List of task objects.
class task_list;
#include "tbb/task.h"
A task_list is a list of references to task objects. The purpose of task_list is to allow a task to create a list of tasks and spawn them all at once via the method task::spawn(task_list&), as described in Section static void spawn ( task_list& list ).
A task can belong to at most one task_list at a time, and on that task_list at most once. A task that has been spawned, but not started running, must not belong to a task_list. A task_list cannot be copy-constructed or assigned.
namespace tbb { class task_list { public: task_list(); ~task_list(); bool empty() const; void push_back( task& task ); task& pop_front(); void clear(); }; }
