rrq_task_preceeding

R Documentation

List tasks ahead of a task

Description

List the tasks in front of task_id in the queue. If the task is missing from the queue this will return NULL. If the task is next in the queue this will return an empty character vector.

Usage

rrq_task_preceeding(task_id, queue = NULL, follow = NULL, controller = NULL)

Arguments

`task_id`	Task to find the position for.
`queue`	The name of the queue to query (defaults to the "default" queue).
`follow`	Optional logical, indicating if we should follow any redirects set up by doing rrq_task_retry. If not given, falls back on the value passed into the controller, the global option `rrq.follow`, and finally `TRUE`. Set to `FALSE` if you want to return information about the original task, even if it has been subsequently retried.
`controller`	The controller to use. If not given (or `NULL`) we'll use the controller registered with `rrq_default_controller_set()`.
