This class MUST be used to compose a unified list of factories and extensions
from several ServiceProviderInterface implementations.

* Full name: `\FastForward\Container\ServiceProvider\AggregateServiceProvider`
* This class implements:
[`\Interop\Container\ServiceProviderInterface`](../../../Interop/Container/ServiceProviderInterface.md)




## Methods


### __construct

Constructs the AggregateServiceProvider.

```php
public __construct(\Interop\Container\ServiceProviderInterface $serviceProviders): mixed
```








**Parameters:**

| Parameter | Type | Description |
|-----------|------|-------------|
| `$serviceProviders` | **\Interop\Container\ServiceProviderInterface** | One or more service providers to aggregate. |





***

### getFactories

Retrieves all service factories from aggregated providers.

```php
public getFactories(): array<string,callable>
```

This method merges the factories from each service provider into a single array.
The factory for this class itself is added under the key of its class name.







**Return Value:**

an associative array of service factories




***

### getExtensions

Retrieves all service extensions from aggregated providers.

```php
public getExtensions(): array<string,callable>
```

This method merges extensions from each provider. If multiple extensions exist for
the same service ID, they are composed in the order they are added using nested closures.







**Return Value:**

an associative array of service extensions



**Throws:**
<p>if any extension is not callable</p>
