ObservedMonitorRegistrar (retval 2.3.0 API)

java.lang.Object
- net.groboclown.retval.monitor.ObservedMonitorRegistrar

```
public class ObservedMonitorRegistrar
extends java.lang.Object
```
A singleton that tracks values that have requirements around execution paths.
This exists outside the objects that call here, so that they do not need to allocate information.

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static ObservedMonitor<ProblemContainer>`	`getCheckedInstance()`
`static boolean`	`isCheckedTraceEnabled()`	Is tracing enabled? If not enabled, then more memory efficient versions of objects may be used.
`static ObservedMonitor.Listener`	`registerCheckedInstance(ProblemContainer instance)`	Register a new observable object with the monitor.
`static void`	`setCheckedInstance(ObservedMonitor<ProblemContainer> monitor)`	Allow for runtime replacement of the singleton.

- Method Detail
  - getCheckedInstance
```
@Nonnull
public static ObservedMonitor<ProblemContainer> getCheckedInstance()
```
  - registerCheckedInstance
```
@Nonnull
public static ObservedMonitor.Listener registerCheckedInstance(@Nonnull
                                                               ProblemContainer instance)
```
    Register a new observable object with the monitor. The returned value must be immutable in all but unit test environments.
    
    Parameters:
    
    instance - instance to register
    
    Returns:
    
    a callback listener for when the close action occurs.
  - isCheckedTraceEnabled
```
public static boolean isCheckedTraceEnabled()
```
    Is tracing enabled? If not enabled, then more memory efficient versions of objects may be used.
    
    Returns:
    
    true if close tracing is enabled, false otherwise.
  - setCheckedInstance
```
public static void setCheckedInstance(@Nonnull
                                      ObservedMonitor<ProblemContainer> monitor)
```
    Allow for runtime replacement of the singleton. This is useful for testing or dynamically enabling tracing.
    
    Parameters:
    
    monitor - new monitor to use as the singleton.
