All Implemented Interfaces:

Configurable, Contextualizable, FileSetCheck
```
public class FileLengthCheck
extends AbstractFileSetCheck
```
Checks for long source files.

Rationale: If a source file becomes very long it is hard to understand. Therefore, long classes should usually be refactored into several individual classes that focus on a specific task.
- Property fileExtensions - Specify the file extensions of the files to process. Type is java.lang.String[]. Default value is "".
- Property max - Specify the maximum number of lines allowed. Type is int. Default value is 2000.
