Class UserImporter

java.lang.Object
  org.apache.jackrabbit.core.security.user.UserImporter

All Implemented Interfaces:

ProtectedItemImporter, ProtectedNodeImporter, ProtectedPropertyImporter

public class UserImporter
extends Object
implements ProtectedPropertyImporter, ProtectedNodeImporter

UserImporter implements a DefaultProtectedPropertyImporter that is able to deal with user/group content as defined by the default user related node types present with jackrabbit-core.

The importer is intended to be used by applications that import user content extracted from another repository instance and immediately persist the imported content using Session.save(). Omitting the save call will lead to transient, semi-validated user content and eventually to inconsistencies.

Note the following restrictions:

• The importer will only be initialized if the user manager is an instance of TransientChangeUserManager.
• The importer will only be initialized if the editing session starting this import is the same as the UserManager's Session instance.
• The jcr:uuid property of user and groups is defined to represent the hashed authorizable id as calculated by the UserManager. This importer is therefore not able to handle imports with ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW.
• Importing user/group nodes outside of the hierarchy defined by UserManagerImpl.getUsersPath() and UserManagerImpl.getGroupsPath() will fail upon save as the mandatory properties will not be imported. The same may be true in case of ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING inserting the user/group node at some other place in the node hierarchy.
• While creating user/groups through the API the UserManagerImpl makes sure that authorizables are never nested and are created below a hierarchy of nt:AuthorizableFolder nodes. This isn't enforced by means of node type constraints but only by the API. This importer currently doesn't perform such a validation check.
• Any attempt to import conflicting data will cause the import to fail either immediately or upon calling Session.save() with the following exceptions:
  • rep:members : Group membership
  • rep:impersonators : Impersonators of a User.
  The import behavior of these two properties is defined by the PARAM_IMPORT_BEHAVIOR configuration parameter, which can be set to
  • ignore: A warning is logged.
  • best effort: A warning is logged and the importer tries to fix the problem.
  • abort: The import is immediately aborted with a ConstraintViolationException. (default)

Known Issue:
Importing rep:impersonators property referring to principals that are created during this import AND have principalName different from the ID will no succeed, as the validation in ImpersonationImpl isn't able to find the authorizable with the given principal (reason: query will only find persisted content).

init

public boolean init(JackrabbitSession session,
                    NamePathResolver resolver,
                    boolean isWorkspaceImport,
                    int uuidBehavior,
                    ReferenceChangeTracker referenceTracker)

Specified by:

init in interface ProtectedItemImporter

Returns:

handlePropInfo

public boolean handlePropInfo(NodeImpl parent,
                              PropInfo protectedPropInfo,
                              QPropertyDefinition def)
                       throws RepositoryException

Description copied from interface: ProtectedPropertyImporter

Handles a single protected property.

Specified by:

handlePropInfo in interface ProtectedPropertyImporter

Parameters:

parent - The affected parent node.

protectedPropInfo - The PropInfo to be imported.

def - The property definition determined by the importer that calls this method.

Returns:

true If the property could be successfully imported; false otherwise.

Throws:

RepositoryException - If an error occurs.

handlePropInfo

public boolean handlePropInfo(NodeState parent,
                              PropInfo protectedPropInfo,
                              QPropertyDefinition def)
                       throws RepositoryException

Description copied from interface: ProtectedPropertyImporter

Handles a single protected property.

Specified by:

handlePropInfo in interface ProtectedPropertyImporter

Parameters:

parent - The affected parent node.

protectedPropInfo - The PropInfo to be imported.

def - The property definition determined by the importer that calls this method.

Returns:

true If the property could be successfully imported; false otherwise.

Throws:

RepositoryException - If an error occurs.

processReferences

public void processReferences()
                       throws RepositoryException

Description copied from interface: ProtectedItemImporter

Post processing protected reference properties underneath a protected or non-protected parent node. If the parent is protected it has been handled by this importer already. This method is called from Importer.end().

Specified by:

processReferences in interface ProtectedItemImporter

Throws:

RepositoryException - If an error occurs.

start

public boolean start(NodeImpl protectedParent)
              throws RepositoryException

Description copied from interface: ProtectedNodeImporter

Notifies this importer about the existence of a protected node that has either been created (NEW) or has been found to be existing. This importer implementation is in charge of evaluating the nature of that protected node in order to determine, if it is able to handle subsequent protected or non-protected child nodes in the tree below that parent.

Specified by:

start in interface ProtectedNodeImporter

Parameters:

protectedParent - A protected node that has either been created during the current XML import or that has been found to be existing without allowing same-name siblings.

Returns:

true If this importer is able to deal with the tree that may be present below the given protected Node.

Throws:

RepositoryException - If an error occurs.

start

public boolean start(NodeState protectedParent)

Description copied from interface: ProtectedNodeImporter

Notifies this importer about the existence of a protected node that has either been created (NEW) or has been found to be existing. This importer implementation is in charge of evaluating the nature of that protected node in order to determine, if it is able to handle subsequent protected or non-protected child nodes in the tree below that parent.

Specified by:

start in interface ProtectedNodeImporter

Parameters:

protectedParent - A protected node that has either been created during the current XML import or that has been found to be existing without allowing same-name siblings.

Returns:

true If this importer is able to deal with the tree that may be present below the given protected NodeState.

startChildInfo

public void startChildInfo(NodeInfo childInfo,
                           List<PropInfo> propInfos)
                    throws RepositoryException

Description copied from interface: ProtectedNodeImporter

Informs this importer about a new childInfo and it's properties. If the importer is able to successfully import the given information this method returns silently. Otherwise ConstraintViolationException is thrown, in which case the whole import fails.

In case this importer deals with multiple levels of nodes, it is in charge of maintaining the hierarchical structure (see also {#link endChildInfo()}.

If ProtectedNodeImporter.start(NodeImpl) hasn't been called before, this method returns silently.

Specified by:

startChildInfo in interface ProtectedNodeImporter

Throws:

ConstraintViolationException - If the given infos contain invalid or incomplete data and therefore cannot be properly handled by this importer.

RepositoryException - If another error occurs.

endChildInfo

public void endChildInfo()
                  throws RepositoryException

Description copied from interface: ProtectedNodeImporter

Informs this importer about the end of a child info.

If ProtectedNodeImporter.start(NodeImpl) hasn't been called before, this method returns silently.

Specified by:

endChildInfo in interface ProtectedNodeImporter

Throws:

ConstraintViolationException - If this method is called before all required child information has been imported.

RepositoryException - If another error occurs.

end

public void end(NodeImpl protectedParent)
         throws RepositoryException

Description copied from interface: ProtectedNodeImporter

Informs this importer that the tree to be imported below protectedParent has bee completed. This allows the importer to be reset in order to be able to deal with another call to ProtectedNodeImporter.start(NodeImpl).

If ProtectedNodeImporter.start(NodeImpl) hasn't been called before, this method returns silently.

Specified by:

end in interface ProtectedNodeImporter

Throws:

ConstraintViolationException - If the tree that was imported is incomplete.

RepositoryException - If another error occurs.

end

public void end(NodeState protectedParent)

Description copied from interface: ProtectedNodeImporter

Informs this importer that the tree to be imported below protectedParent has bee completed. This allows the importer to be reset in order to be able to deal with another call to ProtectedNodeImporter.start(NodeState).

If ProtectedNodeImporter.start(NodeState) hasn't been called before, this method returns silently.

Specified by:

end in interface ProtectedNodeImporter

getImportBehavior

public String getImportBehavior()

Returns:

human readable representation of the importBehavior value.

setImportBehavior

public void setImportBehavior(String importBehaviorStr)

Parameters:
