Subject: Performance optimization: empty() instead of size()>0
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=b27eb2571c2e87d1e43a6ee4e47aea066fc47f02;p=flightgear.git

Performance optimization: empty() instead of size()>0

empty() is guaranteed to be constant complexity for both vectors and lists, while size() has linear complexity for lists.
