  19. * Translates the given message.
  20. *
  21. * When a number is provided as a parameter named "%count%", the message is parsed for plural
  22. * forms and a translation is chosen according to this number using the following rules:
  23. *
  24. * Given a message with different plural translations separated by a
  25. * pipe (|), this method returns the correct portion of the message based
  26. * on the given number, locale and the pluralization rules in the message
  27. * itself.
  28. *
  29. * The message supports two different types of pluralization rules:
  30. *
  31. * interval: {0} There are no apples|{1} There is one apple|]1,Inf] There are %count% apples
  32. * indexed: There is one apple|There are %count% apples
  33. *
  34. * The indexed solution can also contain labels (e.g. one: There is one apple).
  35. * This is purely for making the translations more clear - it does not
  36. * affect the functionality.
  37. *
  38. * The two methods can also be mixed:
  39. * {0} There are no apples|one: There is one apple|more: There are %count% apples
  40. *
  41. * An interval can represent a finite set of numbers:
  42. * {1,2,3,4}
  43. *
  44. * An interval can represent numbers between two numbers:
  45. * [1, +Inf]
  46. * ]-1,2[
  47. *
  48. * The left delimiter can be [ (inclusive) or ] (exclusive).
  49. * The right delimiter can be [ (exclusive) or ] (inclusive).
  50. * Beside numbers, you can use -Inf and +Inf for the infinite.
