Results for: "Logger"

Equivalent to calling add with severity Logger::INFO.

Equivalent to calling add with severity Logger::WARN.

Equivalent to calling add with severity Logger::FATAL.

Equivalent to calling add with severity Logger::UNKNOWN.

Guarantee the existence of this ivar even when subclasses don’t call the superclass constructor.

Adjust the log level during the block execution for the current Fiber only

logger.with_level(:debug) do
  logger.debug { "Hello" }
end

Sets the date-time format.

Argument datetime_format should be either of these:

• A string suitable for use as a format for method Time#strftime.

• nil: the logger uses '%Y-%m-%dT%H:%M:%S.%6N'.

Returns the date-time format; see datetime_format=.

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 and class Object.

• Includes module Comparable.

Here, class Integer provides methods for:

• Querying

• Comparing

• Converting

• Other

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.

• |: Returns the bitwise 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.

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.
