Code Editor : object.rbs

# Object is the default root of all Ruby objects.  Object inherits from
# BasicObject which allows creating alternate object hierarchies.  Methods on
# Object are available to all classes unless explicitly overridden.
#
# Object mixes in the Kernel module, making the built-in kernel functions
# globally accessible.  Although the instance methods of Object are defined by
# the Kernel module, we have chosen to document them here for clarity.
#
# When referencing constants in classes inheriting from Object you do not need
# to use the full namespace.  For example, referencing `File` inside `YourClass`
# will find the top-level File class.
#
# In the descriptions of Object's methods, the parameter *symbol* refers to a
# symbol, which is either a quoted string or a Symbol (such as `:name`).
#
class Object < BasicObject
  include Kernel

# Returns true if two objects do not match (using the *=~* method), otherwise
  # false.
  #
  def !~: (untyped) -> bool

# Returns 0 if `obj` and `other` are the same object or `obj == other`,
  # otherwise nil.
  #
  # The `<=>` is used by various methods to compare objects, for example
  # Enumerable#sort, Enumerable#max etc.
  #
  # Your implementation of `<=>` should return one of the following values: -1, 0,
  # 1 or nil. -1 means self is smaller than other. 0 means self is equal to other.
  # 1 means self is bigger than other. Nil means the two values could not be
  # compared.
  #
  # When you define `<=>`, you can include Comparable to gain the methods `<=`,
  # `<`, `==`, `>=`, `>` and `between?`.
  #
  def <=>: (untyped) -> Integer?

# Case Equality -- For class Object, effectively the same as calling `#==`, but
  # typically overridden by descendants to provide meaningful semantics in `case`
  # statements.
  #
  def ===: (untyped) -> bool

# This method is deprecated.
  #
  # This is not only unuseful but also troublesome because it may hide a type
  # error.
  #
  def =~: (untyped) -> bool

# Returns the class of *obj*. This method must always be called with an explicit
  # receiver, as `class` is also a reserved word in Ruby.
  #
  #     1.class      #=> Integer
  #     self.class   #=> Object
  #
  def `class`: () -> untyped

# Produces a shallow copy of *obj*---the instance variables of *obj* are copied,
  # but not the objects they reference. `clone` copies the frozen (unless :freeze
  # keyword argument is given with a false value) and tainted state of *obj*. See
  # also the discussion under `Object#dup`.
  #
  #     class Klass
  #        attr_accessor :str
  #     end
  #     s1 = Klass.new      #=> #<Klass:0x401b3a38>
  #     s1.str = "Hello"    #=> "Hello"
  #     s2 = s1.clone       #=> #<Klass:0x401b3998 @str="Hello">
  #     s2.str[1,4] = "i"   #=> "i"
  #     s1.inspect          #=> "#<Klass:0x401b3a38 @str=\"Hi\">"
  #     s2.inspect          #=> "#<Klass:0x401b3998 @str=\"Hi\">"
  #
  # This method may have class-specific behavior.  If so, that behavior will be
  # documented under the #`initialize_copy` method of the class.
  #
  def clone: (?freeze: bool) -> self

# Defines a singleton method in the receiver. The *method* parameter can be a
  # `Proc`, a `Method` or an `UnboundMethod` object. If a block is specified, it
  # is used as the method body.
  #
  #     class A
  #       class << self
  #         def class_name
  #           to_s
  #         end
  #       end
  #     end
  #     A.define_singleton_method(:who_am_i) do
  #       "I am: #{class_name}"
  #     end
  #     A.who_am_i   # ==> "I am: A"
  #
  #     guy = "Bob"
  #     guy.define_singleton_method(:hello) { "#{self}: Hello there!" }
  #     guy.hello    #=>  "Bob: Hello there!"
  #
  def define_singleton_method: (Symbol, Method | UnboundMethod) -> Symbol
                             | (Symbol) { (*untyped) -> untyped } -> Symbol

# Prints *obj* on the given port (default `$>`). Equivalent to:
  #
  #     def display(port=$>)
  #       port.write self
  #       nil
  #     end
  #
  # For example:
  #
  #     1.display
  #     "cat".display
  #     [ 4, 5, 6 ].display
  #     puts
  #
  # *produces:*
  #
  #     1cat[4, 5, 6]
  #
  def display: (?_Writeable port) -> void

# Produces a shallow copy of *obj*---the instance variables of *obj* are copied,
  # but not the objects they reference. `dup` copies the tainted state of *obj*.
  #
  # This method may have class-specific behavior.  If so, that behavior will be
  # documented under the #`initialize_copy` method of the class.
  #
  # ### on dup vs clone
  #
  # In general, `clone` and `dup` may have different semantics in descendant
  # classes. While `clone` is used to duplicate an object, including its internal
  # state, `dup` typically uses the class of the descendant object to create the
  # new instance.
  #
  # When using #dup, any modules that the object has been extended with will not
  # be copied.
  #
  #     class Klass
  #       attr_accessor :str
  #     end
  #
  #     module Foo
  #       def foo; 'foo'; end
  #     end
  #
  #     s1 = Klass.new #=> #<Klass:0x401b3a38>
  #     s1.extend(Foo) #=> #<Klass:0x401b3a38>
  #     s1.foo #=> "foo"
  #
  #     s2 = s1.clone #=> #<Klass:0x401b3a38>
  #     s2.foo #=> "foo"
  #
  #     s3 = s1.dup #=> #<Klass:0x401b3a38>
  #     s3.foo #=> NoMethodError: undefined method `foo' for #<Klass:0x401b3a38>
  #
  def dup: () -> self

# Creates a new Enumerator which will enumerate by calling `method` on `obj`,
  # passing `args` if any.
  #
  # If a block is given, it will be used to calculate the size of the enumerator
  # without the need to iterate it (see Enumerator#size).
  #
  # ### Examples
  #
  #     str = "xyz"
  #
  #     enum = str.enum_for(:each_byte)
  #     enum.each { |b| puts b }
  #     # => 120
  #     # => 121
  #     # => 122
  #
  #     # protect an array from being modified by some_method
  #     a = [1, 2, 3]
  #     some_method(a.to_enum)
  #
  # It is typical to call to_enum when defining methods for a generic Enumerable,
  # in case no block is passed.
  #
  # Here is such an example, with parameter passing and a sizing block:
  #
  #     module Enumerable
  #       # a generic method to repeat the values of any enumerable
  #       def repeat(n)
  #         raise ArgumentError, "#{n} is negative!" if n < 0
  #         unless block_given?
  #           return to_enum(__method__, n) do # __method__ is :repeat here
  #             sz = size     # Call size and multiply by n...
  #             sz * n if sz  # but return nil if size itself is nil
  #           end
  #         end
  #         each do |*val|
  #           n.times { yield *val }
  #         end
  #       end
  #     end
  #
  #     %i[hello world].repeat(2) { |w| puts w }
  #       # => Prints 'hello', 'hello', 'world', 'world'
  #     enum = (1..14).repeat(3)
  #       # => returns an Enumerator when called without a block
  #     enum.first(4) # => [1, 1, 1, 2]
  #     enum.size # => 42
  #
  def enum_for: (Symbol method, *untyped args) ?{ (*untyped args) -> Integer } -> Enumerator[untyped, untyped]
              | (*untyped args) ?{ (*untyped args) -> Integer } -> Enumerator[untyped, untyped]

# Equality --- At the `Object` level, `==` returns `true` only if `obj` and
  # `other` are the same object. Typically, this method is overridden in
  # descendant classes to provide class-specific meaning.
  #
  # Unlike `==`, the `equal?` method should never be overridden by subclasses as
  # it is used to determine object identity (that is, `a.equal?(b)` if and only if
  # `a` is the same object as `b`):
  #
  #     obj = "a"
  #     other = obj.dup
  #
  #     obj == other      #=> true
  #     obj.equal? other  #=> false
  #     obj.equal? obj    #=> true
  #
  # The `eql?` method returns `true` if `obj` and `other` refer to the same hash
  # key.  This is used by Hash to test members for equality.  For objects of class
  # `Object`, `eql?` is synonymous with `==`.  Subclasses normally continue this
  # tradition by aliasing `eql?` to their overridden `==` method, but there are
  # exceptions.  `Numeric` types, for example, perform type conversion across
  # `==`, but not across `eql?`, so:
  #
  #     1 == 1.0     #=> true
  #     1.eql? 1.0   #=> false
  #
  def eql?: (untyped) -> bool

# Adds to *obj* the instance methods from each module given as a parameter.
  #
  #     module Mod
  #       def hello
  #         "Hello from Mod.\n"
  #       end
  #     end
  #
  #     class Klass
  #       def hello
  #         "Hello from Klass.\n"
  #       end
  #     end
  #
  #     k = Klass.new
  #     k.hello         #=> "Hello from Klass.\n"
  #     k.extend(Mod)   #=> #<Klass:0x401b3bc8>
  #     k.hello         #=> "Hello from Mod.\n"
  #
  def `extend`: (*Module) -> self

# Prevents further modifications to *obj*. A `RuntimeError` will be raised if
  # modification is attempted. There is no way to unfreeze a frozen object. See
  # also `Object#frozen?`.
  #
  # This method returns self.
  #
  #     a = [ "a", "b", "c" ]
  #     a.freeze
  #     a << "z"
  #
  # *produces:*
  #
  #     prog.rb:3:in `<<': can't modify frozen Array (FrozenError)
  #      from prog.rb:3
  #
  # Objects of the following classes are always frozen: Integer, Float, Symbol.
  #
  def freeze: () -> self

# Returns the freeze status of *obj*.
  #
  #     a = [ "a", "b", "c" ]

  def frozen?: () -> bool

def hash: () -> Integer

# Returns a string containing a human-readable representation of *obj*. The

# Mark the object as tainted.

  # Objects that are marked as tainted will be restricted from various built-in

  # system.
  #
  # To check whether an object is tainted, use #tainted?.
  #
  # You should only untaint a tainted object if your code has inspected it and
  # determined that it is safe. To do so use #untaint.

# Yields self to the block, and then returns self. The primary purpose of this

  #
  # Good usage for `yield_self` is value piping in method chains:

  # When called without block, the method returns `Enumerator`, which can be used,
  # for example, for conditional circuit-breaking:
  #
  #     # meets condition, no-op
  #     1.yield_self.detect(&:odd?)            # => 1
  #     # does not meet condition, drop value
