Class SuppressFilterElement

java.lang.Object

com.puppycrawl.tools.checkstyle.filters.SuppressFilterElement

All Implemented Interfaces:

Filter

public class SuppressFilterElement
extends java.lang.Object
implements Filter

This filter element is immutable and processes AuditEvent objects based on the criteria of file, check, module id, line, and column. It rejects an AuditEvent if the following match:

• the event's file name; and
• the check name or the module identifier; and
• (optionally) the event's line is in the filter's line CSV; and
• (optionally) the check's columns is in the filter's column CSV.
