Detailed Description

template<typename RT = void>
class Threads::TaskGroup< RT >

A container for task objects. Allows to add new task objects and wait for them all together. The task objects need to have the same return value for the called function.

Note that the call to join_all() must be executed on the same thread as the calls that add subtasks. Otherwise, there might be a deadlock. In other words, a Task object should never passed on to another task for calling the join() method.

Member Function Documentation

◆ operator+=()

template<typename RT = void>
TaskGroup& Threads::TaskGroup< RT >::operator+= ( const Task< RT > &  t)
inline

Add another task object to the collection.

◆ join_all()

template<typename RT = void>
void Threads::TaskGroup< RT >::join_all ( ) const
inline

Wait for all tasks in the collection to finish. It is not a problem if some of them have already been waited for, i.e. you may call this function more than once, and you can also add new task objects between subsequent calls to this function if you want.
