+--quoggles.deprecated.stdboxes.unpack.Unpack_Box
Input: an object
Output: null if the input has been null.
If the input is a collection of exactly one element, this element
is returned
All other types of input (empty collections, collections with several elements, objects that are not collections, etc.) produce an error.

public void execute()
throws QueryExecutionException
BoxInputNotSetException if the inputSet
flag indicates the no input has been set for this box.
May throw other QueryExecutionExceptions.
The implementation of this abstract sets the output to be equal to the
input.

throws InvalidInputException

done and some flags are correctly set.

BoxDefaultBoxRepresentation.
If your subclass has any parameters, you will probably have to design
your own representation and override this method for example as follows:
if (iBoxGRep == null || !(iBoxGRep instanceof MYOWNBOX_Rep)) {
iBoxGRep = new MYOWNBOX_Rep(this);
}
return iBoxGRep;
