All Implemented Interfaces:

public class HeaderCheck
extends AbstractHeaderCheck

Checks that a source file begins with a specified header. Property headerFile specifies a file that contains the required header. Alternatively, the header specification can be set directly in the header property without the need for an external file.

Notes: In default configuration, if header is not specified, the default value of header is set to null and the check does not rise any violations.
