com.puppycrawl.tools.checkstyle.checks.sizes.FileLengthCheck

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.
