Java
Interface may be annotated as '@FunctionalInterface'
Warning
New
Last modified: 03 December 2024 Reports interfaces that can be annotated with @FunctionalInterface
.
Annotating an interface with @FunctionalInterface
indicates that the interface is functional and no more abstract
methods can be added to it.
Example:
interface FileProcessor {
void execute(File file);
}
After the quick-fix is applied:
@FunctionalInterface
interface FileProcessor {
void execute(File file);
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
