Results for: "pstore"

Use Addrinfo.getaddrinfo instead. This method is deprecated for the following reasons:

• The 3rd element of the result is the address family of the first address. The address families of the rest of the addresses are not returned.

• gethostbyname() may take a long time and it may block other threads. (GVL cannot be released since gethostbyname() is not thread safe.)

• This method uses gethostbyname() function already removed from POSIX.

This method lookups host information by hostname.

TCPSocket.gethostbyname("localhost")
#=> ["localhost", ["hal"], 2, "127.0.0.1"]

Receives a message via unixsocket.

maxlen is the maximum number of bytes to receive.

flags should be a bitwise OR of Socket::MSG_* constants.

outbuf will contain only the received data after the method call even if it is not empty at the beginning.

s1 = Socket.new(:UNIX, :DGRAM, 0)
s1_ai = Addrinfo.unix("/tmp/sock1")
s1.bind(s1_ai)

s2 = Socket.new(:UNIX, :DGRAM, 0)
s2_ai = Addrinfo.unix("/tmp/sock2")
s2.bind(s2_ai)
s3 = UNIXSocket.for_fd(s2.fileno)

s1.send "a", 0, s2_ai
p s3.recvfrom(10) #=> ["a", ["AF_UNIX", "/tmp/sock1"]]

Reinitializes strio with the given other_StrIO or string and mode (see StringIO#new).

Returns underlying String object, the subject of IO.

Changes underlying String object, the subject of IO.

Positions strio to the beginning of input, resetting lineno to zero.

See IO#readlines.

See IO#read.

Reset the scan pointer (index 0) and clear matching data.

Returns the string being scanned.

Changes the string being scanned to str and resets the scanner. Returns str.

Looks ahead to see if the pattern exists anywhere in the string, without advancing the scan pointer. This predicates whether a scan_until will return a value.

s = StringScanner.new('test string')
s.exist? /s/            # -> 3
s.scan /test/           # -> "test"
s.exist? /s/            # -> 2
s.exist? /e/            # -> nil

Returns the subgroups in the most recent match (not including the full match). If nothing was priorly matched, it returns nil.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.scan(/(\w+) (\w+) (\d+) /)       # -> "Fri Dec 12 "
s.captures                         # -> ["Fri", "Dec", "12"]
s.scan(/(\w+) (\w+) (\d+) /)       # -> nil
s.captures                         # -> nil

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 true if argument is return value.

tobj = WIN32OLE_TYPE.new('DirectX 7 for Visual Basic Type Library',
                         'DirectPlayLobbyConnection')
method = WIN32OLE_METHOD.new(tobj, 'GetPlayerShortName')
param = method.params[0]
puts "#{param.name} #{param.retval?}"  # => name true

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 Ruby Hash object which represents VT_RECORD variable. The keys of Hash object are member names of VT_RECORD OLE variable and the values of Hash object are values 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#to_h is the following:

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book = obj.getBook
book.to_h # => {"title"=>"The Ruby Book", "cost"=>20}

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 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

Rebuilds the hash based on the current hash values for each key. If values of key objects have changed since they were inserted, this method will reindex hsh. If Hash#rehash is called while an iterator is traversing the hash, a RuntimeError will be raised in the iterator.

a = [ "a", "b" ]
c = [ "c", "d" ]
h = { a => 100, c => 300 }
h[a]       #=> 100
a[0] = "z"
h[a]       #=> nil
h.rehash   #=> {["z", "b"]=>100, ["c", "d"]=>300}
h[a]       #=> 100

Returns self. If called on a subclass of Hash, converts the receiver to a Hash object.

Converts hsh to a nested array of [ key, value ] arrays.

h = { "c" => 300, "a" => 100, "d" => 400, "c" => 300  }
h.to_a   #=> [["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.
