+--quoggles.auxboxes.getproperty.GetProperty_Box
Input: graph element(s)
Output: a property or a list of properties (the type of property is specified via a parameter) like degree
null values are not put into the output list.
If the resulting list contains only one element, this element is returned (not a one-element list).

public int[] getInputTypes()
BoxgetNumberOfInputs.
getInputTypes in interface IBoxgetInputTypes in class BoxIBox.getInputTypes()public int[] getOutputTypes()
BoxgetNumberOfOutputs.
This implementation returns the same as a call to
getInputTypes yields.
getOutputTypes in interface IBoxgetOutputTypes in class BoxIBox.getOutputTypes()
public void setInputs(java.lang.Object[] inputs)
throws InvalidInputException
Boxsuper.setInputs(inputs)) so that consistency checks are
done and some flags are correctly set.
setInputs in interface IBoxsetInputs in class BoxInvalidInputExceptionIBox.setInputs(java.lang.Object[])public IBoxRepresentation getGraphicalRepresentation()
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;

throws InvalidParameterException
ge -
InvalidParameterException
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.
