Method Detail

getStartResult

public Value getStartResult(IDatatype type,
                            IDatatype iterType)
                     throws ValueDoesNotMatchTypeException

Description copied from interface: IIteratorEvaluator

Returns the start result. Used in case of all operations where the start result is implicitly clear from the operation itself and not explicitly defined in the model.

Specified by:

getStartResult in interface IIteratorEvaluator

Parameters:

type - the type of the return value

iterType - the type of the iterator expression

Returns:

the start value (must comply to type)

Throws:

ValueDoesNotMatchTypeException - in case of type compatibility problems

postProcessResult

public void postProcessResult(EvaluationAccessor result,
                              java.util.Map<java.lang.Object,java.lang.Object> data)
                       throws ValueDoesNotMatchTypeException

Description copied from interface: IIteratorEvaluator

Called to post-process the actual result at the end after the last iteration.

Specified by:

postProcessResult in interface IIteratorEvaluator

Parameters:

result - the aggregated result so far

data - arbitrary data to be hold while actually evaluating the function

Throws:

ValueDoesNotMatchTypeException - in case of type compatibility problems
