Field Detail

annotationUtil

private AnnotationUtilImpl annotationUtil

The AnnotationUtilImpl to use.

annotationType

private final Class<? extends Annotation> annotationType

The required annotation.

forceInheritence

private final boolean forceInheritence

If true then also types are accepted if one of their super-types (including implemented interfaces) is properly annotated (see AnnotationUtilImpl.getTypeAnnotation(Class, Class)).

Constructor Detail

AnnotationFilter

public AnnotationFilter(Class<? extends Annotation> annotationType)
                 throws IllegalArgumentException

The constructor.

Parameters:

annotationType - is the annotation that has to be present if a type should be accepted.

Throws:

IllegalArgumentException - if the given annotationType is NO runtime annotation.

AnnotationFilter

public AnnotationFilter(Class<? extends Annotation> annotationType,
                        boolean forceInheritence)
                 throws IllegalArgumentException

The constructor.

Parameters:

annotationType - is the annotation that has to be present if a type should be accepted.

forceInheritence - if true then also types are accepted if one of their super-types (including implemented interfaces) is properly annotated (see AnnotationUtilImpl.getTypeAnnotation(Class, Class)).

Throws:

IllegalArgumentException - if the given annotationType is NO runtime annotation.

AnnotationFilter

public AnnotationFilter(Class<? extends Annotation> annotationType,
                        boolean forceInheritence,
                        AnnotationUtilImpl annotationUtil)
                 throws IllegalArgumentException

The constructor.

Parameters:

annotationType - is the annotation that has to be present if a type should be accepted.

forceInheritence - if true then also types are accepted if one of their super-types (including implemented interfaces) is properly annotated (see AnnotationUtilImpl.getTypeAnnotation(Class, Class)).

annotationUtil - is the AnnotationUtilImpl instance to use.

Throws:

IllegalArgumentException - if the given annotationType is NO runtime annotation.

Method Detail

accept

public boolean accept(Class<?> type)

This method determines if the given value should be accepted.

Specified by:

accept in interface Filter<Class<?>>
