Package io.micronaut.core.beans
Interface BeanIntrospectionReference<T>
- Type Parameters:
T
- The bean type
- All Superinterfaces:
AnnotationMetadataProvider
,AnnotationSource
,Named
- All Known Implementing Classes:
AbstractBeanIntrospectionReference
,AbstractEnumBeanIntrospectionAndReference
,AbstractInitializableBeanIntrospectionAndReference
A reference to a
BeanIntrospection
that may or may not be present on the classpath.
This interface allows soft loading a BeanIntrospection
without knowing if the class is present on the classpath or not. It also ensures that less memory is occupied as only a reference to the annotation metadata is retained and the full bean can be loaded via the load()
method.
In general results of the load()
do not need to be cached as object creation is cheap and no runtime analysis is performed so it is extremely fast.
