cancel_task_after

task_id -> A task ID opts -> Can be:

• name: name | pid: pid -> Specify a non-global task handler, if unspecified that the application :global_name must be specified
• call_timeout: timeout -> Override the timeout on calling to the TaskAfter.Worker
• no_return: true -> Do not return the id or error, just try to register and forget results otherwise
• run_result: pid -> Sends the result of the task to the specified pid after running it as an async task while returning the Task
• run_result: :in_process -> Runs the task in the TaskAfter.Worker process to do internal work, do not use this, returns the value directly though
• run_result: :async -> Runs the task as an async task and dismisses the result while returning the Task
• run_result: nil -> Default: Does not run the task now, just cancels it immediately, returns the callback function

Examples

iex> cb = fn -> 42 end
iex> {:ok, auto_id} = TaskAfter.task_after(500, cb)
iex> {:ok, ^cb} = TaskAfter.cancel_task_after(auto_id)
iex> is_function(cb, 0)
true

change_task_after

task_id -> A task ID opts -> Can be:

• name: name | pid: pid -> Specify a non-global task handler, if unspecified that the application :global_name must be specified
• call_timeout: timeout -> Override the timeout on calling to the TaskAfter.Worker*no_return: true-> Do not return the id or error, just try to register and forget results otherwise *callback: fun-> Change the callback to this function *timeout_after_ms: timeout-> Change the timeout to this new value *send_result: pid-> Sends the result of the task to the specified pid after running it as an async task *send_result: :in_process-> Runs the task in the [TaskAfter.Worker](TaskAfter.Worker.html) process to do internal work, do not use this *send_result: :async-> **Default**: Runs the task as an async task and dismisses the result *recreate: true-> If this is passed in thencallback,timeout_after_ms, andsend_result**must** be specified to be able to recreate the task if it is already elapsed. Note: Of course if the task has already run then changing a setting on it won't do anything unlessrecreate: trueis passed in. Note: Whenrecreate: trueis used thencallback,timeout_after_ms, andsend_resultcan be passed in their value wrapped in a tagged:defaulttuple liketimeout_after_ms: {:default, 500}` and it will not change the existing value if not recreating but will use the value if it is. ## Examples iex> {:ok, auto_id} = TaskAfter.task_after(200, fn -> 1 end, send_result: self()) iex> {:ok, ^auto_id} = TaskAfter.change_task_after(auto_id, callback: fn -> 2 end) iex> assert_receive(2, 300) iex> receive do m -> m after 1 -> :no_message end :no_message

task_after

timeout_after_ms -> integer millisecond timeout callback -> The 0-argcallback function opts -> Can be:

• name: name | pid: pid -> Specify a non-global task handler, if unspecified that the application :global_name must be specified
• id: id -> A unique id, if nil or unspecified then it is auto-generated
• call_timeout: timeout -> Override the timeout on calling to the TaskAfter.Worker
• no_return: true -> Do not return the id or error, just try to register and forget results otherwise
• send_result: pid -> Sends the result of the task to the specified pid after running it as an async task
• send_result: :in_process -> Runs the task in the TaskAfter.Worker process to do internal work, do not use this
• send_result: :async -> Default: Runs the task as an async task and dismisses the result

Examples

iex> {:ok, _auto_id} = TaskAfter.task_after(500, fn -> 21 end)
iex> :ok
:ok

iex> {:ok, :myid} = TaskAfter.task_after(500, fn -> 42 end, send_result: self(), id: :myid)
iex> receive do m -> m after 5 -> :blah end
:blah
iex> receive do m -> m after 1000 -> :blah end
42
