Method Summary

java.lang.Object	createAccumulatorValue(DomainEvaluator evaluator, TypeId accumulatorTypeId, TypeId bodyTypeId) Create the value that will accumulate the iteration results.
protected java.lang.Object	resolveTerminalValue(DomainIterationManager iterationManager) Return the final result at the end of an iteration over all the source elements.
protected java.lang.Object	updateAccumulator(DomainIterationManager iterationManager) Update the accumulatorValue with the bodyValue resulting from the current iteration for which the iterators define the context in the environment.

createAccumulatorValue

                                                       DomainEvaluator evaluator,

                                                       TypeId bodyTypeId)

Description copied from interface: LibraryIteration

Create the value that will accumulate the iteration results.

Parameters:

evaluator - that supervises evaluation

Returns:

the accumulator

resolveTerminalValue

@Nullable
protected java.lang.Object resolveTerminalValue(@NonNull
                                                         DomainIterationManager iterationManager)

Description copied from class: AbstractIteration

Return the final result at the end of an iteration over all the source elements. The default implementation just returns the accumulator. Derived iterations should override.
This method is bypassed if the iteration ends prematurely.

Overrides:

resolveTerminalValue in class AbstractIteration

Parameters:

iterationManager - the iteration context

Returns:

the result

updateAccumulator

@Nullable
protected java.lang.Object updateAccumulator(@NonNull
                                                      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-CARRY_ON premature result of iteration, or CARRY_ON if complete
