/*
Miscellaneous method additions to NSException
the additions make it easier using exceptions in the Java way. In OpenStep
exceptions are identified by their name, subclasses are mainly used when
additional information needs to be stored. This works well as long as you do
not use exceptions very much (as in the Foundation Kit) - if you do you
soon wish to have a 'hierachy' of exceptions. This can be modelled - like in
Java - using a subclass for each different kind of exception and then using
the type of the exception for it's identification. This is supported by
libFoundation using the TRY and CATCH macros.
The methods below always use the class name as the exception name if the name
isn't specified explicitly.

/*
The following macros are for use of locks together with exception handling.
A synchronized block is properly 'unlocked' even if an exception occures.
It is used this way:
SYNCHRONIZED(MyObject) {
THROW(MyException..);
}
END_SYNCHRONIZED;
Where MyObject must be an object that conforms to the NSObject and NSLocking
protocol.
This is much different to
[MyObject lock];
{
THROW(MyException..);
}
[MyObject unlock];
which leaves the lock locked when an exception happens.
