Results for: "partition"

Returns the calendar week based year.

Date.new(2001,2,3).cwyear         #=> 2001
Date.new(2000,1,1).cwyear         #=> 1999

Returns true if the date is Monday.

This method is equivalent to new_start(Date::ITALY).

Returns the second (0-59).

DateTime.new(2001,2,3,4,5,6).sec          #=> 6

Returns the timezone.

DateTime.parse('04pm+0730').zone          #=> "+07:30"

Returns the month of the year (1..12) for time.

t = Time.now   #=> 2007-11-19 08:27:30 -0600
t.mon          #=> 11
t.month        #=> 11

Returns the month of the year (1..12) for time.

t = Time.now   #=> 2007-11-19 08:27:30 -0600
t.mon          #=> 11
t.month        #=> 11

Returns the year for time (including the century).

t = Time.now   #=> 2007-11-19 08:27:51 -0600
t.year         #=> 2007

Returns the name of the time zone used for time. As of Ruby 1.8, returns “UTC” rather than “GMT” for UTC times.

t = Time.gm(2000, "jan", 1, 20, 15, 1)
t.zone   #=> "UTC"
t = Time.local(2000, "jan", 1, 20, 15, 1)
t.zone   #=> "CST"

Returns true if time represents Monday.

t = Time.local(2003, 8, 4)       #=> 2003-08-04 00:00:00 -0500
t.monday?                        #=> true

Deletes all data from the database.

Returns a Hash (not a DBM database) created by using each value in the database as a key, with the corresponding key as its value.

Returns the values for this struct as an Array.

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.to_a[1]   #=> "123 Maple, Anytown NC"

Flushes input and output buffers in kernel.

You must require ‘io/console’ to use this method.

Reads and returns a line without echo back. Prints prompt unless it is nil.

You must require ‘io/console’ to use this method.

Returns an File instance opened console.

If sym is given, it will be sent to the opened console with args and the result will be returned instead of the console IO itself.

You must require ‘io/console’ to use this method.

Returns true if an IO object is in non-blocking mode.

Enables non-blocking mode on a stream when set to true, and blocking mode when set to false.

Yields self in non-blocking mode.

When false is given as an argument, self is yielded in blocking mode. The original mode is restored after the block is executed.

Waits until IO is readable or writable without blocking and returns self, or nil when times out. Returns true immediately when buffered data is available. Optional parameter mode is one of :read, :write, or :read_write.

Opens the file, optionally seeks to the given offset, writes string, then returns the length written. write ensures the file is closed before returning. If offset is not given in write mode, the file is truncated. Otherwise, it is not truncated.

IO.write("testfile", "0123456789", 20)  #=> 10
# File could contain:  "This is line one\nThi0123456789two\nThis is line three\nAnd so on...\n"
IO.write("testfile", "0123456789")      #=> 10
# File would now read: "0123456789"

If the last argument is a hash, it specifies options for the internal open(). It accepts the following keys:

:encoding

string or encoding

Specifies the encoding of the read string. See Encoding.aliases for possible encodings.

:mode

string or integer

Specifies the mode argument for open(). It must start with “w”, “a”, or “r+”, otherwise it will cause an error. See IO.new for the list of possible modes.

:perm

integer

Specifies the perm argument for open().

:open_args

array

Specifies arguments for open() as an array. This key can not be used in combination with other keys.

Same as IO.write except opening the file in binary mode and ASCII-8BIT encoding ("wb:ASCII-8BIT").

This is a deprecated alias for each_char.

Writes the given string to ios using a low-level write. Returns the number of bytes written. Do not mix with other methods that write to ios or you may get unpredictable results. Raises SystemCallError on error.

f = File.new("out", "w")
f.syswrite("ABCDEF")   #=> 6
