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.

WARNING: Concrete implementations of this interface must provide proper implementations of Object.equals(Object), Object.hashCode(), and Object.toString() in order to allow the filter to be used in caching scenarios — for example, in proxies generated by CGLIB. As of Spring Framework 6.0.13, the toString() implementation must generate a unique string representation that aligns with the logic used to implement equals(). See concrete implementations of this interface within the framework for examples.
