All Implemented Interfaces:

Configurable, Contextualizable, FileSetCheck

public class RegexpSinglelineCheck
extends AbstractFileSetCheck

Checks that a specified pattern matches a single-line in any file type.

Rationale: This check can be used to prototype checks and to find common bad practice such as calling ex.printStacktrace(), System.out.println(), System.exit(), etc.

5.0
