Syslog::Logger::new

Fills in variables for Logger compatibility. If this is the first instance of Syslog::Logger, program_name may be set to change the logged program name. The facility may be set to specify the facility level which will be used.

Due to the way syslog works, only one program name may be chosen.

Syslog::Logger#add

Almost duplicates Logger#add. progname is ignored.

Integer

An Integer object represents an integer value.

You can create an Integer object explicitly with:

An integer literal.

You can convert certain objects to Integers with:

Method Integer.

An attempt to add a singleton method to an instance of this class causes an exception to be raised.

What’s Here

First, what’s elsewhere. Class Integer:

Inherits from class Numeric.

Here, class Integer provides methods for:

Querying

allbits?: Returns whether all bits in self are set.
anybits?: Returns whether any bits in self are set.
nobits?: Returns whether no bits in self are set.

Comparing

<: Returns whether self is less than the given value.
<=: Returns whether self is less than or equal to the given value.
<=>: Returns a number indicating whether self is less than, equal to, or greater than the given value.
== (aliased as ===): Returns whether self is equal to the given
```
value.
```
>: Returns whether self is greater than the given value.
>=: Returns whether self is greater than or equal to the given value.

Converting

::sqrt: Returns the integer square root of the given value.
::try_convert: Returns the given value converted to an Integer.
% (aliased as modulo): Returns self modulo the given value.
&: Returns the bitwise AND of self and the given value.
*: Returns the product of self and the given value.
**: Returns the value of self raised to the power of the given value.
+: Returns the sum of self and the given value.
-: Returns the difference of self and the given value.
/: Returns the quotient of self and the given value.
<<: Returns the value of self after a leftward bit-shift.
>>: Returns the value of self after a rightward bit-shift.
[]: Returns a slice of bits from self.
^: Returns the bitwise EXCLUSIVE OR of self and the given value.
ceil: Returns the smallest number greater than or equal to self.
chr: Returns a 1-character string containing the character represented by the value of self.
digits: Returns an array of integers representing the base-radix digits of self.
div: Returns the integer result of dividing self by the given value.
divmod: Returns a 2-element array containing the quotient and remainder results of dividing self by the given value.
fdiv: Returns the Float result of dividing self by the given value.
floor: Returns the greatest number smaller than or equal to self.
pow: Returns the modular exponentiation of self.
pred: Returns the integer predecessor of self.
remainder: Returns the remainder after dividing self by the given value.
round: Returns self rounded to the nearest value with the given precision.
succ (aliased as next): Returns the integer successor of self.
to_f: Returns self converted to a Float.
to_s (aliased as inspect): Returns a string containing the place-value representation of self in the given radix.
truncate: Returns self truncated to the given precision.
|: Returns the bitwise OR of self and the given value.

Other

downto: Calls the given block with each integer value from self down to the given value.
times: Calls the given block self times with each integer in (0..self-1).
upto: Calls the given block with each integer value from self up to the given value.

FiberError

Raised when an invalid operation is attempted on a Fiber, in particular when attempting to call/resume a dead fiber, attempting to yield from the root fiber, or calling a fiber across threads.

fiber = Fiber.new{}
fiber.resume #=> nil
fiber.resume #=> FiberError: dead fiber called

RangeError

Raised when a given numerical value is out of range.

[1, 2, 3].drop(1 << 100)

raises the exception:

RangeError: bignum too big to convert into `long'

LoadError

Raised when a file required (a Ruby script, extension library, …) fails to load.

require 'this/file/does/not/exist'

raises the exception:

LoadError: no such file to load -- this/file/does/not/exist
