BeanMap
+ +
BeanMap's entrySet() now properly returns a set containing Map.Entry +objects. Previously, entrySet() was equivalent to keySet() (returns a set of +the readable properties) and there was no mechanism to retrieve all of the +readable properties along with their values. Additionally, the BeanMap clone +method has been revamped to work better for subclasses.
+ +
BeanMap 2.0 compatibility changes:
+
+ +
BeanMap's clone() method now declares it throws + CloneNotSupportedException. This allows subclasses of BeanMap to not require + being Cloneable and facilitates subclasses that wish to be cloneable (allows + the subclass to call super.clone() and have it return an instance of the + child rather than the parent).
+ +
If a BeanMap is not cloneable because a new instance of the underlying + bean cannot be constructed, a CloneNotSupportedException is thrown rather + than an UnsupportedOperationException or other RuntimeException.
+ +
BeanMap's entrySet() method now returns a set of Map.Entry objects rather + than the set of readable properties. To retrieve a set of readable + properties, use keySet() instead.
+ +
+ +
Bugs fixed:
+
+ +
If no bean is set in the BeanMap, or setBean(Object) was called with a + null argument, many BeanMap methods threw NullPointerExceptions. These have + been fixed to properly handle the case where there is no bean established in + the map.
