CompositeCallbackImpl (Java Simon 4.2.0 API)

java.lang.Object
- org.javasimon.callback.CompositeCallbackImpl

All Implemented Interfaces:

Callback, CompositeCallback
```
public final class CompositeCallbackImpl
extends Object
implements CompositeCallback
```
Composite callbacks holds child-callbacks and delegates any operations to all of them. It implements callbacks(), addCallback(Callback) and removeCallback(Callback).

    removeCallback in interface CompositeCallback
    
    Parameters:
    
    callback - removed child-callback
  - removeAllCallbacks
```
public void removeAllCallbacks()
```
    Removes specified callback from this callback, properly cleans up all the removed callbacks.
    
    Specified by:
    
    removeAllCallbacks in interface CompositeCallback
  - cleanup
```
public void cleanup()
```
    Calls deactivate on all children.

    cleanup in interface Callback
  - onStopwatchAdd
```
public void onStopwatchAdd(Stopwatch stopwatch,

                           StopwatchSample sample)
```
    Description copied from interface: Callback
    
    Stopwatch add split event. StopwatchSample valid for the moment after the add is provided because the callback is executed out of synchronized block. It is guaranteed that Split.getStopwatch() will not return null.
    
    Specified by:
    
    onStopwatchAdd in interface Callback
    
    Parameters:
    
    stopwatch - modified Stopwatch
    
    split - added split object
    
    sample - stopwatch sampled after the add
  - onStopwatchStart
```
public void onStopwatchStart(Split split)
```
    Description copied from interface: Callback
    
    Stopwatch start event. Duration of all callbacks is included into the split time! StopwatchSample valid for the moment after the start is provided because the callback is executed out of synchronized block. It is guaranteed that Split.getStopwatch() will not return null.
    
    Specified by:
    
    onStopwatchStart in interface Callback
    
    Parameters:
    
    split - started Split
  - onStopwatchStop
```
public void onStopwatchStop(Split split,
                            StopwatchSample sample)
```
    Description copied from interface: Callback
    
    Stopwatch stop event. This action is executed after the split time is calculated and does not affect the measuring. StopwatchSample valid for the moment after the stop is provided because the callback is executed out of synchronized block. It is guaranteed that Split.getStopwatch() will not return null.
    
    Specified by:
    
    onStopwatchStop in interface Callback
    
    Parameters:
    
    split - stopped Split
    
    sample - stopwatch sampled after the stop
  - onCounterDecrease

                              CounterSample sample)
```
    Description copied from interface: Callback

  - onSimonCreated
```
public void onSimonCreated(Simon simon)
```
    Description copied from interface: Callback
    
    Simon created event is called when Simon is successfully created by the Manager. Runs within the block synchronized on the Manager - this results in high consistency, but it also means that implementations of this method should not take much time.
    
    Specified by:
    
    onSimonCreated in interface Callback
    
    Parameters:
    
    simon - created Simon

public void onSimonDestroyed(Simon simon)
```
    Description copied from interface: Callback
    
    Simon destroyed event is called when Simon is successfully destroyed by the Manager. Runs within the block synchronized on the Manager - this results in high consistency, but it also means that implementations of this method should not take much time.
    
    Specified by:
    
    onSimonDestroyed in interface Callback
    
    Parameters:
    
    simon - destroyed Simon
  - onManagerClear
```
public void onManagerClear()
```
    Description copied from interface: Callback
    
    Event called when the manager is cleared. Runs within the block synchronized on the Manager - this results in high consistency, but it also means that implementations of this method should not take much time.
    
    Specified by:
    
    onManagerClear in interface Callback
  - onManagerMessage
```
public void onManagerMessage(String message)
```
    Description copied from interface: Callback
    
    Message event is used to propagate arbitrary messages from the manager, or it can be used by the other Callback methods internally.
    
    Specified by:
    
    onManagerMessage in interface Callback
    
    Parameters:
    
    message - message text
  - onManagerWarning
