Defines route lifecycle method [canReuse], which is called by the router to determine whether a
|
|
component should be reused across routes, or whether to destroy and instantiate a new component.
|
|
|
|
If `canReuse` returns or resolves to `true`, the component instance will be reused.
|
|
|
|
If `canReuse` throws or rejects, the navigation will be cancelled.
|
|
|
|
## Example
|
|
```
|
|
@Directive({
|
|
selector: 'my-cmp'
|
|
})
|
|
class MyCmp implements CanReuse, OnReuse {
|
|
canReuse(next, prev) {
|
|
return next.params.id == prev.params.id;
|
|
}
|
|
|
|
onReuse(next, prev) {
|
|
this.id = next.params.id;
|
|
}
|
|
}
|
