cn.taketoday.core.type.filter.AbstractTypeHierarchyTraversingFilter

cn.taketoday.core.type.filter.AnnotationTypeFilter

所有已实现的接口:

TypeFilter

public class AnnotationTypeFilter
extends AbstractTypeHierarchyTraversingFilter

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

By default, the matching logic mirrors that of AnnotationUtils.getAnnotation(java.lang.reflect.AnnotatedElement, Class), supporting annotations that are present or meta-present for a single level of meta-annotations. The search for meta-annotations my be disabled. Similarly, the search for annotations on interfaces may optionally be enabled. Consult the various constructors in this class for details.

从以下版本开始:

AnnotationTypeFilter

public AnnotationTypeFilter(Class<? extends Annotation> annotationType)

Create a new AnnotationTypeFilter for the given annotation type.

The 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.

参数:

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.

参数:

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.

参数:

annotationType - the annotation type to match

considerMetaAnnotations - whether to also match on meta-annotations

considerInterfaces - whether to also match interfaces

方法详细资料

getAnnotationType

public final Class<? extends Annotation> getAnnotationType()

Return the Annotation that this instance is using to filter candidates.

matchSelf

protected boolean matchSelf(MetadataReader metadataReader)

从类复制的说明: AbstractTypeHierarchyTraversingFilter

Override this to match self characteristics alone. Typically, the implementation will use a visitor to extract information to perform matching.

覆盖:

matchSelf 在类中 AbstractTypeHierarchyTraversingFilter

matchSuperClass

@Nullable
protected Boolean matchSuperClass(String superClassName)

从类复制的说明: AbstractTypeHierarchyTraversingFilter

Override this to match on super type name.

覆盖:

matchSuperClass 在类中 AbstractTypeHierarchyTraversingFilter

matchInterface

@Nullable
protected Boolean matchInterface(String interfaceName)

从类复制的说明: AbstractTypeHierarchyTraversingFilter

Override this to match on interface type name.

覆盖:

matchInterface 在类中 AbstractTypeHierarchyTraversingFilter

hasAnnotation

@Nullable
protected Boolean hasAnnotation(String typeName)
