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!"
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 public 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 protected def method2() end end class C < B include A def method3() end end A.method_defined? :method1 #=> true C.public_method_defined? "method1" #=> true C.public_method_defined? "method2" #=> false C.method_defined? "method2" #=> true
Returns true
if the named protected 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 protected def method2() end end class C < B include A def method3() end end A.method_defined? :method1 #=> true C.protected_method_defined? "method1" #=> false C.protected_method_defined? "method2" #=> true C.method_defined? "method2" #=> true
Makes a list of existing class methods public.
String arguments are converted to symbols.
Returns the array of WIN32OLE_METHOD
object . The element of the array is property (gettable) of WIN32OLE
object.
excel = WIN32OLE.new('Excel.Application') properties = excel.ole_get_methods
Returns the array of WIN32OLE_METHOD
object . The element of the array is property (settable) of WIN32OLE
object.
excel = WIN32OLE.new('Excel.Application') properties = excel.ole_put_methods
Returns the array of WIN32OLE_METHOD
object . The element of the array is property (settable) of WIN32OLE
object.
excel = WIN32OLE.new('Excel.Application') properties = excel.ole_func_methods
Returns WIN32OLE_METHOD
object corresponding with method specified by 1st argument.
excel = WIN32OLE.new('Excel.Application') method = excel.ole_method_help('Quit')
Returns the size of optional parameters.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') puts method.size_opt_params # => 4
Invoked as a callback whenever a singleton method is added to the receiver.
module Chatty def Chatty.singleton_method_added(id) puts "Adding #{id.id2name}" end def self.one() end def two() end def Chatty.three() end end
produces:
Adding singleton_method_added Adding one Adding three
Invoked as a callback whenever a singleton method is removed from the receiver.
module Chatty def Chatty.singleton_method_removed(id) puts "Removing #{id.id2name}" end def self.one() end def two() end def Chatty.three() end class << self remove_method :three remove_method :one end end
produces:
Removing three Removing one
Invoked as a callback whenever a singleton method is undefined in the receiver.
module Chatty def Chatty.singleton_method_undefined(id) puts "Undefining #{id.id2name}" end def Chatty.one() end class << self undef_method(:one) end end
produces:
Undefining one
