Method Detail
-
delegate
public abstract WeldInstance<T> delegate()
-
get
public T get()
Description copied from interface:Provider
Provides a fully-constructed and injected instance ofT
.
-
select
public WeldInstance<T> select(Annotation... qualifiers)
Description copied from interface:Instance
Obtains a child
Instance
for the given additional required qualifiers.
-
select
public <U extends T> WeldInstance<U> select(Class<U> subtype, Annotation... qualifiers)
Description copied from interface:Instance
Obtains a child
Instance
for the given required type and additional required qualifiers.
-
select
public <U extends T> WeldInstance<U> select(TypeLiteral<U> subtype, Annotation... qualifiers)
Description copied from interface:Instance
Obtains a child
Instance
for the given required type and additional required qualifiers.- Specified by:
select
in interfaceInstance<T>
- Specified by:
select
in interfaceWeldInstance<T>
- Type Parameters:
U
- the required type- Parameters:
subtype
- aTypeLiteral
representing the required typequalifiers
- the additional required qualifiers- Returns:
- the child
Instance
-
isUnsatisfied
public boolean isUnsatisfied()
Description copied from interface:Instance
Determines if there is no bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent
Instance
was injected.- Specified by:
isUnsatisfied
in interfaceInstance<T>
- Returns:
true
if there is no bean that matches the required type and qualifiers and is eligible for injection into the class into which the parentInstance
was injected, orfalse
otherwise.
-
isAmbiguous
public boolean isAmbiguous()
Description copied from interface:Instance
Determines if there is more than one bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent
Instance
was injected.- Specified by:
isAmbiguous
in interfaceInstance<T>
- Returns:
true
if there is more than one bean that matches the required type and qualifiers and is eligible for injection into the class into which the parentInstance
was injected, orfalse
otherwise.
-
destroy
public void destroy(T instance)
Description copied from interface:Instance
When called, the container destroys the instance if the active context object for the scope type of the bean supports destroying bean instances. All normal scoped built-in contexts support destroying bean instances.
The instance passed should either be a dependent scoped bean instance obtained from the same
Instance
object, or the client proxy for a normal scoped bean instance.
-
getHandler
public WeldInstance.Handler<T> getHandler()
Description copied from interface:WeldInstance
Obtains an initialized contextual reference handler for the bean that has the required type and required qualifiers and is eligible for injection.The contextual reference is obtained lazily, i.e. when first needed.
- Specified by:
getHandler
in interfaceWeldInstance<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 eachIterable.iterator()
produces a new set of handlers.- Specified by:
handlers
in interfaceWeldInstance<T>
- Returns:
- a new iterable
-
getPriorityComparator
public Comparator<WeldInstance.Handler<?>> getPriorityComparator()
Description copied from interface:WeldInstance
The returned comparator sorts handlers by priority in descending order.- A class-based bean whose annotated type has
jakarta.annotation.Priority
has the priority of valuejakarta.annotation.Priority#value()
- A custom bean which implements
Prioritized
has the priority of valuePrioritized.getPriority()
- Any other bean has the priority of value 0
- Specified by:
getPriorityComparator
in interfaceWeldInstance<T>
- Returns:
- a comparator instance
- A class-based bean whose annotated type has
