MetricsWALSourceImpl (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.metrics.BaseSourceImpl
- - org.apache.hadoop.hbase.regionserver.wal.MetricsWALSourceImpl

All Implemented Interfaces:

BaseSource, MetricsWALSource, org.apache.hadoop.metrics2.MetricsSource
```
@InterfaceAudience.Private
public class MetricsWALSourceImpl
extends BaseSourceImpl
implements MetricsWALSource
```
Class that transitions metrics from MetricsWAL into the metrics subsystem. Implements BaseSource through BaseSourceImpl, following the pattern.
