The typeclass for the PortRegistry. Contains all PortRegistry functions which can accessed remotely by the clients.

Synopsis
class PortRegistry pr where
registerPort :: String -> SocketId -> pr -> IO ()
unregisterPort :: String -> pr -> IO ()
lookupPort :: String -> pr -> IO (Maybe SocketId)
getPorts :: pr -> IO [(String, SocketId)]
data GenericRegistry
mkGenericRegistry :: PortRegistry r => r -> GenericRegistry
Type-Classes
class PortRegistry pr whereSource
The Interface of the PortRegistry.
Methods

Creates a new port entry in the registry.
unregisterPort :: String -> pr -> IO ()Source
Deletes an entry from the registry.
lookupPort :: String -> pr -> IO (Maybe SocketId)Source
Get the socket of the port by its name.
getPorts :: pr -> IO [(String, SocketId)]Source
Get a list of all registered ports.

GenericRegistry
data GenericRegistry Source
The generic registry object. This is a wrapper around an PortRegistryData or PortRegistryPort object. With this additional indirection, we eliminate the distinction between the port or the data object in the datatypes using the PortRegistry. Therefore it is easier to get access to the registry and the code gets more readable. This might be a good example of hiding network-access. To the caller it makes no difference, if the PortRegistry is in the same address space of on another computer in the network.
