Configure this State instance with the Hash opts, and return itself.

Writes data onto the IO, raising a FileOverflow exception if the number of bytes will be more than limit

Writes data onto the IO

Returns the value of the given instance variable, or nil if the instance variable is not set. The @ part of the variable name should be included for regular instance variables. Throws a NameError exception if the supplied symbol is not valid as an instance variable name. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_get(:@a)    #=> "cat"
fred.instance_variable_get("@b")   #=> 99

Sets the instance variable named by symbol to the given object, thereby frustrating the efforts of the class’s author to attempt to provide proper encapsulation. The variable does not have to exist prior to this call. If the instance variable name is passed as a string, that string is converted to a symbol.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_set(:@a, 'dog')   #=> "dog"
fred.instance_variable_set(:@c, 'cat')   #=> "cat"
fred.inspect                             #=> "#<Fred:0x401b3da8 @a=\"dog\", @b=99, @c=\"cat\">"

Returns true if the given instance variable is defined in obj. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_defined?(:@a)    #=> true
fred.instance_variable_defined?("@b")   #=> true
fred.instance_variable_defined?("@c")   #=> false

Removes the named instance variable from obj, returning that variable’s value.

class Dummy
  attr_reader :var
  def initialize
    @var = 99
  end
  def remove
    remove_instance_variable(:@var)
  end
end
d = Dummy.new
d.var      #=> 99
d.remove   #=> 99
d.var      #=> nil

Re-composes a prime factorization and returns the product.

See Prime#int_from_prime_division for more details.

Returns a list of the private instance methods defined in mod. If the optional parameter is false, the methods of any ancestors are not included.

module Mod
  def method1()  end
  private :method1
  def method2()  end
end
Mod.instance_methods           #=> [:method2]
Mod.private_instance_methods   #=> [:method1]

Removes the definition of the sym, returning that constant’s value.

class Dummy
  @@var = 99
  puts @@var
  remove_class_variable(:@@var)
  p(defined? @@var)
end

produces:

99
nil

Returns the value of the given class variable (or throws a NameError exception). The @@ part of the variable name should be included for regular class variables. String arguments are converted to symbols.

class Fred
  @@foo = 99
end
Fred.class_variable_get(:@@foo)     #=> 99

Sets the class variable named by symbol to the given object. If the class variable name is passed as a string, that string is converted to a symbol.

class Fred
  @@foo = 99
  def foo
    @@foo
  end
end
Fred.class_variable_set(:@@foo, 101)     #=> 101
Fred.new.foo                             #=> 101

Returns true if the given class variable is defined in obj. String arguments are converted to symbols.

class Fred
  @@foo = 99
end
Fred.class_variable_defined?(:@@foo)    #=> true
Fred.class_variable_defined?(:@@bar)    #=> false

Returns true if the named private method is defined by _ mod_ (or its included modules and, if mod is a class, its ancestors). String arguments are converted to symbols.

module A
  def method1()  end
end
class B
  private
  def method2()  end
end
class C < B
  include A
  def method3()  end
end

A.method_defined? :method1            #=> true
C.private_method_defined? "method1"   #=> false
C.private_method_defined? "method2"   #=> true
C.method_defined? "method2"           #=> false

Makes existing class methods private. Often used to hide the default constructor new.

String arguments are converted to symbols.

class SimpleSingleton  # Not thread safe
  private_class_method :new
  def SimpleSingleton.create(*args, &block)
    @me = new(*args, &block) if ! @me
    @me
  end
end

Returns detail information of return value type of method. The information is array.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
p method.return_type_detail # => ["PTR", "USERDEFINED", "Workbook"]

Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer")
p tobj.source_ole_types
# => [#<WIN32OLE_TYPE:DWebBrowserEvents2>, #<WIN32OLE_TYPE:DWebBrowserEvents>]

Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE and IMPLTYPEFLAG_FDEFAULT.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer")
p tobj.default_event_sources  # => [#<WIN32OLE_TYPE:DWebBrowserEvents2>]
