Returns the struct member values for each selector as an Array. A selector may be either an Integer offset or a Range of offsets (as in Array#values_at).

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.values_at(0, 2)   #=> ["Joe Smith", 12345]

Waits until IO is readable without blocking and returns self, or nil when times out. Returns true immediately when buffered data is available.

Waits until IO is writable without blocking and returns self or nil when times out.

Returns an array of the values associated with each specified key.

Deserializes JSON string by constructing new Struct object with values t serialized by to_json.

Deserializes JSON string by constructing new Range object with arguments a serialized by to_json.

Deserializes JSON string by constructing new Regexp object with source s (Regexp or String) and options o serialized by to_json

The first form returns the MatchData object generated by the last successful pattern match. Equivalent to reading the special global variable $~ (see Special global variables in Regexp for details).

The second form returns the nth field in this MatchData object. n can be a string or symbol to reference a named capture.

Note that the last_match is local to the thread and method scope of the method that did the pattern match.

/c(.)t/ =~ 'cat'        #=> 0
Regexp.last_match       #=> #<MatchData "cat" 1:"a">
Regexp.last_match(0)    #=> "cat"
Regexp.last_match(1)    #=> "a"
Regexp.last_match(2)    #=> nil

/(?<lhs>\w+)\s*=\s*(?<rhs>\w+)/ =~ "var = val"
Regexp.last_match       #=> #<MatchData "var = val" lhs:"var" rhs:"val">
Regexp.last_match(:lhs) #=> "var"
Regexp.last_match(:rhs) #=> "val"

Deserializes JSON string by converting the string value stored in the object to a Symbol

Return the path as a String.

to_path is implemented so Pathname objects are usable with File.open, etc.

Returns the absolute path for the file.

Returns an Array of values corresponding to the given keys.

Returns true for IPv4 private address (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). It returns false otherwise.

Returns true for IPv4-compatible IPv6 address (::/80). It returns false otherwise.

Returns the socket path as a string.

Addrinfo.unix("/tmp/sock").unix_path       #=> "/tmp/sock"

Returns the size of the most recent match (see matched), or nil if there was no recent match.

s = StringScanner.new('test string')
s.check /\w+/           # -> "test"
s.matched_size          # -> 4
s.check /\d+/           # -> nil
s.matched_size          # -> nil

Return the pre-match

s = StringScanner.new('test string')
s.scan(/\w+/)           # -> "test"
s.scan(/\s+/)           # -> " "
s.pre_match             # -> "test"
s.post_match            # -> "string"

Return the post-match

s = StringScanner.new('test string')
s.scan(/\w+/)           # -> "test"
s.scan(/\s+/)           # -> " "
s.pre_match             # -> "test"
s.post_match            # -> "string"
