3 Migrating from low-level task API
6 The low-level task API of Intel(R) Threading Building Blocks (TBB) was considered complex and hence
9 task API is used.
17 inherit ``tbb::task`` and implement its interface. Then spawning of ``ChildTask1`` and

27         RootTask& root = *new(tbb::task::allocate_root()) RootTask{};
34         tbb::task::spawn(child1);
35         tbb::task::spawn(child2);
58 implement ``tbb::task`` interface that overrides the ``tbb::task* tbb::task::execute()`` virtual

96 parallel pattern. The ``tbb::parallel_do`` algorithm logic may be implemented using the task API as:
102     #include <tbb/task.h>
104     // Assuming RootTask and OtherWork are defined and implement tbb::task interface.
106     struct Task : public tbb::task {
107         Task(tbb::task& root, int i)
111         tbb::task* execute() override {
115                 tbb::task& child = *new(m_root.allocate_child()) OtherWork;
116                 tbb::task::spawn(child);
121         tbb::task& m_root;
127         RootTask& root = *new(tbb::task::allocate_root()) RootTask{/*params*/};
132             Task& task = *new(root.allocate_child()) Task(root, items[i]);
133             tbb::task::spawn(task);
