[jira] Created: (TUSCANY-1139) [SDO for C++] Use x.push_back(y) rather than x.insert(x.end(), y)

[SDO for C++] Use x.push_back(y) rather than x.insert(x.end(), y)
-----------------------------------------------------------------

                 Key: TUSCANY-1139
                 URL: https://issues.apache.org/jira/browse/TUSCANY-1139
             Project: Tuscany
          Issue Type: Improvement
          Components: C++ SDO
    Affects Versions: Cpp-current
         Environment: All
            Reporter: Geoff Winn
         Assigned To: Geoff Winn
             Fix For: Cpp-current


There are numerous places in the code where an item is appended to the end of a list or vector using code similar to 

vector.insert(vector.end(), new_item);

This is less efficient than the preferred form which is

vector.push_back(new_item);

The performance impact of this is visible on Linux platforms using callgrind.
