tf::WorkerView class
#include <taskflow/core/worker.hpp>

class to create an immutable view of a worker in an executor

An executor keeps a set of internal worker threads to run tasks. A worker view provides users an immutable interface to observe when a worker runs a task, and the view object is only accessible from an observer derived from tf::ObserverInterface.

Public functions

auto id() const -> size_t
queries the worker id associated with its parent executor
auto queue_size() const -> size_t
queries the size of the queue (i.e., number of pending tasks to run) associated with the worker
auto queue_capacity() const -> size_t
queries the current capacity of the queue

Function documentation

size_t tf::WorkerView::id() const

queries the worker id associated with its parent executor

A worker id is a unsigned integer in the range [0, N), where N is the number of workers spawned at the construction time of the executor.
