@param [Vertex] other the other vertex to compare to @return [Boolean] whether the two vertices are equal, determined
solely by {#name} and {#payload} equality
Get all [gem, version] from the command line.
An argument in the form gem:ver is pull apart into the gen name and version, respectively.
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#take_while
, but chains operation to be lazy-evaluated.
Like Enumerable#map
, but chains operation to be lazy-evaluated.
(1..Float::INFINITY).lazy.map {|i| i**2 } #=> #<Enumerator::Lazy: #<Enumerator::Lazy: 1..Infinity>:map> (1..Float::INFINITY).lazy.map {|i| i**2 }.first(3) #=> [1, 4, 9]

Cast this pointer to a ruby object.
Sets the cipher’s additional authenticated data. This field must be set when using AEAD cipher modes such as GCM or CCM. If no associated data shall be used, this method must still be called with a value of “”. The contents of this field should be non-sensitive data which will be added to the ciphertext to generate the authentication tag which validates the contents of the ciphertext.
The AAD must be set prior to encryption or decryption. In encryption mode, it must be set after calling Cipher#encrypt
and setting Cipher#key=
and Cipher#iv=
. When decrypting, the authenticated data must be set after key, iv and especially after the authentication tag has been set. I.e. set it only after calling Cipher#decrypt
, Cipher#key=
, Cipher#iv=
and Cipher#auth_tag=
first.
Sets the authentication tag to verify the integrity of the ciphertext. This can be called only when the cipher supports AE. The tag must be set after calling Cipher#decrypt
, Cipher#key=
and Cipher#iv=
, but before calling Cipher#final
. After all decryption is performed, the tag is verified automatically in the call to Cipher#final
.
For OCB mode, the tag length must be supplied with auth_tag_len=
beforehand.
Gets the authentication tag generated by Authenticated Encryption Cipher
modes (GCM for example). This tag may be stored along with the ciphertext, then set on the decryption cipher to authenticate the contents of the ciphertext against changes. If the optional integer parameter tag_len is given, the returned tag will be tag_len bytes long. If the parameter is omitted, the default length of 16 bytes or the length previously set by auth_tag_len=
will be used. For maximum security, the longest possible should be chosen.
The tag may only be retrieved after calling Cipher#final
.
Gets the value of key from the given section
Given the following configurating file being loaded:
config = OpenSSL::Config.load('foo.cnf') #=> #<OpenSSL::Config sections=["default"]> puts config.to_s #=> [ default ] # foo=bar
You can get a specific value from the config if you know the section and key like so:
config.get_value('default','foo') #=> "bar"
*Deprecated in v2.2.0*. This method will be removed in a future release.
Set
the target key with a given value under a specific section.
Given the following configurating file being loaded:
config = OpenSSL::Config.load('foo.cnf') #=> #<OpenSSL::Config sections=["default"]> puts config.to_s #=> [ default ] # foo=bar
You can set the value of foo under the default section to a new value:
config.add_value('default', 'foo', 'buzz') #=> "buzz" puts config.to_s #=> [ default ] # foo=buzz
Emit a scalar with value
