|
+--quoggles.stdboxes.comparetwovalues.CompareTwoValues_Box
Input: two java objects
Output: true iff the objects are considered to be equal (this
depends on the values of the parameters). Inputs are converted to the type
specified by parameter. EMPTY inputs can only be evaluated
if comparison is string based. An EMPTY value is then
represented via the empty string "".

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.

This implementation returns the same as a call to

public void setInputs(java.lang.Object[] inputs)
throws InvalidInputException
Boxsuper.setInputs(inputs)) so that consistency checks are
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;
