|
||||
== The `Horse` class
|
||||
|
||||
The `Horse` class, unsurprisingly, represents a horse.
|
||||
|
||||
Each horse has:
|
||||
|
||||
* A name
|
||||
* An age
|
||||
* An assigned starting number
|
||||
|
||||
During the race and based on the race results each horse gets assigned:
|
||||
|
||||
* A varying position
|
||||
* A final rank
|
||||
|
||||
=== Method Requirements
|
||||
|
||||
Additional specifications for some methods -- primarily rely on the XML Doc.
|
||||
|
||||
* `CompareTo`
|
||||
** Subtract _from_ the `other` value to get the correct `int` value
|
||||
* `Move`
|
||||
** The probability of moving one position ('field') forward is ~33%
|
||||
*** Make sure to use the `Random` instance in `RandomProvider`
|
||||
* `TryParse`
|
||||
** The name cannot be empty
|
||||
** The age of a horse has to be in the stem:[0 < x <= 20] range
|
||||
** The starting number may not be negative
|
||||
|
||||
== Importing Data with the `HorseImporter` class
|
||||
|
||||
The `Horse` class provides a `TryParse` _factory method_, yet it still needs to be called for each CSV line which in turn needs to be read from a file.
|
||||
That is the job of the `_static_` `HorseImporter` class.
|
||||
|
||||
Consider the usual rules for reading CSV files:
|
||||
|
||||
* The file has to exist
|
||||
* It has to have a header and _at least one_ valid data row
|
||||
* Invalid data rows are skipped
|
||||
* If no data could be parsed an _empty_ array is returned
|
||||
* Make sure the returned array does not contain any `null` values
|
||||
|
||||
NOTE: This is a `static` class providing a single, _stateless_ method
|
||||
|
||||
== Performing the race with the `HorseRace` class
|
||||
|
||||
A race can only happen when the horses are present.
|
||||
Thus, it is _dependent_ on the array of horses => required to construct an instance of the `HorseRace` class.
|
||||
|
||||
* The `IsFinished` property is set to `true` once the first horse reaches the finish line
|
||||
** Subsequent move operations are ignored
|
||||
** The finish line is reached when the horse's `Position` equals `MAX_STEPS`
|
||||
* `MoveHorses` applies a 'move order' to _each_ of the horses in the race
|
||||
* Make sure to print in the expected format
|
||||
** => see sample run below
|
||||
** Remember that the `Horse` class already provides a `Draw` method!
|
||||
* Ranks are assigned based on the position (at the end of the race), thus, horses with the same position also have the same rank
|
||||
** Ranks start at 1 (not 0)
|
||||
* When sorting make sure to use the `CompareTo` method of the `Horse` class
|
||||
** Horses know how to compare to each other _themselves_!
|
||||
|
||||
NOTE: Do not worry about (already implemented) the delay between horse movements. We'll discuss various methods for adding delays to a program in a few months
