public interface BeanIntrospector
Definition of an interface for components that can perform introspection on bean classes.
Before
PropertyUtils
can be used for interaction with a specific Java class, the class's properties have to be determined. This is called introspection and is initiated automatically on demand.PropertyUtils
does not perform introspection on its own, but delegates this task to one or more objects implementing this interface. This makes it possible to customize introspection which may be useful for certain code bases using non-standard conventions for accessing properties.- Since:
