Interface ClassFilter

All Known Implementing Classes:

AnnotationClassFilter, AspectJExpressionPointcut, ControlFlowPointcut, DefaultIntroductionAdvisor, RootClassFilter, TypePatternClassFilter

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 ClassFilter

Filter that restricts matching of a pointcut or introduction to a given set of target classes.

Can be used as part of a Pointcut or for the entire targeting of an IntroductionAdvisor.

Concrete implementations of this interface typically should provide proper implementations of Object.equals(Object) and Object.hashCode() in order to allow the filter to be used in caching scenarios — for example, in proxies generated by CGLIB.
