be created in

Returns:

instance of the bean

createDefaultInstance

protected T createDefaultInstance(javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Default producer method creation.

Parameters:

creationalContext - creational context

Returns:

producer method instance

getCreatorField

public Field getCreatorField()

Gets creator field.

Returns:

creator field

getActualTypeArguments

public Type[] getActualTypeArguments()

Returns actual type arguments.

Returns:

actual type arguments

setProducerField

public void setProducerField(Field field)
