returns an addrinfo object for UNIX socket address.
socktype specifies the socket type. If it is omitted, :STREAM is used.
Addrinfo.unix("/tmp/sock") #=> #<Addrinfo: /tmp/sock SOCK_STREAM> Addrinfo.unix("/tmp/sock", :DGRAM) #=> #<Addrinfo: /tmp/sock SOCK_DGRAM>
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 true if addrinfo is UNIX address. returns false otherwise.
Addrinfo.tcp("127.0.0.1", 80).unix? #=> false Addrinfo.tcp("::1", 80).unix? #=> false Addrinfo.unix("/tmp/sock").unix? #=> true
Returns 0. Just for compatibility to IO.
Returns true always.
Returns the argument unchanged. Just for compatibility to IO.
Pushes back one character (passed as a parameter) onto strio such that a subsequent buffered read will return it. There is no limitation for multiple pushbacks including pushing back behind the beginning of the buffer string.
Set the scan pointer to the previous position. Only one previous position is remembered, and it changes with each scanning operation.
s = StringScanner.new('test string') s.scan(/\w+/) # => "test" s.unscan s.scan(/../) # => "te" s.scan(/\d/) # => nil s.unscan # ScanError: unscan failed: previous match record not exist
Returns a string that represents the StringScanner object, showing:
the current position
the size of the string
the characters surrounding the scan pointer
s = StringScanner.new(“Fri Dec 12 1975 14:39”) s.inspect # -> ‘#<StringScanner 0/21 @ “Fri D…”>’ s.scan_until /12/ # -> “Fri Dec 12” s.inspect # -> ‘#<StringScanner 10/21 “…ec 12” @ “ 1975…”>’
disconnects OLE server. If this method called, then the WIN32OLE_EVENT object does not receive the OLE server event any more. This method is trial implementation.
ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event() {...}
...
ev.unadvise
Returns help context.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks') method = WIN32OLE_METHOD.new(tobj, 'Add') puts method.helpcontext # => 65717
Returns the method name with class name.
Returns the parameter name with class name. If the parameter has default value, then returns name=value string with class name.
Returns the OLE struct name and member name and the value of member
If COM server in VB.NET ComServer project is the following:
Imports System.Runtime.InteropServices
Public Class ComClass
<MarshalAs(UnmanagedType.BStr)> _
Public title As String
Public cost As Integer
End Class
then
srver = WIN32OLE.new('ComServer.ComClass') obj = WIN32OLE_RECORD.new('Book', server) obj.inspect # => <WIN32OLE_RECORD(ComClass) {"title" => nil, "cost" => nil}>
Returns helpcontext. If helpcontext is not found, then returns nil.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet') puts tobj.helpfile # => 131185
Returns the type name with class name.
ie = WIN32OLE.new('InternetExplorer.Application')
ie.ole_type.inspect => #<WIN32OLE_TYPE:IWebBrowser2>
Returns the type library name with class name.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') tlib.inspect # => "<#WIN32OLE_TYPELIB:Microsoft Excel 9.0 Object Library>"
Returns the OLE variable name and the value with class name.
Return the contents of this hash as a string.
h = { "c" => 300, "a" => 100, "d" => 400, "c" => 300 } h.to_s #=> "{\"c\"=>300, \"a\"=>100, \"d\"=>400}"
Returns a new hash consisting of entries for which the block returns false.
If no block is given, an enumerator is returned instead.
h = { "a" => 100, "b" => 200, "c" => 300 } h.reject {|k,v| k < "b"} #=> {"b" => 200, "c" => 300} h.reject {|k,v| v > 100} #=> {"a" => 100}
Equivalent to Hash#delete_if, but returns nil if no changes were made.
Returns a new hash with the nil values/key pairs removed
h = { a: 1, b: false, c: nil } h.compact #=> { a: 1, b: false } h #=> { a: 1, b: false, c: nil }
Removes all nil values from the hash. Returns nil if no changes were made, otherwise returns the hash.
h = { a: 1, b: false, c: nil } h.compact! #=> { a: 1, b: false }
Returns true if the given key is present in hsh.
h = { "a" => 100, "b" => 200 } h.has_key?("a") #=> true h.has_key?("z") #=> false
Note that include? and member? do not test member equality using == as do other Enumerables.
