- org.springframework.context.annotation.AdviceModeImportSelector<A>

Type Parameters:
A - annotation containing AdviceMode attribute
All Implemented Interfaces:
ImportSelector
Direct Known Subclasses:
AsyncConfigurationSelector, CachingConfigurationSelector, TransactionManagementConfigurationSelector
```
public abstract class AdviceModeImportSelector<A extends Annotation>
extends Object
implements ImportSelector
```
Convenient base class for ImportSelector implementations that select imports based on an AdviceMode value from an annotation (such as the @Enable* annotations).

Modifier and Type	Method	Description
`protected String`	`getAdviceModeAttributeName()`	The name of the `AdviceMode` attribute for the annotation specified by the generic type `A`.
`protected abstract String[]`	`selectImports(AdviceMode adviceMode)`	Determine which classes should be imported based on the given `AdviceMode`.
`String[]`	`selectImports(AnnotationMetadata importingClassMetadata)`	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`.

- Method Detail
  - getAdviceModeAttributeName
```
protected String getAdviceModeAttributeName()
```
    The name of the AdviceMode attribute for the annotation specified by the generic type A. The default is "mode", but subclasses may override in order to customize.
  - selectImports
```
public final String[] selectImports(AnnotationMetadata importingClassMetadata)
```
    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.
    Specified by:
    selectImports in interface ImportSelector
    Returns:
    the class names, or an empty array if none
    Throws:
    IllegalArgumentException - if expected annotation A is not present on the importing @Configuration class or if selectImports(AdviceMode) returns null
  - selectImports
```
@Nullable
protected abstract String[] selectImports(AdviceMode adviceMode)
```
    Determine which classes should be imported based on the given AdviceMode.
    Returning null from this method indicates that the AdviceMode could not be handled or was unknown and that an IllegalArgumentException should be thrown.
    Parameters:
    adviceMode - the value of the advice mode attribute for the annotation specified via generics.
    Returns:
    array containing classes to import (empty array if none; null if the given AdviceMode is unknown)
