package provided.listFW.visitors

A package of provided visitors (algorithms) for use with the listFW visitor system and accumulators for use with the FoldLAlgo and FoldRAlgo visitors.

Interface Summary

Interface	Description
IAccumulator	An accumulator for use in FoldR and FoldL.

Class Summary

Class	Description
AAccumulator	An IAccumulator that holds an Object as its internal value and who's string representation is the string representation of that value.
AddToAlgo	Returns a copy of the list where the single integer parameter is added to all elements
CopyAcc	Accumulates the values into a list, starting with an empty list.
CopyAlgo	Returns a copy of the list
CountAlgo	Returns the count of the number of elements in the list
FoldLAlgo	Performs the fold-left (forward accumulation) algorithm using the given IAccumulator The general forward accumulation algorithm would not take an accumulator as a top-level input parameter, instead the accumulator would be hidden inside the algorithm.
FoldRAlgo	Performs the fold-right (reverse accumulation) algorithm using the given IAccumulator.
LastNegAcc	Accumulates (saves) the last negative number given to it.
ProdAcc	Accumulates the product of the values, starting with a total of 1.
ProdAlgo	Algo to calculate the product of all the elements in a list of integers.
SumAcc	Accumulates the sum of the values, starting with a total of 1.
SumFwdAlgo	Returns the sum of a list of integers using forward accumulation.
SumRevAlgo	Returns the sum of a list of integers using reverse accumulation.
ToStringAlgo	Computes a String representation of IList showing a left parenthesis followed by elements of the IList separated by commas, ending with with a right parenthesis.
ToStringHelper	Helps ToStringAlgo compute the String representation of the rest of the list.
