# InvalidTemplateParam
|
|
|
|
Emitted when using the `@extends`/`@implements` annotation to extend a class that has a template type constraint, where that extended value does not satisfy the parent class/interface's constraints.
|
|
|
|
```php
|
|
<?php
|
|
|
|
/**
|
|
* @template T as object
|
|
*/
|
|
class Base {}
|
|
|
|
/** @template-extends Base<int> */
|
|
class SpecializedByInheritance extends Base {}
|
|
```
