Method Detail

chunkifyList

public static <T> List<List<T>> chunkifyList(List<T> list,
                                             int maxChunkSize)

Splits a list into a set of sublists (preserving order) where the size of each sublist is bound by a given max size, and ensuring that no list has fewer than half the max size number of elements. In other words, you won't get a little rinky-dink sublist at the end that only has one or two items from the original list. Based on: http://www.chinhdo.com/20080515/chunking/

Parameters:

list - list to be chunkified

maxChunkSize - how big you want the chunks to be

Returns:

a chunkified list (i.e., list of sublists)
