Pool Hooks

Writing hooks

Hooks are written by creating a class or a struct which inherits from the class ThreadPool::Hooks. You can then override whichever hooks you need.

Tasks Hooks

.. doxygenfunction:: ThreadPool::Hooks::pre_task_hook()

.. doxygenfunction:: ThreadPool::Hooks::post_task_hook()

Workers Hooks

.. doxygenfunction:: ThreadPool::Hooks::on_worker_add()

.. doxygenfunction:: ThreadPool::Hooks::on_worker_die()

Registering hooks

Hooks can be used to be notified when actions happens in the pool. The hooks are registered in the pool using the function:

.. doxygenfunction:: ThreadPool::ThreadPool::register_hooks(std::shared_ptr<ThreadPool::Hooks>)

Example
