nextstream retrieves the currently stored L'Ecuyer-CMRG RNG stream
for the specified compute profile and advances it to the next stream.
nextget retrieves the specified item from the specified compute profile.
nextcode translates integer exit codes returned by daemon().
Arguments
- .compute
(character) name of the compute profile. Each profile has its own independent set of daemons.
NULL(default) uses the 'default' profile.- x
(character) item to retrieve:
"n"(daemon count),"dispatcher"(dispatcher-to-host URL),"url"(daemon connection URL), or"tls"(client TLS configuration).- xc
(integer) return value from
daemon().
Value
For nextstream: a length 7 integer vector, as given by
.Random.seed when the L'Ecuyer-CMRG RNG is in use (may be passed directly
to the rs argument of daemon()), or else NULL if a stream has not yet
been created.
For nextget: the requested item, or else NULL if not present.
For nextcode: character string.
Details
These functions are exported for use by packages extending mirai with
alternative launchers of daemon() processes.
For nextstream: This function should be called for its return value
when required. The function also has the side effect of automatically
advancing the stream stored within the compute profile. This ensures that the
next recursive stream is returned when the function is called again.
