isUnsatisfied

public boolean isUnsatisfied()

Specified by:

isUnsatisfied in interface javax.enterprise.inject.Instance<T>

isAmbiguous

public boolean isAmbiguous()

Specified by:

isAmbiguous in interface javax.enterprise.inject.Instance<T>

destroy

public void destroy(T instance)

Specified by:

destroy in interface javax.enterprise.inject.Instance<T>

getHandler

public WeldInstance.Handler<T> getHandler()

Description copied from interface: WeldInstance

Obtains a contextual reference handler for the bean that has the required type and required qualifiers and is eligible for injection.

Note that each invocation of this method results in a separate Provider.get() invocation.

Specified by:

getHandler in interface WeldInstance<T>

Returns:

a new handler

handlers

public Iterable<WeldInstance.Handler<T>> handlers()

Description copied from interface: WeldInstance

Allows to iterate over contextual reference handlers for all the beans that have the required type and required qualifiers and are eligible for injection.

Note that the returned Iterable is stateless and so each Iterable.iterator() produces a new set of handlers.

Specified by:

handlers in interface WeldInstance<T>

Returns:

an iterable to iterate over the handlers
