DependencySorter
================

[](#dependencysorter)

Sorts items according to a list of dependencies.

This package provides 2 interfaces:

 Iyoworks\\DependencySorter\\SortableInterface implemented by objects that conducting the sorting Iyoworks\\DependencySorter\\DependableInterface implemented by objects that are to be sortedItems can be passed to the sorter in a group via `Sorter::add(array)`, or individuallay via `Sorter::addItem(item, dependencies)`.

The provided `Sorter` implementaion can get dependencies from:

- a comma delimted string
- an array
- an object that implements `DependableInterface`

```
$sorter = new Iyoworks\DependencySorter\Sorter;
$sorter->add( array(
	'couple' => 'father, mother'
	'mother' => 'father',
	'father' => null,
	));
$orderedItems = $sorter->sort();

```

The sorted list of items would be:

```
Array
(
    [0] => father
    [1] => mother
    [2] => couple
)

```

Missing Dependencies
--------------------

[](#missing-dependencies)

Items missing dependencies are identified.

```
$sorter = new Iyoworks\DependencySorter\Sorter;
$sorter->add( array(
	'couple' => 'father, mother'
	'mother' => 'child',
	'father' => 'mother',
	) );
$orderedItems = $sorter->sort(); //returns an empty array

```

The missing dependencies can be retrieved

```
$missing = $sorter->getMissing();

```

The missing items would be:

```
Array
(
    [mother] => Array
        (
            [child] => child
        )
)

```

Missing dependencies of an item can be retrieved individually

```
$missing = $sorter->getMissing('mother');

```

You can check if an item has missing dependencies

```
$sorter->hasMissing($item);

```

You can also check if an item is a missing dependency

```
$sorter->isMissing($dep);

```

Circular Dependencies
---------------------

[](#circular-dependencies)

Circular dependencies are identified.

```
$sorter = new Iyoworks\DependencySorter\Sorter;
$sorter->add( array(
	'couple' => 'father, mother'
	'mother' => 'father',
	'father' => 'mother',
	) );
$orderedItems = $sorter->sort(); //returns an empty array
$circular = $sorter->getCircular();

```

The list of circular items would be:

```
Array
(
    [mother] => Array
        (
            [father] => father
        )
    [father] => Array
        (
            [mother] => mother
        )
)

```

The circular dependencies of an item can be retrieved individually.

```
$circular = $sorter->getCircular('father');

```

You can check if an item has circular dependencies

```
$sorter->hasCircular($item);

```

You can also check if an item is a circular dependency

```
$sorter->isCircular($dep);

```
