FileCache (SonarQube 4.1.2 API)

```
public class FileCache
extends Object
```
This class is responsible for managing Sonar batch file cache. You can put file into cache and later try to retrieve them. MD5 is used to differentiate files (name is not secure as files may come from different Sonar servers and have same name but be actually different, and same for SNAPSHOTs).
