The writer adapter class
An abstract class for enumerating pseudo-prime numbers.
Concrete subclasses should override succ, next, rewind.
An implementation of PseudoPrimeGenerator which uses a prime table generated by trial division.
Internal use. An implementation of prime table by trial division method.
Defines an Element Attribute; IE, a attribute=value pair, as in: <element attribute=“value”/>. Attributes can be in their own namespaces. General users of REXML will not interact with the Attribute class much.
A class that defines the set of Attributes of an Element and provides operations for accessing elements in that set.
Generates Source-s. USE THIS CLASS.
A Source can be searched for patterns, and wraps buffers and other objects and provides consumption of text
Rinda error base class
A RingServer allows a Rinda::TupleSpace to be located via UDP broadcasts. Default service location uses the following steps:
A RingServer begins listening on the network broadcast UDP address.
A RingFinger sends a UDP packet containing the DRb URI where it will listen for a reply.
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]
RingFinger is used by RingServer clients to discover the RingServer’s TupleSpace. Typically, all a client needs to do is call RingFinger.primary to retrieve the remote TupleSpace, which it can then begin using.
To find the first available remote TupleSpace:
Rinda::RingFinger.primary
To create a RingFinger that broadcasts to a custom list:
rf = Rinda::RingFinger.new ['localhost', '192.0.2.1'] rf.primary
Rinda::RingFinger also understands multicast addresses and sets them up properly. This allows you to run multiple RingServers on the same host:
rf = Rinda::RingFinger.new ['239.0.0.1'] rf.primary
You can set the hop count (or TTL) for multicast searches using multicast_hops.
If you use IPv6 multicast you may need to set both an address and the outbound interface index:
rf = Rinda::RingFinger.new ['ff02::1'] rf.multicast_interface = 1 rf.primary
At this time there is no easy way to get an interface index by name.
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].
Certain attributes are required on specific tags in an RSS feed. If a feed is missing one of these attributes, a MissingAttributeError is raised.
An error that indicates we weren’t able to fetch some data from a source
Represents an error communicating via HTTP.
Raised by Gem::Validator when something is not right in a gem.
A Source knows how to list and fetch gems from a RubyGems marshal index.
There are other Source subclasses for installed gems, local gems, the bundler dependency API and so-forth.
The SourceList represents the sources rubygems has been configured to use. A source may be created from an array of sources:
Gem::SourceList.from %w[https://rubygems.example https://internal.example]
Or by adding them:
sources = Gem::SourceList.new sources << 'https://rubygems.example'
The most common way to get a SourceList is Gem.sources.
