stop_mirai {mirai}

mirai (Stop)

Description

Stops a ‘mirai’ if still in progress, causing it to resolve immediately to an ‘errorValue’ 20 (Operation canceled).

Usage

stop_mirai(x)

Arguments

x

a ‘mirai’ object, or list of ‘mirai’ objects.

Details

Forces the ‘mirai’ to resolve immediately. Has no effect if the ‘mirai’ has already resolved.

If cancellation was successful, the value at $data will be an ‘errorValue’ 20 (Operation canceled). Note that in such a case, the ‘mirai’ has been aborted and the value not retrieved - but any ongoing evaluation in the daemon process will continue to completion and is not interrupted.

Value

Invisible NULL.

Examples

if (interactive()) {
# Only run examples in interactive R sessions

m <- mirai(Sys.sleep(n), n = 5)
stop_mirai(m)
m$data

}
