Class FeatureDescriptor
java.lang.Object | +--java.beans.FeatureDescriptor
- Direct Known Subclasses:
- BeanDescriptor, EventSetDescriptor, MethodDescriptor, ParameterDescriptor, PropertyDescriptor
- public class FeatureDescriptor
- extends Object
The FeatureDescriptor class is the common baseclass for PropertyDescriptor, EventSetDescriptor, and MethodDescriptor, etc.
It supports some common information that can be set and retrieved for any of the introspection descriptors.
In addition it provides an extension mechanism so that arbitrary attribute/value pairs can be associated with a design feature.
