   This filter drops all logging events. 


You can add this filter to the end of a filter chain to switch from the default "accept all unless instructed otherwise" filtering behaviour to a "deny all unless instructed otherwise" behaviour. @author Ceki Gülcü @since 0.9.0 */ public class DenyAllFilter extends Filter { /** Returns null as there are no options. @deprecated We now use JavaBeans introspection to configure components. Options strings are no longer needed. */ public String[] getOptionStrings() { return null; } /** No options to set. @deprecated Use the setter method for the option directly instead of the generic setOption method. */ public void setOption(String key, String value) { } /** Always returns the integer constant {@link Filter#DENY} regardless of the {@link LoggingEvent} parameter. @param event The LoggingEvent to filter. @return Always returns {@link Filter#DENY}. */ public int decide(LoggingEvent event) { return Filter.DENY; } }
