The iterator version of the TSort.strongly_connected_components
method.
The graph is represented by each_node and each_child. each_node should have call
method which yields for each node in the graph. each_child should have call
method which takes a node argument and yields for each child node.
g = {1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]} each_node = lambda {|&b| g.each_key(&b) } each_child = lambda {|n, &b| g[n].each(&b) } TSort.each_strongly_connected_component(each_node, each_child) {|scc| p scc } #=> [4] # [2] # [3] # [1] g = {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]} each_node = lambda {|&b| g.each_key(&b) } each_child = lambda {|n, &b| g[n].each(&b) } TSort.each_strongly_connected_component(each_node, each_child) {|scc| p scc } #=> [4] # [2, 3] # [1]
Enables or disables padding. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the pad parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.
See EVP_CIPHER_CTX_set_padding for further information.
Returns an array of currently loaded engines.
Creates a new Socket::Option
object for SOL_SOCKET/SO_LINGER.
onoff should be an integer or a boolean.
secs should be the number of seconds.
p Socket::Option.linger(true, 10) #=> #<Socket::Option: UNSPEC SOCKET LINGER on 10sec>
Returns the linger data in sockopt as a pair of boolean and integer.
sockopt = Socket::Option.linger(true, 10) p sockopt.linger => [true, 10]

Symmetric Householder reduction to tridiagonal form.
Returns true
if U
, and hence A
, is singular.
Puts the connection into binary (image) mode, issues the given command, and fetches the data returned, passing it to the associated block in chunks of blocksize
characters. Note that cmd
is a server command (such as “RETR myfile”).
Puts the connection into ASCII (text) mode, issues the given command, and passes the resulting data, one line at a time, to the associated block. If no block is given, prints the lines. Note that cmd
is a server command (such as “RETR myfile”).
Puts the connection into binary (image) mode, issues the given server-side command (such as “STOR myfile”), and sends the contents of the file named file
to the server. If the optional block is given, it also passes it the data, in chunks of blocksize
characters.

Creates a singleton RingFinger
and looks for a RingServer
. Returns the created RingFinger
.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager
instance to stand in for the class itself.
Installs the gem dep_or_name
and all its dependencies. Returns an Array
of installed gem specifications.
If the :prerelease
option is set and there is a prerelease for dep_or_name
the prerelease version will be installed.
Unless explicitly specified as a prerelease dependency, prerelease gems that dep_or_name
depend on will not be installed.
If c-1.a depends on b-1 and a-1.a and there is a gem b-1.a available then c-1.a, b-1 and a-1.a will be installed. b-1.a will need to be installed separately.
Changes in rubygems to lazily loading ‘rubygems/command` (in order to lazily load `optparse` as a side effect) affect bundler’s custom installer which uses ‘Gem::Command` without requiring it (up until bundler 2.2.29). This hook is to compensate for that missing require.
TODO: Remove when rubygems no longer supports running on bundler older than 2.2.29.
