FileExtension (powsybl-afs 4.0.4 API)

All Known Implementing Classes:

CaseExtension
```
public interface FileExtension<T extends File>
```
Interface to add a new type of file to the application file system.
In order to add a new type of file to your AppData instance, you need to implement that interface and declare it to the runtime using the AutoService annotation.
The instance needs to define the new class, a name identifying that class ("pseudo class"), and to provide a creation method for those new file objects. For instance:
```
 @AutoService
 public class MyFileExtension implements FileExtension<MyFile> {

    @Override
    public Class getFileClass() { return MyFile.class; }

    @Override
    public String getFilePseudoClass() { return "myFile"; }

    @Override
    public T createFile(FileCreationContext context) { return new MyFileExtension(context); }
 }
 
```
