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 MAC parameters and generates MAC over the PKCS #12 structure.
This method uses HMAC and the PKCS #12 specific password-based KDF as specified in the original PKCS #12.
See also the man page PKCS12_set_mac(3).
Added in version 3.3.0.
Emit a sequence with map and tag
Called when a map starts.
anchor is the anchor associated with the map or nil. tag is the tag associated with the map or nil. implicit is a boolean indicating whether or not the map was implicitly started. style is an integer indicating the mapping style.
See the constants in Psych::Nodes::Mapping for the possible values of style.
Here is a YAML document that exercises most of the possible ways this method can be called:
---
k: !!map { hello: world }
v: &pewpew
hello: world
The above YAML document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:map", false, 2 ] ["pewpew", nil, true, 1 ]
Called when a map ends
Called before each event with line/column information.
Start emitting a YAML map with anchor, tag, an implicit start and end, and style.
Enumerate all values in this registry path.
For each value it yields key, type and data.
key is a String which contains name of key. type is a type contant kind of Win32::Registry::REG_* data is the value of this key.
Enumerate all subkeys.
For each subkey it yields subkey and wtime.
subkey is String which contains name of subkey. wtime is last write time as FILETIME (64-bit integer). (see Registry.wtime2time)
Guesses the type of the data which have been inputted into the stream. The returned value is either BINARY, ASCII, or UNKNOWN.
See Zlib::GzipReader documentation for a description.

Returns the major part of File_Stat#dev or nil.
File.stat("/dev/fd1").dev_major #=> 2 File.stat("/dev/tty").dev_major #=> 5
Returns the major part of File_Stat#rdev or nil.
File.stat("/dev/fd1").rdev_major #=> 2 File.stat("/dev/tty").rdev_major #=> 5
Iterates over the buffer, yielding each byte starting from offset.
If count is given, only count bytes will be yielded.
IO::Buffer.for("Hello World").each_byte(2, 2) do |offset, byte| puts "#{offset}: #{byte}" end # 2: 108 # 3: 108
Returns the absolute path of this instruction sequence.
nil if the iseq was evaluated from a string.
For example, using ::compile_file:
# /tmp/method.rb
def hello
puts "hello, world"
end
# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.absolute_path #=> /tmp/method.rb
Take a location from the prism parser and set the necessary instance variables.
Sets the maximum number of times to retry an idempotent request in case of Net::ReadTimeout, IOError, EOFError, Errno::ECONNRESET, Errno::ECONNABORTED, Errno::EPIPE, OpenSSL::SSL::SSLError, Timeout::Error. The initial value is 1.
Argument retries must be a non-negative numeric value:
http = Net::HTTP.new(hostname) http.max_retries = 2 # => 2 http.max_retries # => 2
