An annotation used to specify some property-related information for the automatically generated BeanInfo classes. This annotation is not used if the annotated class has a corresponding user-defined BeanInfo class, which does not imply the automatic analysis. If both the read and the write methods of the property are annotated, then the read method annotation will have more priority and replace the write method annotation.
