Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`readLock()`	Acquires a non-exclusive read lock that will cause calls from other threads to `registerMetric(Metric, MetricMetadata)` or `unregister(MetricID)` to block.
`void`	`registerMetric(Metric metric, MetricMetadata metadata)`	Registers the given metric.
`void`	`unlock()`	Releases the non-exclusive lock obtained by a call to `readLock()`.
`void`	`unregister(MetricID metricID)`	Unregisters the given metric, if it is registered.

- Method Detail
  - registerMetric
```
void registerMetric(Metric metric,
                    MetricMetadata metadata)
```
    Registers the given metric. Calls will block if another thread holds the registry read lock.
    
    Parameters:
    
    metric - the metric. Cannot be null
    
    metadata - metadata for the metric. Cannot be null
  - unregister
```
void unregister(MetricID metricID)
```
    Unregisters the given metric, if it is registered. Calls will block if another thread holds the registry read lock.
    
    Parameters:
    
    metricID - the id for the metric. Cannot be null
  - readLock
```
void readLock()
```
    Acquires a non-exclusive read lock that will cause calls from other threads to registerMetric(Metric, MetricMetadata) or unregister(MetricID) to block. Must be followed by a call to unlock().
  - unlock
```
void unlock()
```
    Releases the non-exclusive lock obtained by a call to readLock().
