# class DRb::GWIdConv

Gateway id conversion forms a gateway between different `DRb` protocols or networks.

The gateway needs to install this id conversion and create servers for each of the protocols or networks it will be a gateway between. It then needs to create a server that attaches to each of these networks. For example:

    require 'drb/drb'
    require 'drb/unix'
    require 'drb/gw'

    DRb.install_id_conv DRb::GWIdConv.new
    gw = DRb::GW.new
    s1 = DRb::DRbServer.new 'drbunix:/path/to/gateway', gw
    s2 = DRb::DRbServer.new 'druby://example:10000', gw

    s1.thread.join
    s2.thread.join

Each client must register services with the gateway, for example:

    DRb.start_service 'drbunix:', nil # an anonymous server
    gw = DRbObject.new nil, 'drbunix:/path/to/gateway'
    gw[:unix] = some_service
    DRb.thread.join
