Stores value in database with key as the index. value is converted to YAML before being stored.
Returns value
Returns a string representation of self:
system("false") $?.inspect # => "#<Process::Status: pid 1303494 exit 1>"
Returns true if this process is stopped, and if the corresponding wait call had the Process::WUNTRACED flag set, false otherwise.
Returns the number of the signal that caused the process to stop, or nil if the process is not stopped.
Returns the least significant eight bits of the return code of the process if it has exited; nil otherwise:
`exit 99` $?.exitstatus # => 99
Wakes up all threads waiting for this lock.
Returns the length of the queue.
Returns the length of the queue.
Returns a printable version of ec
ec = Encoding::Converter.new("iso-8859-1", "utf-8") puts ec.inspect #=> #<Encoding::Converter: ISO-8859-1 to UTF-8>
Finishes the converter. It returns the last part of the converted string.
ec = Encoding::Converter.new("utf-8", "iso-2022-jp") p ec.convert("\u3042") #=> "\e$B$\"" p ec.finish #=> "\e(B"
Returns true if key is a key in self, otherwise false.
Returns the number of referenced objects
Returns a new String containing informations about the map:
m = ObjectSpace::WeakKeyMap.new m[key] = value m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"
Returns URL-escaped string following RFC 3986.
Returns URL-unescaped string following RFC 3986.
URL-encode a string following RFC 3986 Space characters (+“ ”+) are encoded with (+“%20”+)
url_encoded_string = CGI.escapeURIComponent("'Stop!' said Fred") # => "%27Stop%21%27%20said%20Fred"
URL-decode a string following RFC 3986 with encoding(optional).
string = CGI.unescapeURIComponent("%27Stop%21%27+said%20Fred") # => "'Stop!'+said Fred"
Finishes the digest and returns the resulting hash value.
This method is overridden by each implementation subclass and often made private, because some of those subclasses may leave internal data uninitialized. Do not call this method from outside. Use digest!() instead, which ensures that internal data be reset for security reasons.
Creates a printable version of the digest object.
If none is given, returns the resulting hash value of the digest, keeping the digest’s state.
If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.
Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
Returns digest_obj.digest_length().
