Returns an Addrinfo object for remote address obtained by getpeername.

Note that addrinfo.protocol is filled by 0.

TCPSocket.open("www.ruby-lang.org", 80) {|s|
  p s.remote_address #=> #<Addrinfo: 221.186.184.68:80 TCP>
}

TCPServer.open("127.0.0.1", 1728) {|serv|
  c = TCPSocket.new("127.0.0.1", 1728)
  s = serv.accept
  p s.remote_address #=> #<Addrinfo: 127.0.0.1:36504 TCP>
}

Invokes Release method of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE. The return value is reference counter of OLE object.

invokes Release method of Dispatch interface of WIN32OLE object. Usually, you do not need to call this method because Release method called automatically when WIN32OLE object garbaged.

Calls WIN32OLE#invoke method.

Returns WIN32OLE_TYPE object.

excel = WIN32OLE.new('Excel.Application')
tobj = excel.ole_type

Returns the WIN32OLE_TYPELIB object. The object represents the type library which contains the WIN32OLE object.

excel = WIN32OLE.new('Excel.Application')
tlib = excel.ole_typelib
puts tlib.name  # -> 'Microsoft Excel 9.0 Object Library'

Returns OLE type of WIN32OLE_PARAM object(parameter of OLE method).

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
param1 = method.params[0]
puts param1.ole_type # => VARIANT

Returns value specified by the member name of VT_RECORD OLE variable. Or sets value specified by the member name of VT_RECORD OLE variable. If the member name is not correct, KeyError exception is raised.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
End Class

Then getting/setting value from Ruby is as the following:

obj = WIN32OLE.new('ComServer.ComClass')
book = WIN32OLE_RECORD.new('Book', obj)
book.title # => nil ( book.method_missing(:title) is invoked. )
book.title = "Ruby" # ( book.method_missing(:title=, "Ruby") is invoked. )

Returns array of WIN32OLE_TYPE objects defined by the typelib type library. This method will be OBSOLETE. Use WIN32OLE_TYPELIB.new(typelib).ole_classes instead.

returns type of OLE class.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application')
puts tobj.ole_type  # => Class

Returns the WIN32OLE_TYPELIB object which is including the WIN32OLE_TYPE object. If it is not found, then returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
puts tobj.ole_typelib # => 'Microsoft Excel 9.0 Object Library'

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns OLE type string.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.ole_type} #{variable.name}"
end

The result of above script is following:
  INT xlChart
  INT xlDialogSheet
  INT xlExcel4IntlMacroSheet
  INT xlExcel4MacroSheet
  INT xlWorksheet

Returns variable kind string.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.name} #{variable.variable_kind}"
end

The result of above script is following:
  xlChart CONSTANT
  xlDialogSheet CONSTANT
  xlExcel4IntlMacroSheet CONSTANT
  xlExcel4MacroSheet CONSTANT
  xlWorksheet CONSTANT

Invoked by Ruby when obj is sent a message it cannot handle. symbol is the symbol for the method called, and args are any arguments that were passed to it. By default, the interpreter raises an error when this method is called. However, it is possible to override the method to provide more dynamic behavior. If it is decided that a particular method should not be handled, then super should be called, so that ancestors can pick up the missing method. The example below creates a class Roman, which responds to methods with names consisting of roman numerals, returning the corresponding integer values.

class Roman
  def roman_to_int(str)
    # ...
  end
  def method_missing(methId)
    str = methId.id2name
    roman_to_int(str)
  end
end

r = Roman.new
r.iv      #=> 4
r.xxiii   #=> 23
r.mm      #=> 2000

If Hash::new was invoked with a block, return that block, otherwise return nil.

h = Hash.new {|h,k| h[k] = k*k }   #=> {}
p = h.default_proc                 #=> #<Proc:0x401b3d08@-:1>
a = []                             #=> []
p.call(a, 2)
a                                  #=> [nil, nil, 4]

Sets the default proc to be executed on each failed key lookup.

h.default_proc = proc do |hash, key|
  hash[key] = key + key
end
h[2]       #=> 4
h["cat"]   #=> "catcat"

Deletes every key-value pair from hsh for which block evaluates to true.

If no block is given, an enumerator is returned instead.

h = { "a" => 100, "b" => 200, "c" => 300 }
h.delete_if {|key, value| key >= "b" }   #=> {"a"=>100}

Deletes every environment variable for which the block evaluates to true.

If no block is given an enumerator is returned instead.

Iterates over each codepoint of each file in ARGF.

This method allows you to treat the files supplied on the command line as a single file consisting of the concatenation of each named file. After the last codepoint of the first file has been returned, the first codepoint of the second file is returned. The ARGF.filename method can be used to determine the name of the file in which the current codepoint appears.

If no block is given, an enumerator is returned instead.

Synonym for ENV.

Handles the magic of delegation through _getobj_.

Returns the methods available to this delegate object as the union of this object’s and _getobj_ public methods.
