getInstance

public java.util.Set<T> getInstance(InstantiationContext<T> context)
                             throws CreationException

Description copied from interface: InjectionTargetExtension

Creates an instance of type T using the given InstantiationContext. Returning null is allowed to indicate the absence of a value. Depending on the destination where the value is used this can mean null is injected (methods and constructors), that the value is not injected (fields) or that an UnsatisfiedResolutionException is thrown (direct instance resolver call).

Specified by:

Parameters:

context - an InstantiationContext, cannot be null

an instance of type T, can be null
