#

#
# == Retrieving the instance
#
# For convenience, each instance method of +Prime+.instance can be accessed
# as a class method of +Prime+.
#
# e.g.
#   Prime.instance.prime?(2)  #=> true
#   Prime.prime?(2)           #=> true
#
# == Generators
#
# A "generator" provides an implementation of enumerating pseudo-prime
# numbers and it remembers the position of enumeration and upper bound.
# Furthermore, it is an external iterator of prime enumeration which is
# compatible with an Enumerator.
#
# +Prime+::+PseudoPrimeGenerator+ is the base class for generators.
# There are few implementations of generator.
#
# [+Prime+::+EratosthenesGenerator+]
#   Uses eratosthenes' sieve.
# [+Prime+::+TrialDivisionGenerator+]
#   Uses the trial division method.
# [+Prime+::+Generator23+]
#   Generates all positive integers which are not divisible by either 2 or 3.
#   This sequence is very bad as a pseudo-prime sequence. But this
#   is faster and uses much less memory than the other generators. So,
#   it is suitable for factorizing an integer which is not large but
#   has many prime factors. e.g. for Prime#prime? .

# Iterates the given block over all prime numbers.
  #
  # == Parameters
  #
  # +ubound+::
  #   Optional. An arbitrary positive number.
  #   The upper bound of enumeration. The method enumerates
  #   prime numbers infinitely if +ubound+ is nil.
  # +generator+::
  #   Optional. An implementation of pseudo-prime generator.
  #
  # == Return value
  #
  # An evaluated value of the given block at the last time.
  # Or an enumerator which is compatible to an +Enumerator+
  # if no block given.
  #
  # == Description
  #
  # Calls +block+ once for each prime number, passing the prime as
  # a parameter.
  #
  # +ubound+::
  #   Upper bound of prime numbers. The iterator stops after it
  #   yields all prime numbers p <= +ubound+.

  # == Parameters
  #
  # +value+:: an arbitrary integer to be checked.
  # +generator+:: optional. A pseudo-prime generator.

      return false if r == 0

# Re-composes a prime factorization and returns the product.
  #
  # == Parameters
  # +pd+:: Array of pairs of integers. The each internal
  #        pair consists of a prime number -- a prime factor --
  #        and a natural number -- an exponent.
  #
  # == Example
  # For <tt>[[p_1, e_1], [p_2, e_2], ...., [p_n, e_n]]</tt>, it returns:
  #
  #   p_1**e_1 * p_2**e_2 * .... * p_n**e_n.
  #
  #   Prime.int_from_prime_division([[2,2], [3,1]])  #=> 12
  def int_from_prime_division(pd)
    pd.inject(1){|value, (prime, index)|
      value * prime**index
    }
  end

# Returns the factorization of +value+.
  #
  # == Parameters
  # +value+:: An arbitrary integer.
  # +generator+:: Optional. A pseudo-prime generator.
  #               +generator+.succ must return the next
  #               pseudo-prime number in the ascending
  #               order. It must generate all prime numbers,
  #               but may also generate non prime numbers too.
  #
  # === Exceptions
  # +ZeroDivisionError+:: when +value+ is zero.
  #
  # == Example
  # For an arbitrary integer:
  #
  #   n = p_1**e_1 * p_2**e_2 * .... * p_n**e_n,
  #
  # prime_division(n) returns:
  #
  #   [[p_1, e_1], [p_2, e_2], ...., [p_n, e_n]].
  #
  #   Prime.prime_division(12) #=> [[2,2], [3,1]]
