org.springframework.context.annotation.FeatureAnnotationParser |
Interface for parsing AnnotationMetadata
from a FeatureAnnotation
into a FeatureSpecification
object. Used in conjunction with a
FeatureSpecificationExecutor
to provide a source-agnostic approach to
handling configuration metadata.
For example, Spring's component-scanning can be configured via XML using
the context:component-scan
element or via the ComponentScan
annotation. In either case, the metadata is the same -- only the source
format differs. ComponentScanBeanDefinitionParser
is used to create
a specification from the <context:component-scan>
XML element, while
ComponentScanAnnotationParser creates a specification from the
the annotation style. They both produce a ComponentScanSpec
object that is ultimately delegated to a ComponentScanExecutor
which understands how to configure a ClassPathBeanDefinitionScanner
,
perform actual scanning, and register actual bean definitions against the
container.
Implementations must be instantiable via a no-arg constructor. TODO SPR-7420: documentation (clean up) TODO SPR-7420: rework so annotations declare their creator.
