A - Annotation containing AdviceMode
attributepublic abstract class AdviceModeImportSelector<A extends Annotation>
Convenient base class for ImportSelector implementations that select imports
based on an AdviceMode value from an annotation (such as the @Enable*
annotations).

protected String getAdviceModeAttributeName()
AdviceMode attribute for the annotation specified by the
generic type A. The default is "mode",
but subclasses may override in order to customize.
public final String[] selectImports(AnnotationMetadata importingClassMetadata)
AnnotationMetadata of the importing @Configuration class.
This implementation resolves the type of annotation from generic metadata and
validates that (a) the annotation is in fact present on the importing
@Configuration class and (b) that the given annotation has an
advice mode attribute of type
AdviceMode.
The selectImports(AdviceMode) method is then invoked, allowing the
concrete implementation to choose imports in a safe and convenient fashion.
selectImports in interface ImportSelectorIllegalArgumentException - if expected annotation A is not present
on the importing @Configuration class or if selectImports(AdviceMode)
returns nullprotected abstract String[] selectImports(AdviceMode adviceMode)
AdviceMode.
Returning null from this method indicates that the AdviceMode could
not be handled or was unknown and that an IllegalArgumentException should
be thrown.
adviceMode - the value of the advice mode attribute for the annotation specified via generics.
null if
the given AdviceMode is unknown.
