TupleSpaceProxy allows a remote Tuplespace to appear as local.
The Tuplespace manages access to the tuples it contains, ensuring mutual exclusion requirements are met.
The sec option for the write, take, move, read and notify methods may either be a number of seconds or a Renewer object.
Gem::DependencyList is used for installing and uninstalling gems in the correct order to avoid conflicts.
Raised when trying to activate a gem, and that gem does not exist on the system. Instead of rescuing from this class, make sure to rescue from the superclass Gem::LoadError to catch all types of load errors.
An error that indicates we weren’t able to fetch some data from a source
Base exception class for RubyGems. All exception raised by RubyGems are a subclass of this one.
Raised when attempting to uninstall a gem that isn’t in GEM_HOME.
Potentially raised when a specification is validated.
Used to raise parsing and loading errors
Raised by Gem::Validator when something is not right in a gem.
Raised to indicate that a system exit should occur with the specified exit_code
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 Specification class contains the information for a gem. Typically defined in a .gemspec file or a Rakefile, and looks like this:
Gem::Specification.new do |s| s.name = 'example' s.version = '0.1.0' s.licenses = ['MIT'] s.summary = "This is an example!" s.description = "Much longer explanation of the example!" s.authors = ["Ruby Coder"] s.email = 'rubycoder@example.com' s.files = ["lib/example.rb"] s.homepage = 'https://rubygems.org/gems/example' s.metadata = { "source_code_uri" => "https://github.com/example/example" } end
Starting in RubyGems 2.0, a Specification can hold arbitrary metadata. See metadata for restrictions on the format and size of metadata items you may add to a specification.
Gem::StubSpecification reads the stub: line from the gemspec. This prevents us having to eval the entire gemspec in order to find out certain information.
Validator performs various gem file and gem database validation

Not a URI component.
An internal representation of the backtrace. The user will never interact with objects of this class directly, but class methods can be used to get backtrace settings of the current session.
