Returns the remote address of the socket as a sockaddr string.
TCPServer.open("127.0.0.1", 1440) {|serv| c = TCPSocket.new("127.0.0.1", 1440) s = serv.accept p s.getpeername #=> "\x02\x00\x82u\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" }
If Addrinfo object is preferred over the binary string, use BasicSocket#remote_address.
returns the canonical name as an string.
nil is returned if no canonical name.
The canonical name is set by Addrinfo.getaddrinfo when AI_CANONNAME is specified.
list = Addrinfo.getaddrinfo("www.ruby-lang.org", 80, :INET, :STREAM, nil, Socket::AI_CANONNAME) p list[0] #=> #<Addrinfo: 221.186.184.68:80 TCP carbon.ruby-lang.org (www.ruby-lang.org)> p list[0].canonname #=> "carbon.ruby-lang.org"
returns nodename and service as a pair of strings. This converts struct sockaddr in addrinfo to textual representation.
flags should be bitwise OR of Socket::NI_??? constants.
Addrinfo.tcp("127.0.0.1", 80).getnameinfo #=> ["localhost", "www"] Addrinfo.tcp("127.0.0.1", 80).getnameinfo(Socket::NI_NUMERICSERV) #=> ["localhost", "80"]
Returns the path of the local address of unixsocket.
s = UNIXServer.new("/tmp/sock") p s.path #=> "/tmp/sock"
call-seq
WIN32OLE_METHOD#name
Returns the name of the method.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') puts method.name # => SaveAs
Returns name.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') param1 = method.params[0] puts param1.name # => Filename
Returns the type name of VT_RECORD OLE variable.
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
Public Function getBook() As Book
Dim book As New Book
book.title = "The Ruby Book"
book.cost = 20
Return book
End Function
End Class
then, the result of WIN32OLE_RECORD#typename is the following:
require 'win32ole' obj = WIN32OLE.new('ComServer.ComClass') book = obj.getBook book.typename # => "Book"
Returns OLE type name.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application') puts tobj.name # => Application
Returns the type library name.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') name = tlib.name # -> 'Microsoft Excel 9.0 Object Library'
Returns the type library file path.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') puts tlib.path #-> 'C:\...\EXCEL9.OLB'
Returns the name of variable.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') variables = tobj.variables variables.each do |variable| puts "#{variable.name}" end The result of above script is following: xlChart xlDialogSheet xlExcel4IntlMacroSheet xlExcel4MacroSheet xlWorksheet
Returns the current filename. “-” is returned when the current file is STDIN.
For example:
$ echo "foo" > foo $ echo "bar" > bar $ echo "glark" > glark $ ruby argf.rb foo bar glark ARGF.filename #=> "foo" ARGF.read(5) #=> "foo\nb" ARGF.filename #=> "bar" ARGF.skip ARGF.filename #=> "glark"
Returns the current filename. “-” is returned when the current file is STDIN.
For example:
$ echo "foo" > foo $ echo "bar" > bar $ echo "glark" > glark $ ruby argf.rb foo bar glark ARGF.filename #=> "foo" ARGF.read(5) #=> "foo\nb" ARGF.filename #=> "bar" ARGF.skip ARGF.filename #=> "glark"
Returns a list of names of captures as an array of strings. It is same as mtch.regexp.names.
/(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge").names #=> ["foo", "bar", "baz"] m = /(?<x>.)(?<y>.)?/.match("a") #=> #<MatchData "a" x:"a" y:nil> m.names #=> ["x", "y"]
Returns the path to the data store file.
Looks up the hostname of address.
Looks up all hostnames for address.
Looks up the hostname of address.
Looks up all hostnames for address.
Returns the full path name of the temporary file. This will be nil if unlink has been called.
show the name of the thread.
set given name to the ruby thread. On some platform, it may set the name to pthread and/or kernel.
Returns the parameter information of this proc.
prc = lambda{|x, y=42, *other|} prc.parameters #=> [[:req, :x], [:opt, :y], [:rest, :other]]
Returns the name of the method.
Returns the parameter information of this method.
def foo(bar); end method(:foo).parameters #=> [[:req, :bar]] def foo(bar, baz, bat, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:req, :bat], [:block, :blk]] def foo(bar, *args); end method(:foo).parameters #=> [[:req, :bar], [:rest, :args]] def foo(bar, baz, *args, &blk); end method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:rest, :args], [:block, :blk]]
