## org.springframework.core.type.filter
Class AnnotationTypeFilter

    java.lang.Object
      org.springframework.core.type.filter.AbstractTypeHierarchyTraversingFilter
          org.springframework.core.type.filter.AnnotationTypeFilter

All Implemented Interfaces:
  TypeFilter

    public class AnnotationTypeFilter

extends AbstractTypeHierarchyTraversingFilter

A simple filter which matches classes with a given annotation, checking inherited annotations as well.

The matching logic mirrors that of `Class.isAnnotationPresent()`.

Since:
  2.5

  Mark Fisher, Ramnivas Laddad, Juergen Hoeller

Constructor Summary
`AnnotationTypeFilter(Class<? extends Annotation> annotationType)` Create a new AnnotationTypeFilter for the given annotation type.
`AnnotationTypeFilter(Class<? extends Annotation> annotationType, boolean considerMetaAnnotations)` Create a new AnnotationTypeFilter for the given annotation type.
`AnnotationTypeFilter(Class<? extends Annotation> annotationType, boolean considerMetaAnnotations, boolean considerInterfaces)` Create a new `AnnotationTypeFilter` for the given annotation type.

Method Summary
`protected boolean` | `matchSelf(MetadataReader metadataReader)` Override this to match self characteristics alone.
`protected Boolean` | `matchSuperClass(String superClassName)` Override this to match on super type name.

Constructor Detail

### AnnotationTypeFilter

    public AnnotationTypeFilter(Class<? extends Annotation> annotationType)

  Create a new AnnotationTypeFilter for the given annotation type. This filter will also match meta-annotations. To disable the meta-annotation matching, use the constructor that accepts a '`considerMetaAnnotations`' argument. The filter will not match interfaces.

  Parameters:
    `annotationType` - the annotation type to match

### AnnotationTypeFilter

    public AnnotationTypeFilter(Class<? extends Annotation> annotationType,
                                boolean considerMetaAnnotations)

  Create a new AnnotationTypeFilter for the given annotation type. The filter will not match interfaces.

  Parameters:
    `annotationType` - the annotation type to match
    `considerMetaAnnotations` - whether to also match on meta-annotations

### AnnotationTypeFilter

    public AnnotationTypeFilter(Class<? extends Annotation> annotationType,
                                boolean considerMetaAnnotations,
                                boolean considerInterfaces)

  Create a new `AnnotationTypeFilter` for the given annotation type.

  Parameters:
    `annotationType` - the annotation type to match
    `considerMetaAnnotations` - whether to also match on meta-annotations
    `considerInterfaces` - whether to also match interfaces

Method Detail

### matchSelf

    protected boolean matchSelf(MetadataReader metadataReader)

  Description copied from class: `AbstractTypeHierarchyTraversingFilter`
  Override this to match self characteristics alone. Typically, the implementation will use a visitor to extract information to perform matching.

  Overrides:
    `matchSelf` in class `AbstractTypeHierarchyTraversingFilter`

### matchSuperClass

    protected Boolean matchSuperClass(String superClassName)

  Description copied from class: `AbstractTypeHierarchyTraversingFilter`
  Override this to match on super type name.

  Overrides:
    `matchSuperClass` in class `AbstractTypeHierarchyTraversingFilter`
