| Users should extend this class to implement customized logging | |
| event filtering. Note that <a href="T_log4net_Repository_Hierarchy_Logger.htm" target="">Logger</a> and | |
| <a href="T_log4net_Appender_AppenderSkeleton.htm" target="">AppenderSkeleton</a>, the parent class of all standard | |
| appenders, have built-in filtering rules. It is suggested that you | |
| first use and understand the built-in rules before rushing to write | |
| your own custom filters. | |
| </p><p> | |
| This abstract class assumes and also imposes that filters be | |
| organized in a linear chain. The <a href="M_log4net_Filter_FilterSkeleton_Decide.htm" target="">Decide(LoggingEvent)</a> | |
| method of each filter is called sequentially, in the order of their | |
| addition to the chain. | |
| </p><p> | |
| The <a href="M_log4net_Filter_FilterSkeleton_Decide.htm" target="">Decide(LoggingEvent)</a> method must return one | |
| of the integer constants <a href="T_log4net_Filter_FilterDecision.htm" target="">Deny</a>, | |
| <a href="T_log4net_Filter_FilterDecision.htm" target="">Neutral</a> or <a href="T_log4net_Filter_FilterDecision.htm" target="">Accept</a>. | |
| </p><p> | |
| If the value <a href="T_log4net_Filter_FilterDecision.htm" target="">Deny</a> is returned, then the log event is dropped | |
| immediately without consulting with the remaining filters. | |
| </p><p> | |
| If the value <a href="T_log4net_Filter_FilterDecision.htm" target="">Neutral</a> is returned, then the next filter | |
| in the chain is consulted. If there are no more filters in the | |
| chain, then the log event is logged. Thus, in the presence of no | |
| filters, the default behavior is to log all logging events. | |
| </p><p> | |
| If the value <a href="T_log4net_Filter_FilterDecision.htm" target="">Accept</a> is returned, then the log | |
| event is logged without consulting the remaining filters. | |
| </p><p> | |
| The philosophy of log4net filters is largely inspired from the | |
| Linux ipchains. | |
