class protocol_switch_factory :string -> (string * Netplex_types.processor_factory) list ->Netplex_types.processor_factory
protocol_switch_factory name merge_list: Merges the factories
in merge_list to a single factory. Which factory is selected
depends on the protocol.
For example:
service {
name = "...";
protocol {
name = "A"; ...;
}
protocol {
name = "B"; ...;
}
processor {
type = "merged";
A {
...
}
B {
...
}
}
}
Here, two protocols A and B are defined, and there is a
subsection in processor for each of the protocols configuring
the used service. "merged" is the name of the merged factories.
For example, A could be an RPC interface, and B could be
an HTTP interface providing the same service.
For every protocol in merge_list there must be a subsection in
processor for the protocol. This subsection configures then
the processor. It is not an error not to create sockets for
a protocol in merge_list.
