To create a sorted collection in which the elements are sorted in other
than ascending numerical order, you send a sortBlock:
message to
SortedCollection
. The block following the sortBlock:
selector is a two-parameter block that answers true
if and only if
the first element is to appear before the second. Thus, if
[:x :y | x < y]
is the sort block, you might as well create the
sorted collection using new
; if [:x :y | x > y]
is the sort
block, the elements are sorted in descending order.
