Module: Enumerable (Ruby 2.1.3)
The Enumerable mixin provides collection classes with several traversal and searching methods, and with the ability to sort. The class must provide a method each, which yields successive members of the collection. If Enumerable#max, #min, or #sort is used, the objects in the collection must also implement a meaningful <=> operator, as these methods rely on an ordering between members of the collec
Class: Thread (Ruby 2.1.3)
Threads are the Ruby implementation for a concurrent programming model. Programs that require multiple threads of execution are a perfect candidate for Ruby's Thread class. For example, we can create a new thread separate from the main thread's execution using ::new. thr = Thread.new { puts "Whats the big deal" } Then we are able to pause the execution of the main thread and allow our new thread t
Class: Exception (Ruby 2.1.3)
Descendants of class Exception are used to communicate between Kernel#raise and rescue statements in begin ... end blocks. Exception objects carry information about the exception – its type (the exception's class name), an optional descriptive string, and optional traceback information. Exception subclasses may add additional information like NameError#name. Programs may make subclasses of Excepti
Class: Module (Ruby 2.1.3)
A Module is a collection of methods and constants. The methods in a module may be instance methods or module methods. Instance methods appear as methods in a class when the module is included, module methods do not. Conversely, module methods may be called without creating an encapsulating object, while instance methods may not. (See Module#module_function) In the descriptions that follow, the par
