IndexedPropertyDescriptor

AI-generated Key Takeaways

• IndexedPropertyDescriptor extends PropertyDescriptor and provides information about indexed properties of a Java Bean.

• It includes methods to get and set the indexed read (getter) and write (setter) methods.

• Three constructors are available, allowing creation from property name and bean class, or using explicit getter/setter methods.

• It provides methods to retrieve the indexed property type and to determine equality with other IndexedPropertyDescriptor objects.

• It inherits various methods for property and feature descriptions from its parent classes.
