Returns true if this specification is installable on this platform.
@return [Object] most up-to-date dependency in the possibility set
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"]
Set the default value for the :argc_limit option.
See new(). The initial default value is 256.
Set the default value for the :load_limit option.
See new(). The initial default value is 25 MB.
Check that a method is callable via dRuby.
obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.
If the method is an insecure method (see insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.
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
