BlobStoreAwareMonitor (OpenNMS 28.0.0 API)

java.lang.Object
- org.opennms.netmgt.threshd.BlobStoreAwareMonitor

All Implemented Interfaces:

ThresholdStateMonitor
```
public class BlobStoreAwareMonitor
extends java.lang.Object
implements ThresholdStateMonitor
```
This implementation tracks the in-memory states of thresholds while also being aware of their persistence. This allows for the encapsulation of atomic clear/reinitialize logic where both the in-memory and persisted copies of the state can be cleared together without clients of being aware.
