Waits until IO is writable without blocking and returns self or nil when times out.
Returns the Encoding object that represents the encoding of the file. If io is in write mode and no encoding is specified, returns nil.
Returns the Encoding of the internal string if conversion is specified. Otherwise returns nil.
Returns an array of the values associated with each specified key.
Executes block for each key in the database, passing the corresponding value as a parameter.
Returns true if the given value v exists within the database. Returns false otherwise.
Provides marshalling support for use by the Marshal library.
Provides marshalling support for use by the Marshal library.
Returns true if this class can be used to create an instance from a serialised JSON string. The class has to implement a class method json_create that expects a hash as first parameter. The hash should include the required data.
Returns an Array of values corresponding to the given keys.
Iterates over each value in the database.
If no block is given, returns an Enumerator.
Returns true if the database contains the given value.
Returns an Addrinfo object for local address obtained by getsockname.
Note that addrinfo.protocol is filled by 0.
TCPSocket.open("www.ruby-lang.org", 80) {|s| p s.local_address #=> #<Addrinfo: 192.168.0.129:36873 TCP> } TCPServer.open("127.0.0.1", 1512) {|serv| p serv.local_address #=> #<Addrinfo: 127.0.0.1:1512 TCP> }
creates an Addrinfo object from the arguments.
The arguments are interpreted as similar to self.
Addrinfo.tcp("0.0.0.0", 4649).family_addrinfo("www.ruby-lang.org", 80) #=> #<Addrinfo: 221.186.184.68:80 TCP (www.ruby-lang.org:80)> Addrinfo.unix("/tmp/sock").family_addrinfo("/tmp/sock2") #=> #<Addrinfo: /tmp/sock2 SOCK_STREAM>
creates a new Socket connected to the address of local_addrinfo.
If local_addrinfo is nil, the address of the socket is not bound.
The timeout specify the seconds for timeout. Errno::ETIMEDOUT is raised when timeout occur.
If a block is given the created socket is yielded for each address.
Returns true for IPv6 link local address (ff80::/10). It returns false otherwise.
Returns true for IPv6 site local address (ffc0::/10). It returns false otherwise.
Returns the Encoding object that represents the encoding of the file. If strio is write mode and no encoding is specified, returns nil.
Returns the Encoding of the internal string if conversion is specified. Otherwise returns nil.
Duplicates a StringScanner object.
Tests whether the given pattern is matched from the current scan pointer. Advances the scan pointer if advance_pointer_p is true. Returns the matched string if return_string_p is true. The match register is affected.
“full” means “#scan with full parameters”.
