Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface AnnotationFilter
```
Callback interface that can be used to filter specific annotation types.
Note that the MergedAnnotations model (which this interface has been designed for) always ignores lang annotations according to the PLAIN filter (for efficiency reasons). Any additional filters and even custom filter implementations apply within this boundary and may only narrow further from here.

Field Summary

Fields
Modifier and Type	Field	Description
`static AnnotationFilter`	`ALL`	`AnnotationFilter` that always matches and can be used when no relevant annotation types are expected to be present at all.
`static AnnotationFilter`	`JAVA`	`AnnotationFilter` that matches annotations in the `java` and `javax` packages and their subpackages.
`static AnnotationFilter`	`NONE`	Deprecated. as of 5.2.6 since the `MergedAnnotations` model always ignores lang annotations according to the `PLAIN` filter (for efficiency reasons)
`static AnnotationFilter`	`PLAIN`	`AnnotationFilter` that matches annotations in the `java.lang` and `org.springframework.lang` packages and their subpackages.

  - PLAIN
```
static final AnnotationFilter PLAIN
```
    AnnotationFilter that matches annotations in the java.lang and org.springframework.lang packages and their subpackages.
    This is the default filter in the MergedAnnotations model.
  - JAVA
```
static final AnnotationFilter JAVA
```
    AnnotationFilter that matches annotations in the java and javax packages and their subpackages.
  - ALL
```
static final AnnotationFilter ALL
```
    AnnotationFilter that always matches and can be used when no relevant annotation types are expected to be present at all.
  - NONE
```
@Deprecated
static final AnnotationFilter NONE
```
    Deprecated.
    as of 5.2.6 since the MergedAnnotations model always ignores lang annotations according to the PLAIN filter (for efficiency reasons)
    AnnotationFilter that never matches and can be used when no filtering is needed (allowing for any annotation types to be present).
