Results for: "String# "

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.

Rinda error base class

Since RSS is based on XML, it must have opening and closing tags that match. If they don’t, a MissingTagError will be raised.

Installs a gem along with all its dependencies from local and remote gems.

The installer installs the files contained in the .gem into the Gem.home.

Gem::Installer does the work of putting files in all the right places on the filesystem including unpacking the gem into its gem dir, installing the gemspec in the specifications dir, storing the cached gem in the cache dir, and installing either wrappers or symlinks for executables.

The installer invokes pre and post install hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_install and Gem.post_install for details.

An Uninstaller.

The uninstaller fires pre and post uninstall hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_uninstall and Gem.post_uninstall for details.

Gem::StreamUI implements a simple stream based user interface.

Not a URI.

This module provides instance methods for a digest implementation object to calculate message digest values.

Used to construct C classes (CUnion, CStruct, etc)

Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.

Mixin methods for install and update options for Gem::Commands

When rubygems/test_case is required the default user interaction is a MockGemUi.

Module that defines the default UserInteraction. Any class including this module will have access to the ui method that returns the default UI.

UserInteraction allows RubyGems to interact with the user through standard methods that can be replaced with more-specific UI methods for different displays.

Since UserInteraction dispatches to a concrete UI class you may need to reference other classes for specific behavior such as Gem::ConsoleUI or Gem::SilentUI.

Example:

class X
  include Gem::UserInteraction

  def get_answer
    n = ask("What is the meaning of life?")
  end
end

Defines ParserWriterChooseMixin, which makes it possible to choose a different XMLWriter and/or XMLParser then the default one.

The Mixin is used in client.rb (class XMLRPC::Client) and server.rb (class XMLRPC::BasicServer)

Numeric is the class from which all higher-level numeric classes should inherit.

Numeric allows instantiation of heap-allocated objects. Other core numeric classes such as Integer are implemented as immediates, which means that each Integer is a single immutable object which is always passed by value.

a = 1
puts 1.object_id == a.object_id   #=> true

There can only ever be one instance of the integer 1, for example. Ruby ensures this by preventing instantiation and duplication.

Integer.new(1)   #=> NoMethodError: undefined method `new' for Integer:Class
1.dup            #=> TypeError: can't dup Fixnum

For this reason, Numeric should be used when defining other numeric classes.

Classes which inherit from Numeric must implement coerce, which returns a two-member Array containing an object that has been coerced into an instance of the new class and self (see coerce).

Inheriting classes should also implement arithmetic operator methods (+, -, * and /) and the <=> operator (see Comparable). These methods may rely on coerce to ensure interoperability with instances of other numeric classes.

class Tally < Numeric
  def initialize(string)
    @string = string
  end

  def to_s
    @string
  end

  def to_i
    @string.size
  end

  def coerce(other)
    [self.class.new('|' * other.to_i), self]
  end

  def <=>(other)
    to_i <=> other.to_i
  end

  def +(other)
    self.class.new('|' * (to_i + other.to_i))
  end

  def -(other)
    self.class.new('|' * (to_i - other.to_i))
  end

  def *(other)
    self.class.new('|' * (to_i * other.to_i))
  end

  def /(other)
    self.class.new('|' * (to_i / other.to_i))
  end
end

tally = Tally.new('||')
puts tally * 2            #=> "||||"
puts tally > 1            #=> true
