Fetch value associated with a variable from the shared netWorkSpace.
1 2 | ## S4 method for signature 'netWorkSpace'
nwsFetch(.Object, xName)
|
.Object |
a netWorkSpace class object |
xName |
name of the variable to be fetched |
The nwsFetch
method looks in the shared netWorkSpace .Object
for a value bound to xName
; if it finds such a value, nwsFetch
returns it and removes it from the variable. If no value is found, nwsFetch
blocks until a value for xName
becomes available.
This operation is atomic. If there are multiple nwsFetch
or
nwsFetchTry
requests for a given xName
, any given value from
the set of values associated with xName
will be returned to just one requester.
If there is more than one value associated with xName
, the particular
value removed depends on xName
's behavior. See nwsDeclare
for details.
