| |  | |
Dear all,
it may be a friday afternoon issue, but I was looking for a remove
variant which removed elements from a vector, but not throwing them
away in the first place, but keeping a copy so that I still could do
things with the removed elements before actually destroy them.
So in the STL you have the 'remove(_if)' function which removes
elements. However the 'remove_copy' does not remove elements form the
original input! It has more the semantic of a 'copy_if_not' function
(also implicitly pointed out by Austern, by implementing 'copy_if' in
terms of 'remove_copy_if', see 12.6.4 of Generic Programming && STL).
Since the STL already exist for more than a decade, it must be my own
mind which interprets the function name wrong. Or it is indeed a
friday afternoon issue. Of course human language is multiple
interpretable and English is not my native language, so the original c+
+ committee members may be 'right' after all.
Above functionality is solvable btw by stable_partition as someone
pointed out in CUJ.
