                                throws PortalException

Description copied from interface: StagedModelDataHandler

Deletes the staged model matching the parameters. This method is called when deletions are imported.

Parameters:

uuid - the staged model's UUID

groupId - the primary key of the entity's group

Throws:

PortalException - if a portal exception occurred

importCompanyStagedModel

@Deprecated
public void importCompanyStagedModel(PortletDataContext portletDataContext,

importMissingReference

public void importMissingReference(PortletDataContext portletDataContext,
                                   Element referenceElement)
                            throws PortletDataException

Description copied from interface: StagedModelDataHandler

Maps the ID of the existing staged model to the old ID in the reference element. When a reference is exported as missing, the Data Handler framework calls this method during the import process and updates the new primary key map in the portlet data context.

Specified by:

importMissingReference in interface StagedModelDataHandler<T extends StagedModel>

Parameters:

portletDataContext - the portlet data context of the current process

referenceElement - the XML element that contains information about the staged model reference

Throws:

PortletDataException - if a portlet data exception occurred

importMissingReference

public void importMissingReference(PortletDataContext portletDataContext,
                                   String uuid,
                                   long groupId,
                                   long classPK)
                            throws PortletDataException

Description copied from interface: StagedModelDataHandler

Maps the ID of the existing staged model to the old ID in the reference element. When the staged model data handler instance extends BaseStagedModelDataHandler, this method is called to override the importMissingReference(PortletDataContext, Element) and doImportMissingReference(PortletDataContext, Element) methods.

Specified by:

importMissingReference in interface StagedModelDataHandler<T extends StagedModel>

Parameters:

portletDataContext - the portlet data context of the current process

uuid - the staged model's UUID from the reference element

groupId - the primary key of the entity's group from the reference element

classPK - the class primary key of the staged model from the reference element

Throws:

PortletDataException - if a portlet data exception occurred

                              T stagedModel)
                       throws PortletDataException

Description copied from interface: StagedModelDataHandler

Imports the staged model. All the staged model's references must be imported before this method is called. See the importStagedModel(PortletDataContext, StagedModel) method for a reference implementation. Refrain from overriding this method; instead, override the BaseStagedModelDataHandler#doImportStagedModel(PortletDataContext, T) method.

Specified by:

importStagedModel in interface StagedModelDataHandler<T extends StagedModel>

Parameters:

portletDataContext - the portlet data context of the current process

                        throws PortletDataException

Description copied from interface: StagedModelDataHandler

Restores the staged model from the trash. This method is called during the import process to ensure the imported staged model is not in the trash. See the restoreStagedModel(PortletDataContext, StagedModel) method for a reference implementation. Refrain from overriding this method; instead, override the doRestoreStagedModel(PortletDataContext, StagedModel) method.

Specified by:

restoreStagedModel in interface StagedModelDataHandler<T extends StagedModel>

Parameters:

portletDataContext - the portlet data context of the current process

stagedModel - the staged model to restore from the trash

Throws:

PortletDataException - if a portlet data exception occurred
