public abstract class BeanMap extends Object implements Map
Map
-based view of a JavaBean. The default set of keys is the
union of all property names (getters or setters). An attempt to set
a read-only property will be ignored, and write-only properties will
be returned as null
. Removal of objects is not a
supported (the key set is fixed).Modifier and Type | Class and Description |
