CyclicBufferAppender (Logback-Parent 1.5.34 API)

java.lang.Object
- ch.qos.logback.core.spi.ContextAwareBase
- - ch.qos.logback.core.AppenderBase<E>
  - - ch.qos.logback.core.read.CyclicBufferAppender<E>

All Implemented Interfaces:

Appender<E>, ContextAware, FilterAttachable<E>, LifeCycle
```
public class CyclicBufferAppender<E>
extends AppenderBase<E>
```
CyclicBufferAppender stores events in a cyclic buffer of user-specified size. As the name suggests, if the size of the buffer is N, only the latest N events are available.
