Adds file name with permissions mode, and yields an IO for writing the file to
Returns true if this gem is installable for the current platform.
Returns true if this gem is installable for the current platform.
Returns true if this specification is installable on this platform.
Iterates the given block for each element with an index, which starts from offset. If no block is given, returns a new Enumerator that includes the index, starting from offset
offset
the starting index to use
Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x returned by block is decomposed if either of the following conditions is true:
x responds to both each and force, which means that x is a lazy enumerator.
x is an array or responds to to_ary.
Otherwise, x is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]
Like Enumerable#select, but chains operation to be lazy-evaluated.
Like Enumerable#filter_map, but chains operation to be lazy-evaluated.
(1..).lazy.filter_map { |i| i * 2 if i.even? }.first(5) #=> [4, 8, 12, 16, 20]
Sets the length of the authentication tag to be generated or to be given for AEAD ciphers that requires it as in input parameter. Note that not all AEAD ciphers support this method.
In OCB mode, the length must be supplied both when encrypting and when decrypting, and must be before specifying an IV.
Sets the length of the plaintext / ciphertext message that will be processed in CCM mode. Make sure to call this method after key= and iv= have been set, and before auth_data=.
Only call this method after calling Cipher#encrypt or Cipher#decrypt.
Returns detail information of type of argument.
tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'IWorksheetFunction') method = WIN32OLE::Method.new(tobj, 'SumIf') param1 = method.params[0] p param1.ole_type_detail # => ["PTR", "USERDEFINED", "Range"]
Returns the array of WIN32OLE::Type object which is implemented by the WIN32OLE::Type object and having IMPLTYPEFLAG_FSOURCE.
tobj = WIN32OLE::Type.new('Microsoft Internet Controls', "InternetExplorer") p tobj.source_ole_types # => [#<WIN32OLE::Type:DWebBrowserEvents2>, #<WIN32OLE::Type:DWebBrowserEvents>]
Returns the array of WIN32OLE::Type object which is implemented by the WIN32OLE::Type object and having IMPLTYPEFLAG_FSOURCE and IMPLTYPEFLAG_FDEFAULT.
tobj = WIN32OLE::Type.new('Microsoft Internet Controls', "InternetExplorer") p tobj.default_event_sources # => [#<WIN32OLE::Type:DWebBrowserEvents2>]
Returns detail information of type. The information is array of type.
tobj = WIN32OLE::Type.new('DirectX 7 for Visual Basic Type Library', 'D3DCLIPSTATUS') variable = tobj.variables.find {|variable| variable.name == 'lFlags'} tdetail = variable.ole_type_detail p tdetail # => ["USERDEFINED", "CONST_D3DCLIPSTATUSFLAGS"]
Returns integer 80, the default port to use for HTTP requests:
Net::HTTP.http_default_port # => 80
Returns integer 443, the default port to use for HTTPS requests:
Net::HTTP.https_default_port # => 443
Returns whether the request may have a body:
Net::HTTP::Post.new(uri).request_body_permitted? # => true Net::HTTP::Get.new(uri).request_body_permitted? # => false
