setInputs(java.lang.Object[] inputs)
Checks if the number of inputs is correct and sets the inputs. |

setParameters(org.graffiti.plugin.parameter.Parameter[] pars,
boolean fromRep)
Sets the parameters and - if needed - sets them in the graphical representation. |

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.
execute in interface IBoxexecute in class BoxQueryExecutionExceptionIBox.execute()
public void setInputs(java.lang.Object[] inputs)
throws InvalidInputException
Boxsuper.setInputs(inputs)) so that consistency checks are
done and some flags are correctly set.

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;
