Results for: "Pathname"

Returns a new lazy enumerator with the concatenated results of running block once for every element in lazy.

["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:

a) <i>x</i> responds to both each and force, which means that
   <i>x</i> is a lazy enumerator.
b) <i>x</i> 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}]

Return the length of the hash value in bytes.

Return the block length of the digest in bytes.

Enable a call to dlclose() when this handle is garbage collected.

Returns true if dlclose() will be called when this handle is garbage collected.

See man(3) dlclose() for more info.

Performs a Miller-Rabin primality test. This is same as prime? except this first attempts trial divisions with some small primes.

Parameters

• checks - integer

• trial_div - boolean

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.

Parses the configuration data read from io, see also parse.

Raises a ConfigError on invalid configuration data.

Returns the output size of the digest, i.e. the length in bytes of the final message digest result.

Example

digest = OpenSSL::Digest::SHA1.new
puts digest.digest_length # => 20

Returns the block length of the digest algorithm, i.e. the length in bytes of an individual block. Most modern algorithms partition a message to be digested into a sequence of fix-sized blocks that are processed consecutively.

Example

digest = OpenSSL::Digest::SHA1.new
puts digest.block_length # => 64

Called with encoding when the YAML stream starts. This method is called once per stream. A stream may contain multiple documents.

See the constants in Psych::Parser for the possible values of encoding.

Called when the document starts with the declared version, tag_directives, if the document is implicit.

version will be an array of integers indicating the YAML version being dealt with, tag_directives is a list of tuples indicating the prefix and suffix of each tag, and implicit is a boolean indicating whether the document is started implicitly.

Example

Given the following YAML:

%YAML 1.1
%TAG ! tag:tenderlovemaking.com,2009:
--- !squee

The parameters for start_document must be this:

version         # => [1, 1]
tag_directives  # => [["!", "tag:tenderlovemaking.com,2009:"]]
implicit        # => false

Called with the document ends. implicit is a boolean value indicating whether or not the document has an implicit ending.

Example

Given the following YAML:

---
  hello world

implicit will be true. Given this YAML:

---
  hello world
...

implicit will be false.

Called when the YAML stream ends

Called before each event with line/column information.

Parse and return an int from string
