Instance Method Detail
Description copied from module Comparable(Spot)
The comparison operator. Returns 0
if the two objects are equal,
a negative number if this object is considered less than other,
a positive number if this object is considered greater than other,
or nil
if the two objects are not comparable.
Subclasses define this method to provide class-specific ordering.
The comparison operator is usually used to sort values:
# Sort in a descending way:
[3, 1, 2].sort { |x, y| y <=> x } # => [3, 2, 1]
# Sort in an ascending way:
[3, 1, 2].sort { |x, y| x <=> y } # => [1, 2, 3]
