SynchroGroupManager (Silverpeas Core 6.4 API)

All Known Implementing Classes:

DefaultSynchroGroupManager
```
public interface SynchroGroupManager
```
This manager maintains a context of synchronized groups in the final aim to perform manual or scheduled synchronizations.
A secondary goal of this manager is to avoid to request the database each time a synchronization is requested. That is why it maintains a context of synchronized group that MUST be updated mainly by administration services.

API Note:

the synchronization group manager MUST be application scoped in order to be handled properly.

Implementation Note:

no @PostConstruct annotation is used to call resetContext() to initialize the context. The reset method is called by Administration implementation.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`static SynchroGroupManager`	`get()`
`void`	`removeFromContext(Group group)`	Removes the given group from the context of the manager.
`void`	`resetContext()`	Resets the context of the manager.

`void`	`updateContextWith(Group group)`	Updates the context of the manager with the given group data.

- Method Detail
  - get
```
static SynchroGroupManager get()
```
  - synchronize
```
void synchronize()
```
    Performs the synchronization of synchronized groups.
    
    API Note:
    
    the synchronized groups are those from the contexts, no database requests are performed.
    
    Implementation Requirements:
    
    implementation takes into account that several call can be performed at a same time.
  - updateContextWith
```
void updateContextWith(Group group)
```
    Updates the context of the manager with the given group data.
    If the group is a synchronized one, then it will be added to the list of group to perform update on. If it is not synchronized, then it is removed from this list.
    
    Parameters:
    
    group - data representing a group.
    
    Throws:
    
    IllegalArgumentException - if group identifier does not exist into data.
  - removeFromContext
```
void removeFromContext(Group group)
```
    Removes the given group from the context of the manager.
    
    Parameters:
    
    group - data representing a group.
    
    Throws:
    
    IllegalArgumentException - if group identifier does not exist into data.
  - resetContext
```
void resetContext()
```
    Resets the context of the manager.
    
    API Note:
    
    it performs mainly the load of synchronized groups from the repository (database).
