Test if tasks exist — rrq_task

Test if task ids exist (i.e., are known to this controller). Nonexistent tasks may be deleted, known to a different controller or just never have existed.

Usage

rrq_task_exists(task_ids, named = FALSE, controller = NULL)

Arguments

task_ids: Vector of task ids to check
named: Logical, indicating if the return value should be named with the task ids; as these are quite long this can make the value a little awkward to work with.
controller: The controller to use. If not given (or NULL) we'll use the controller registered with rrq_default_controller_set().

Value

A logical vector the same length as task_ids; TRUE where the task exists, FALSE otherwise. If named was TRUE, then this vector is named with task_ids.

Examples

obj <- rrq_controller("rrq:example")

t1 <- rrq_task_create_expr(runif(1), controller = obj)
rrq_task_exists(t1, controller = obj)
#> [1] TRUE

t2 <- ids::random_id()
rrq_task_exists(t2, controller = obj)
#> [1] FALSE
