# olivebbs/map

Very simple typed map class.


Includes IntCharMap and CharMap as examples.  It is best to extend `Olivebbs\Map\GenericMap `for your uses.

### Example

```php
use Olivebbs\Map\GenericMap;
use Olivebbs\Map\Enum\ValueType;
use Olivebbs\Map\Enum\KeyType;

final class MyStringMap extends GenericMap 
{
    public function __construct(array $values)
    {
        parent::__construct(KeyType::STRING, ValueType::STRING);
        $this->map->putAll($values);
    }
}
```

or

```php
use Olivebbs\Map\GenericMap;
use Olivebbs\Map\Enum\ValueType;
use Olivebbs\Map\Enum\KeyType;

$myIntMap = new GenericMap(KeyType::INT, ValueType::INT); 
```
Then use it.
```php 
$myIntMap[0] = 500;
unset($myIntMap[0]) // null
```
