Class CrowdGroupManager

java.lang.Object
  com.atlassian.crowd.integration.atlassianuser.CrowdGroupManager

All Implemented Interfaces:

com.atlassian.user.EntityManager, com.atlassian.user.GroupManager

public class CrowdGroupManager
extends java.lang.Object
implements com.atlassian.user.GroupManager

Crowd implementation of the atlassian-user group manager.

A group manager is responsible for all CRUD operations on groups and group memberships in a given repository.

Where an operation requires a Group as an argument, calling the method with a group from another repository will typically throw an IllegalArgumentException.

The group manager is responsible for ensuring the consistency of the underlying repository where relevant. For example, if membership information needs to be updated as part of the removeGroup(Group) operation, the group manager is responsible for ensuring it happens.

This interface is an extension of the EntityManager interface which is common to user and group management. The common functionality includes initialisation and access to the repository description.
