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(Class).

Since:

2.5

Constructor Detail

AnnotationTypeFilter

public AnnotationTypeFilter(java.lang.Class<? extends java.lang.annotation.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(java.lang.Class<? extends java.lang.annotation.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(java.lang.Class<? extends java.lang.annotation.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 java.lang.Boolean matchSuperClass(java.lang.String superClassName)

Description copied from class: AbstractTypeHierarchyTraversingFilter

Override this to match on super type name.

Overrides:

matchSuperClass in class AbstractTypeHierarchyTraversingFilter

matchInterface

protected java.lang.Boolean matchInterface(java.lang.String interfaceName)

Description copied from class: AbstractTypeHierarchyTraversingFilter

Override this to match on interface type name.

Overrides:

matchInterface in class AbstractTypeHierarchyTraversingFilter

hasAnnotation

protected java.lang.Boolean hasAnnotation(java.lang.String typeName)
