/// The hash code for this object.
/// A hash code is a single integer which represents the state of the object that
/// affects == comparisons.
/// All objects have hash codes. The default hash code represents only the
/// identity of the object, the same way as the default == implementation only
/// considers objects equal if they are identical (see identityHashCode).
/// @description Checks that equals objects have equal hash codes and different
/// objects have different hash codes.
