/**
 * @assertion int hashCode
 * 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.
