Answer the receiver’s sort criteria sortBlock: aSortBlock. Change the sort criteria for a sorted collection, resort the elements of the collection, and return it. WebSortedCollection provides that extra capability. By default, elements are sorted in ascending order. You can override this default by specifying an alternative sort algorithm enclosed in a block. For example, The expression: SortedCollection sortBlock: [:x :y x >= y] creates a new collection whose elements will be sorted in descending order.

WebSortedCollection uses quickSort to resort and a binary search when adding/removing elements. Because insertion/removal may require that remaining elements have to be shifted within the container, adding many individual elements may be done faster by creating a completely new collection from the unsorted elements. shut down unexpectedly windows 10http://computer-programming-forum.com/3-smalltalk/6fc1cc8b9e98b5bb.htm shutdown un pc a distance cmdWebSmalltalk.
