public class GenericData extends AbstractMap<String,Object> implements Cloneable
Subclasses can declare fields for known data keys using the Key
annotation. Each field
can be of any visibility (private, package private, protected, or public) and must not be static.
null
unknown data key names are not allowed, but null
data values are allowed.
Iteration order of the data keys is based on the sorted (ascending) key names of the declared fields, followed by the iteration order of all of the unknown data key name/value pairs.
Implementation is not thread-safe. For a thread-safe choice instead use an implementation of
ConcurrentMap
.

) for the given field name. Any existing value
for the field will be overwritten. It may be more slightly more efficient than put(String, Object)
because it avoids accessing the field's original value.
Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.
