IAdvancedEpochManager (Atoti Server Java API - 6.0.26)

All Superinterfaces:

Cloneable, IClone<IAdvancedEpochManager>, IEpochManager

All Known Implementing Classes:

AEpochManager, DistributedEpochManager, EpochManager
```
public interface IAdvancedEpochManager
extends IClone<IAdvancedEpochManager>, IEpochManager
```
Globally manages the epochs for an application instance.
Controls the creation of new epochs, gives access to the latest epoch, and can create version history for multiversion components that want to record their versions.

- Method Detail
  - onCommit
```
void onCommit(IEpoch epoch)
```
    Notifies the epoch manager that a new epoch has been committed.
    This method should NOT call IVersionHistory.onCommit(IEpoch) as the commit may not affect all the histories.
    
    Parameters:
    
    epoch - the epoch of the commit
  - start
```
void start()
```
    Starts the thread executing the epoch management plan.
    This method does nothing when IEpochManagementPolicy.getInvokeInterval() returns a negative value.
  - isStarted
```
boolean isStarted()
```
    Indicates whether this epoch manager has been started or not.
    
    Returns:
    
    true if this epoch manager has been started, false otherwise
  - stop
```
void stop()
```
    Stops the thread started by start().
  - getRootHistory
```
IVersionHistory<?> getRootHistory()
```
    Description copied from interface: IEpochManager
    
    Gets the root history. The root history is the single history whose versions are followed by other histories.
    
    Specified by:
    
    getRootHistory in interface IEpochManager
    
    Returns:
    
    the root history
  - getHistories
```
Map<String,? extends IVersionHistory<?>> getHistories()
```
    Description copied from interface: IEpochManager
    
    Gets the underlying histories indexed by their ids.
    
    Specified by:
    
    getHistories in interface IEpochManager
