Instances

PortRegistry PortRegistryData

PortRegistry PortRegistryPort

GenericRegistry

data GenericRegistry

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.
