Description copied from interface: LibraryIteration

Create the value that will accumulate the iteration results.

Parameters:

evaluator - that supervises evaluation

Returns:

the accumulator

updateAccumulator

protected Value updateAccumulator(DomainIterationManager iterationManager)

Description copied from class: AbstractIteration

Update the accumulatorValue with the bodyValue resulting from the current iteration for which the iterators define the context in the environment.

Specified by:

updateAccumulator in class AbstractIteration

Parameters:

iterationManager - the iteration context

Returns:

non-null premature result of iteration, or null if complete
