Creates a new Resolv::Hosts, using filename for its data source.
Creates a new DNS resolver.
config_info can be:
Uses /etc/resolv.conf.
StringPath to a file using /etc/resolv.conf’s format.
HashMust contain :nameserver, :search and :ndots keys.
:nameserver_port can be used to specify port number of nameserver address.
The value of :nameserver should be an address string or an array of address strings.
:nameserver => ‘8.8.8.8’
:nameserver => [‘8.8.8.8’, ‘8.8.4.4’]
The value of :nameserver_port should be an array of pair of nameserver address and port number.
:nameserver_port => [[‘8.8.8.8’, 53], [‘8.8.4.4’, 53]]
Example:
Resolv::DNS.new(:nameserver => ['210.251.121.21'], :search => ['ruby-lang.org'], :ndots => 1)
Creates a new one-shot Multicast DNS (mDNS) resolver.
config_info can be:
Uses the default mDNS addresses
HashMust contain :nameserver or :nameserver_port like Resolv::DNS#initialize.
Creates a new DRbObjectTemplate that will match against uri and ref.
Creates a new TupleSpaceProxy to wrap ts.
Creates a new SimpleRenewer that keeps an object alive for another sec seconds.
Advertises ts on the given addresses at port.
If addresses is omitted only the UDP broadcast address is used.
addresses can contain multiple addresses. If a multicast address is given in addresses then the RingServer will listen for multicast queries.
If you use IPv4 multicast you may need to set an address of the inbound interface which joins a multicast group.
ts = Rinda::TupleSpace.new rs = Rinda::RingServer.new(ts, [['239.0.0.1', '9.5.1.1']])
You can set addresses as an Array Object. The first element of the Array is a multicast address and the second is an inbound interface address. If the second is omitted then ‘0.0.0.0’ is used.
If you use IPv6 multicast you may need to set both the local interface address and the inbound interface index:
rs = Rinda::RingServer.new(ts, [['ff02::1', '::1', 1]])
The first element is a multicast address and the second is an inbound interface address. The third is an inbound interface index.
At this time there is no easy way to get an interface index by name.
If the second is omitted then ‘::1’ is used. If the third is omitted then 0 (default interface) is used.
Creates a new RingFinger that will look for RingServers at port on the addresses in broadcast_list.
If broadcast_list contains a multicast address then multicast queries will be made using the given multicast_hops and multicast_interface.
Creates a RingProvider that will provide a klass service running on front, with a description. renewer is optional.
Creates a TupleEntry based on ary with an optional renewer or expiry time sec.
A renewer must implement the renew method which returns a Numeric, nil, or true to indicate when the tuple has expired.
Creates a new NotifyTemplateEntry that watches place for +event+s that match tuple.
Creates a new TupleSpace. period is used to control how often to look for dead tuples after modifications to the TupleSpace.
If no dead tuples are found period seconds after the last modification, the TupleSpace will stop looking for dead tuples.
Initializes a generic gem command named command. summary is a short description displayed in ‘gem help commands`. defaults are the default options. Defaults should be mirrored in defaults_str, unless there are none.
When defining a new command subclass, use add_option to add command-line switches.
Unhandled arguments (gem names, files, etc.) are left in options[:args].
Register all the subcommands supported by the gem command.
Create the config file object. args is the list of arguments from the command line.
The following command line options are handled early here rather than later at the time most command options are processed.
--config-file, --config-file==NAMEObviously these need to be handled by the ConfigFile object to ensure we get the right config file.
--backtraceBacktrace needs to be turned on early so that errors before normal option parsing can be properly handled.
--debugEnable Ruby level debug messages. Handled early for the same reason as –backtrace.
