Deserializes JSON string by converting Julian year y, month m, day d and Day of Calendar Reform sg to Date.
Returns a Time object which denotes self.
Returns a Date object which denotes self.
Deserializes JSON string by converting year y, month m, day d, hour H, minute M, second S, offset of and Day of Calendar Reform sg to DateTime.
Returns self.
Returns a Date object which denotes self.
Returns an array containing the values associated with the given keys.
Calls the block once for each [key, value] pair in the database. Returns self.
Yields the name and value of each struct member in order. If no block is given an enumerator is returned.
Customer = Struct.new(:name, :address, :zip) joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345) joe.each_pair {|name, value| puts("#{name} => #{value}") }
Produces:
name => Joe Smith address => 123 Maple, Anytown NC zip => 12345
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]
IO.copy_stream copies src to dst. src and dst is either a filename or an IO-like object. IO-like object for src should have readpartial or read method. IO-like object for dst should have write method. (Specialized mechanisms, such as sendfile system call, may be used on appropriate situation.)
This method returns the number of bytes copied.
If optional arguments are not given, the start position of the copy is the beginning of the filename or the current file offset of the IO. The end position of the copy is the end of file.
If copy_length is given, No more than copy_length bytes are copied.
If src_offset is given, it specifies the start position of the copy.
When src_offset is specified and src is an IO, IO.copy_stream doesn’t move the current file offset.
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 key and the corresponding value as a parameter.
Yields all attributes (as symbols) along with the corresponding values or returns an enumerator if no block is given.
require "ostruct" data = OpenStruct.new("country" => "Australia", :capital => "Canberra") data.each_pair.to_a # => [[:country, "Australia"], [:capital, "Canberra"]]
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"
