This class provides a threadsafe version of
OEDots. Multiple threads can call
OEThreadedDots::Update to update the progress
in an efficient manner in a thread-safe way. This class will create
an internal operating system thread to handle output to
OEPlatform::oeerr. The complete progress is
not guaranteed to be output to the terminal until
OEThreadedDots::Total is called.
OEThreadedDots(unsigned int bigstep, unsigned int smallstep, const char *objectname="")
Controls how the following output gets updated:
.......... 10000 things processed. .......... 20000 things processed. .......... 30000 things processed. .......... 40000 things processed. .......... 50000 things processed. .......... 60000 things processed. .......... 70000 things processed. .......... 80000 things processed.
The number of elements before a new line is generated. The above example is a
The number of elements before a single new dot,
., is printed. The above example is a
1000. Or 10 dots per line.
A description of what is being processed. In the above example, this is “things”.
Prints a final summary line like the following:
Total: 80000 things processed.
Calling this method waits for all information to flush to the IO thread and then terminates and joins that thread. So this function is effectively a blocking call on those operations. But the operations are typically very cheap, so the blocking nature is not noticeable.
void Update(unsigned int step=1)
Update the progress with the number of elements specified by
step. The default is
1 element, but any number can be
0 is not a valid step size and will
throw an error.
OEThreadedDots, this method is
thread-safe to call from multiple threads even though it is a
