gem implementation Returns a value representing the “cost” of transforming str1 into str2
Terminates the RubyGems process with the given exit_code
Normalizes a request path. Raises an exception if the path cannot be normalized.

Creates TCP server sockets bound to address

Processes the topmost available {RequirementState} on the stack @return [void]
@return [ResolutionState] the state whose ‘requirement` is the given
`requirement`.
Attempts to activate the current {#possibility} @return [void]
Generates a valid JSON
document from object obj
and returns the result. If no valid JSON
document can be created this method raises a GeneratorError
exception.
Returns the generator of the group.
See the OpenSSL
documentation for EC_GROUP_get0_generator()
Tags the current state of the dependency as the given tag @param [Object] tag an opaque tag for the current state of the graph @return [Void]
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
Returns a list of the public instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Returns a list of the protected instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Similar to instance_method, searches public method only.
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 detail information of type of argument.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'IWorksheetFunction') method = WIN32OLE_METHOD.new(tobj, 'SumIf') param1 = method.params[0] p param1.ole_type_detail # => ["PTR", "USERDEFINED", "Range"]
