The purpose of having two for-loops is just to provide a place to
|
||
|
|
declare both the iterator and value variables. There is really only
|
||
|
|
one loop. The stopping condition gets executed two more times than it
|
||
|
|
usually would be, oh well. The reason for the bgl_first_9 = bgl_last_9
|
||
|
|
in the outer for-loop is in case the user puts a break statement
|
||
|
|
in the inner for-loop.
|
||
|
|
|
||
|
|
The other macros work in a similar fashion.
|
||
|
|
|
||
|
|
Use the _T versions when the graph type is a template parameter or
|
||
|
|
dependent on a template parameter. Otherwise use the non _T versions.

The above contains two calls to the vertices function. I modified these

macros to expand to
