public final class BooleanHolder extends Object implements Streamable
boolean that is mapped into
java boolean.
The holders have several application areas. The end user usually
sees them implementing CORBA methods where the primitive type
is passed by reference. While CORBA (or, for example, C) supports
this, the java does not and a wrapper class is required.
