Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.

Raised when the address is an invalid length.

ReadTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.

Represents SMTP error code 420 or 450, a temporary error.

Indicates a timeout resolving a name or address.

Represents a tagged XML element. Elements are characterized by having children, attributes, and names, and can themselves be children.

A class which provides filtering of children for Elements, and XPath search support. You are expected to only encounter this class as the element.elements object. Therefore, you are not expected to instantiate this yourself.

A parent has children, and has methods for accessing them. The Parent class is never encountered except as the superclass for some other object.

Templates are used to match tuples in Rinda.

An SimpleRenewer allows a TupleSpace to check if a TupleEntry is still alive.

A RingServer allows a Rinda::TupleSpace to be located via UDP broadcasts. Default service location uses the following steps:

1. A RingServer begins listening on the network broadcast UDP address.

2. A RingFinger sends a UDP packet containing the DRb URI where it will listen for a reply.

3. The RingServer receives the UDP packet and connects back to the provided DRb URI with the DRb service.

A RingServer requires a TupleSpace:

ts = Rinda::TupleSpace.new
rs = Rinda::RingServer.new

RingServer can also listen on multicast addresses for announcements. This allows multiple RingServers to run on the same host. To use network broadcast and multicast:

ts = Rinda::TupleSpace.new
rs = Rinda::RingServer.new ts, %w[Socket::INADDR_ANY, 239.0.0.1 ff02::1]

RingProvider uses a RingServer advertised TupleSpace as a name service. TupleSpace clients can register themselves with the remote TupleSpace and look up other provided services via the remote TupleSpace.

Services are registered with a tuple of the format [:name, klass, DRbObject, description].

A TemplateEntry is a Template together with expiry and cancellation data.

Documentation?

A NotifyTemplateEntry is returned by TupleSpace#notify and is notified of TupleSpace changes. You may receive either your subscribed event or the ‘close’ event when iterating over notifications.

See TupleSpace#notify_event for valid notification types.

Example

ts = Rinda::TupleSpace.new
observer = ts.notify 'write', [nil]

Thread.start do
  observer.each { |t| p t }
end

3.times { |i| ts.write [i] }

Outputs:

['write', [0]]
['write', [1]]
['write', [2]]
