Smalltalk sortedcollection
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. WebSmalltalk is a purely object oriented programming language (OOP), created in the 1970s for educational use, specifically for constructionist learning, at Xerox PARC by Learning Research Group (LRG) scientists, including Alan …

Webcanceled from SortedCollection. 5.2 Extending the Analysis The process for analyzing class libraries can be applied to other parts of the Smalltalk. One area that would benefit from examination is the stream classes. These classes are conceptually similar to collections, but are implemented in an entirely different part of the class system. http://duoduokou.com/java/69074778470494694928.html
WebThe Smalltalk-like collection classes of Tools.h++ give you much of the functionality of such Smalltalk namesakes as Bag and SortedCollection, along with some of the strengths and weaknesses of C++. The greatest advantages of the Smalltalk-like collections are their simple programming interface, powerful I/O abilities, and high code reuse.
