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]
Creates a State object from opts, which ought to be Hash to create a new State instance configured by opts, something else to create an unconfigured instance. If opts is a State object, it is just returned.
This integer returns the maximum level of data structure nesting in the generated JSON, max_nesting = 0 if no maximum is checked.
This sets the maximum level of data structure nesting in the generated JSON to the integer depth, max_nesting = 0 if no maximum should be checked.
Returns true, if circular data structures should be checked, otherwise returns false.
Generates a valid JSON document from object obj and returns the result. If no valid JSON document can be created this method raises a GeneratorError exception.
This method is deprecated and should not be used. This is a no-op.
Sets the curve parameters. generator must be an instance of EC::Point that is on the curve. order and cofactor are integers.
See the OpenSSL documentation for EC_GROUP_set_generator()
Negate the value of a numeric node. This is a special case where you have a negative sign on one line and then a number on the next line. In normal Ruby, this will always be a method call. The parser gem, however, marks this as a numeric literal. We have to massage the tree here to get it into the correct form.
The parser gem automatically converts rn to n, meaning our offsets need to be adjusted to always subtract 1 from the length.
Within the given block, track that we’re within a pattern.
Parse a float from the string representation.
Parse a rational from the string representation.
The current session cache mode.
Sets the SSL session cache mode. Bitwise-or together the desired SESSION_CACHE_* constants to set. See SSL_CTX_set_session_cache_mode(3) for details.
Returns the current session cache size. Zero is used to represent an unlimited cache size.
Sets the session cache size. Returns the previously valid session cache size. Zero is used to represent an unlimited session cache size.
Perform hostname verification following RFC 6125.
This method MUST be called after calling connect to ensure that the hostname of a remote peer has been verified.
The X509 certificate chain for this socket’s peer.
Serializes the private key to DER-encoded PKCS #8 format. If called without arguments, unencrypted PKCS #8 PrivateKeyInfo format is used. If called with a cipher name and a password, PKCS #8 EncryptedPrivateKeyInfo format with PBES2 encryption scheme is used.
Serializes the private key to PEM-encoded PKCS #8 format. See private_to_der for more details.
An unencrypted PEM-encoded key will look like:
-----BEGIN PRIVATE KEY----- [...] -----END PRIVATE KEY-----
An encrypted PEM-encoded key will look like:
-----BEGIN ENCRYPTED PRIVATE KEY----- [...] -----END ENCRYPTED PRIVATE KEY-----
