Access.Control.Concurrent.Chan
Documentation
module Control.Concurrent.Chan
class Access io => ChanAccess io where Source
Methods
newChan' :: io (Chan a) Source
Build and returns a new instance of Chan.
writeChan' :: Chan a -> a -> io () Source
Write a value to a Chan.
readChan' :: Chan a -> io a Source
Read the next value from the Chan.
dupChan' :: Chan a -> io (Chan a) Source
Duplicate a Chan: the duplicate channel begins empty, but data written to
either channel from then on will be available from both. Hence this creates
a kind of broadcast channel, where data written by anyone is seen by
everyone else.
(Note that a duplicated channel is not equal to its original.
So: fmap (c /=) $ dupChan c returns True for all c.)
getChanContents' :: Chan a -> io [a] Source
Return a lazy list representing the contents of the supplied
Chan, much like hGetContents.
writeList2Chan' :: Chan a -> [a] -> io () Source
Write an entire list of items to a Chan.
