= FlexArray -- Live Coding Workshop
|
||||
|
||||
Implementation of an ArrayList with automatic growth.
|
||||
We do it manually at least once before starting to use `List<T>`.
|
||||
|
||||
== Project Setup
|
||||
|
||||
Create a new project called `FlexArrays` in an _empty_ directory.
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
// install templates if not done already
|
||||
// dotnet new install HTLLeonding.Utility.Templates
|
||||
|
||||
dotnet new leoconsole -n FlexArrays -o .
|
||||
----
|
||||
|
||||
== Flexible array for `int`
|
||||
|
||||
=== Construction
|
||||
|
||||
As usual, we start with a test.
|
||||
|
||||
.FlexArrayIntTests.cs
|
||||
[source,csharp]
|
||||
----
|
||||
[Fact]
|
||||
public void Construction_NoSize()
|
||||
{
|
||||
var array = new FlexArrayInt();
|
||||
|
||||
array.Should().NotBeNull();
|
||||
array.Count.Should().Be(0, "no items added yet");
|
||||
array.Capacity.Should().Be(FlexArrayInt.DefaultStartSize, "default capacity");
|
||||
}
|
||||
----
|
||||
|
||||
To allow the application to compile we need the class `FlexArrayInt`.
|
||||
|
||||
.FlexArrayInt.cs
|
||||
[source,csharp]
|
||||
----
|
||||
public sealed class FlexArrayInt
|
||||
{
|
||||
public const int DefaultStartSize = 4;
|
||||
private int[] _data;
|
||||
|
||||
public FlexArrayInt(int? initialSize = null) <1>
|
||||
{
|
||||
var size = Math.Max(0, initialSize ?? DefaultStartSize); <2>
|
||||
_data = new int[size];
|
||||
Count = 0;
|
||||
}
|
||||
|
||||
public int Count { get; private set; } <3>
|
||||
public int Capacity => _data.Length; <4>
|
||||
}
|
||||
----
|
||||
<1> Providing an initial capacity is optional
|
||||
<2> Ensuring only valid values are passed
|
||||
<3> We will adjust that value every time an item is added or removed
|
||||
<4> The _current_ max. capacity of the list, will change when a _growth_ happens
|
||||
|
||||
*Turn on continuous testing now!*
|
||||
|
||||
Time for more tests.
|
||||

||||

array.Should().NotBeNull();

|

|
||||
=== Adding items
|
||||
|
||||
The list has been created, now we need to be able to add elements to it.
|
||||
|
||||
.FlexArrayIntTests.cs
|
||||
[source,csharp]
|
||||
----
|
||||
[Fact]
|
||||
public void AddItem_Single()
|
||||
{
|
||||
var array = new FlexArrayInt();
|
||||
|
||||
array.Add(17);
|
||||
|
||||
array.Count.Should().Be(1, "one item added");
|
||||
array.Capacity.Should().Be(FlexArrayInt.DefaultStartSize, "capacity unchanged");
|
||||
}
|
||||
----
|
||||
|
||||
.FlexArrayInt.cs
|
||||
[source,csharp]
|
||||
----
|
||||
public void Add(int value)
|
||||
{
|
||||
if (Capacity == Count) <1>
|
||||
{
|
||||
Grow(); <1>
|
||||
}
|
||||
_data[Count++] = value; <2>
|
||||
}
|
||||
|
||||
private void Grow()
|
||||
{
|
||||
// TODO
|
||||
}
|
||||
----
|
||||
<1> If we are out of free space we have to grow
|
||||
<2> Adding the element to the end of the list
|
||||
|
||||
The basic functionality is showing 'green', but does our solution work when adding multiple items?
|
||||
|
||||
.FlexArrayIntTests.cs
|
||||
[source,csharp]
|
||||
----
|
||||
[Fact]
|
||||
public void AddItem_Multiple_NoGrowth()
|
||||
{
|
||||
var array = new FlexArrayInt();
|
||||
|
||||
array.Add(17);
|
||||
array.Add(20);
|
||||
array.Add(-100);
|
||||
|
||||
array.Count.Should().Be(3, "three items added");
|
||||
array.Capacity.Should().Be(FlexArrayInt.DefaultStartSize, "no growth required yet");
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void AddItem_Multiple_Growth()
|
||||
{
|
||||
var array = new FlexArrayInt();
|
||||
|
||||
void AddItems(int count) <1>
|
||||
{
|
||||
for (var i = 0; i < count; i++)
|
||||
{
|
||||
array.Add(i + 1);
|
||||
}
|
||||
}
|
||||
|
||||
AddItems(FlexArrayInt.DefaultStartSize);
|
||||
array.Capacity.Should().Be(FlexArrayInt.DefaultStartSize);
|
||||
|
||||
AddItems(2);
|
||||
array.Capacity.Should().BeGreaterThan(FlexArrayInt.DefaultStartSize, "capacity exceeded, had to grow"); <2>
|
||||
array.Count.Should().Be(FlexArrayInt.DefaultStartSize + 2);
|
||||
}
|
||||
----
|
||||
<1> Using a local function to reduce code duplication
|
||||
<2> The list had to grow, but we do not constrain in the test how much it has grown -- that is an implementation detail and up to the list => we (usually) test expected _behaviour_ & _functionality_, not how it is accomplished
|
||||
|
||||
The test is 'red' => we haven't implemented growth logic yet.
|
||||
|
||||
.FlexArrayInt.cs
|
||||
[source,csharp]
|
||||
----
|
||||
private void Grow()
|
||||
{
|
||||
var newData = new int[Capacity * 2]; <1>
|
||||
Array.Copy(_data, newData, Count); <2>
|
||||
_data = newData; <3>
|
||||
}
|
||||
----
|
||||
<1> Out growth strategy is to double the size of the array every time -- the more items we add to the list the more space is initially 'wasted'. We could also apply logarithmic scale or a combination; varying scaling factors etc. -- profiling would be required to find a good solution.
|
||||
<2> Don't forget to copy the data from the old array or the values the user added will be lost
|
||||
<3> Replacing the reference to the new array -- the old one will be GC'd
|
||||
|
||||
=== Contains
|
||||
|
||||
Next, we want to check if our list contains a certain element.

||||

=== Accessing items by index
|
||||
|
||||
We want to get items out of the list by index.
|
||||
This will also allow us to iterate it using a `for` loop.

|
||||
=== Removing items
|
||||
|
||||
Finally, we need to be able to remove items from the list.
|
||||
|
||||
We will provide two options:
|
||||
|
||||
. Remove by index
|
||||
. Remove values
|
||||
.. First occurrence
|
||||
.. All occurrences
|
||||
|
||||
The critical thing is, that we cannot allow 'gaps' in our backing array, so we'll have to _shift_ remaining values.
|
||||
This also highlights the primary weakness of an ArrayList.

<2> Why don't we have to set the last index (to the right) to `null`? Didn't we just duplicate a value that is now in the list twice? No, because we reduce the `Count`, so the duplicated value is now 'out of scope'.

<1> Re-use existing functionality whenever possible
|
||||
<2> Why do we have to decrement the loop index here?
|
||||
<3> `RemoveAt` will modify `Count` -- but we need `Count` for our loop, why does that work? Could we use a `foreach` loop?
|
||||
|
||||
NOTE: Why aren't we shrinking the array again if a sufficient amount of items has been removed?
|
||||
Because that would require yet another copy operation and 'wasting' some memory is usually more efficient than spending cycles.
|
||||
What many array list implementation do is to provide a dedicated `Trim` operation, so the user can actively decide when they want to spend the cycles to reduce the memory footprint.
|
||||
|
||||
== Flexible array for `string`
|
||||
|
||||
Implement the same functionality for `string` instead of `int`.
