Overrides the default change detection.
|
||
|
|
|
||
|
|
`doCheck()` gets called to check the changes in the directives instead of the default
|
||
|
|
change detection mechanism.
|
||
|
|
|
||
|
|
It is invoked every time the change detection is triggered.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```
|
||
|
|
@Component(...)
|
||
|
|
class MyComponent implements DoCheck {
|
||
|
|
doCheck(): void {
|
||
|
|
// Custom logic to detect changes
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
