Detect if message has response — rrq_message_has_response • rrq

Detect if a response is available for a message

Usage

rrq_message_has_response(
  message_id,
  worker_ids = NULL,
  named = TRUE,
  controller = NULL
)

Arguments

message_id: The message id
worker_ids: Optional vector of worker ids. If NULL then all active workers are used (note that this may differ to the set of workers that the message was sent to!)
named: Logical, indicating if the return vector should be named
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, possibly named (depending on the named argument)

Examples

obj <- rrq_controller("rrq:example")

id <- rrq_message_send("PING", controller = obj)
rrq_message_has_response(id, controller = obj)
#> exhaustible_umbrette 
#>                FALSE 
rrq_message_get_response(id, timeout = 5, controller = obj)
#> $exhaustible_umbrette
#> [1] "PONG"
#> 
rrq_message_has_response(id, controller = obj)
#> exhaustible_umbrette 
#>                 TRUE
