-** Enumerable::Enumerator(Class)
-
-A class which provides a method `each' to be used as an Enumerable
-object.
-
-Superclass: Object
-
-Mix-ins: Enumerable
-
-require 'enumerator'
-
-Class Methods:
-
- new(obj, method = :each, *args)
-
- Creates a new Enumerable::Enumerator object, which is to be
- used as an Enumerable object using the given object's given
- method with the given arguments.
-
- e.g.:
- str = "xyz"
-
- enum = Enumerable::Enumerator.new(str, :each_byte)
- a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
-Methods:
-
- each {...}
-
- Iterates the given block using the object and the method
- specified in the first place.
-
-
-Requiring this module also adds some methods to the Object class:
-
- to_enum(method = :each, *args)
- enum_for(method = :each, *args)
-
- Returns Enumerable::Enumerator.new(self, method, *args).
-
- e.g.:
- str = "xyz"
-
- enum = str.enum_for(:each_byte)
- a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
- # protects an array from being modified
- a = [1, 2, 3]
- some_method(a.to_enum)
-
-And the Enumerable module.
-
- each_slice(n) {...}
-
- Iterates the given block for each slice of <n> elements.
-
- e.g.:
- (1..10).each_slice(3) {|a| p a}
- # outputs below
- [1, 2, 3]
- [4, 5, 6]
- [7, 8, 9]
- [10]
-
- enum_slice(n)
-
- Returns Enumerable::Enumerator.new(self, :each_slice, n).
-
- each_cons(n) {...}
-
- Iterates the given block for each array of consecutive <n>
- elements.
-
- e.g.:
- (1..10).each_cons(3) {|a| p a}
- # outputs below
- [1, 2, 3]
- [2, 3, 4]
- [3, 4, 5]
- [4, 5, 6]
- [5, 6, 7]
- [6, 7, 8]
- [7, 8, 9]
- [8, 9, 10]
-
- enum_cons(n)
-
- Returns Enumerable::Enumerator.new(self, :each_cons, n).
-
- enum_with_index
-
- Returns Enumerable::Enumerator.new(self, :each_with_index).
