A radio state that can be read from the registry. This stores a piece of
boolean state information that is grouped with other boolean state to form a
radio group. In a single radio group, there can be at most one state who
value is
Boolean.TRUE all the others must be
Boolean.FALSE .
When parsing from the registry, this state understands three parameters:
default, which is the default value for this item;
persisted, which is whether the state should be persisted
between sessions; id, which is the identifier of the group to
which this radio handler belongs. The default parameter
defaults to false, and the persisted parameter
defaults to true. If only one parameter is passed (i.e.,
using the class name followed by a colon), then it is assumed to be the
id parameter. The id is required for this class
to function properly.
Clients may instantiate this class, but must not extend.
