Description copied from interface: IOperatorValidator

This method is called in order to validate a given IWorkPackage for an operator.

Within this method execution rules are declared and evaluated.

One may bypass the validation returning true on every call. Note That the execution of the operator is not guaranteed to be finished without uncaught errors!

Specified by:

validate in interface IOperatorValidator

Parameters:

wp - the work package

Returns:

true, if the package is valid for this operator

Throws:

IllegalArgumentException - if the source or parameters do evaluate the rules to true

Exception - if other errors occur during validation

validateSources

protected boolean validateSources(IWorkPackage wp)
                           throws IllegalArgumentException

This method - as default - checks for a source object at index position 0.

Parameters:

wp -

Returns:

true if the source vector contains an IqmDataBox object containing a plot at index 0

Throws:

IllegalArgumentException - if the source vector

• is empty,
• does not contain an IqmDataBox as wrapper, or
• the data box is not of type OperatorType.PLOT.
