Detailed Description

This interface defines information that can be returned for a given property. It is similar to the java.beans. PropertyDescriptor but it aims to be a complementary and ligther version of it.

The properties of a JavaBean are describe using the PropertyDescriptor returned by the BeanInfo. If you provide an explicit BeanInfo you can use the PropertyDescriptor to specify the needed information (expert, hidden, PropertyEditor ...) and you do not need to use this interface.

If you do not provide an explicit BeanInfo you cannot specify that information as the PropertyDescriptor will be automatically generated by the Introspector. In this case, you can returned an array of PropertyInfo specifying the proper information directly from your bean. The node representing the bean will invoke the method to get that array of PropertyInfo and use the information from it.
