module DRb::DRbProtocol

Public Class Methods

add_protocol(prot) Show source

# File lib/drb/drb.rb, line 725
def add_protocol(prot)
  @protocol.push(prot)
end

Add a new protocol to the DRbProtocol module.

open(uri, config, first=true) Show source

# File lib/drb/drb.rb, line 737
def open(uri, config, first=true)
  @protocol.each do |prot|
    begin
      return prot.open(uri, config)
    rescue DRbBadScheme
    rescue DRbConnError
      raise($!)
    rescue
      raise(DRbConnError, "#{uri} - #{$!.inspect}")
    end
  end
  if first && (config[:auto_load] != false)
    auto_load(uri)
    return open(uri, config, false)
  end
  raise DRbBadURI, 'can\t parse uri:' + uri
end

Open a client connection to uri with the configuration config.

The DRbProtocol module asks each registered protocol in turn to try to open the URI. Each protocol signals that it does not handle that URI by raising a DRbBadScheme error. If no protocol recognises the URI, then a DRbBadURI error is raised. If a protocol accepts the URI, but an error occurs in opening it, a DRbConnError is raised.

open_server(uri, config, first=true) Show source

# File lib/drb/drb.rb, line 765
def open_server(uri, config, first=true)
  @protocol.each do |prot|
    begin
      return prot.open_server(uri, config)
    rescue DRbBadScheme
    end
  end
  if first && (config[:auto_load] != false)
    auto_load(uri)
    return open_server(uri, config, false)
  end
  raise DRbBadURI, 'can\t parse uri:' + uri
end

Open a server listening for connections at uri with configuration config.

The DRbProtocol module asks each registered protocol in turn to try to open a server at the URI. Each protocol signals that it does not handle that URI by raising a DRbBadScheme error. If no protocol recognises the URI, then a DRbBadURI error is raised. If a protocol accepts the URI, but an error occurs in opening it, the underlying error is passed on to the caller.

uri_option(uri, config, first=true) Show source

# File lib/drb/drb.rb, line 786
def uri_option(uri, config, first=true)
  @protocol.each do |prot|
    begin
      uri, opt = prot.uri_option(uri, config)
      # opt = nil if opt == ''
      return uri, opt
    rescue DRbBadScheme
    end
  end
  if first && (config[:auto_load] != false)
    auto_load(uri)
    return uri_option(uri, config, false)
  end
  raise DRbBadURI, 'can\t parse uri:' + uri
end

Parse uri into a [uri, option] pair.

The DRbProtocol module asks each registered protocol in turn to try to parse the URI. Each protocol signals that it does not handle that URI by raising a DRbBadScheme error. If no protocol recognises the URI, then a DRbBadURI error is raised.
