Description
| Interface Summary | |
|---|---|
| AppenderAttachable | Interface for attaching appenders to objects. |
| Configurator | Implemented by classes capable of configuring log4j using a URL. |
| ErrorCode | This interface defines commonly encoutered error codes. |
| ErrorHandler | Appenders may delegate their error handling to
ErrorHandlers. |
| HierarchyEventListener | Listen to events occuring within a Hierarchy. |
| LoggerFactory | Implement this interface to create new instances of Logger or a sub-class of Logger. |
| LoggerRepository | A LoggerRepository is used to create and retrieve
Loggers. |
| OptionHandler | A string based interface to configure package components. |
| RendererSupport | |
| RepositorySelector | The LogManager uses one (and only one)
RepositorySelector implementation to select the
LoggerRepository for a particular application context. |
| ThrowableRenderer | Implemented by classes that render instances of java.lang.Throwable (exceptions and errors) into a string representation. |
| ThrowableRendererSupport | Implemented by logger repositories that support configurable rendering of Throwables. |
| TriggeringEventEvaluator | Implementions of this interface allow certain appenders to decide when to perform an appender specific action. |
| Class Summary | |
|---|---|
| DefaultRepositorySelector | |
| Filter | Users should extend this class to implement customized logging event filtering. |
| LocationInfo | The internal representation of caller location information. |
| LoggingEvent | The internal representation of logging events. |
| NOPLogger | No-operation implementation of Logger used by NOPLoggerRepository. |
| NOPLoggerRepository | No-operation implementation of LoggerRepository which is used when LogManager.repositorySelector is erroneously nulled during class reloading. |
| RootCategory | Deprecated. Replaced by RootLogger. |
| RootLogger | RootLogger sits at the top of the logger hierachy. |
| ThrowableInformation | ThrowableInformation is log4j's internal representation of throwables. |
Contains part of the System Programming Interface (SPI) needed to extend log4j.
