Results for: "tally"

Waits until IO is writable and returns true or false 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.

Dup internal hash.

Clone internal hash.

Returns true if sym starts with one of the prefixes given. Each of the prefixes should be a String or a Regexp.

:hello.start_with?("hell")               #=> true
:hello.start_with?(/H/i)                 #=> true

# returns true if one of the prefixes matches.
:hello.start_with?("heaven", "hell")     #=> true
:hello.start_with?("heaven", "paradise") #=> false

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 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 the stream 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”.

Scans the string until the pattern is matched. Advances the scan pointer if advance_pointer_p, otherwise not. Returns the matched string if return_string_p is true, otherwise returns the number of bytes advanced. This method does affect the match register.

Returns the subgroups in the most recent match at the given indices. If nothing was priorly matched, it returns nil.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.scan(/(\w+) (\w+) (\d+) /)       # -> "Fri Dec 12 "
s.values_at 0, -1, 5, 2            # -> ["Fri Dec 12 ", "12", nil, "Dec"]
s.scan(/(\w+) (\w+) (\d+) /)       # -> nil
s.values_at 0, -1, 5, 2            # -> nil
