deleteEntity

public EntityDetail deleteEntity(String userId,
 String typeDefGUID,
 String typeDefName,
 String obsoleteEntityGUID)
                          throws FunctionNotSupportedException

Delete an entity. The entity is soft-deleted. This means it is still in the graph, but it is no longer returned on queries. All homed relationships to the entity are also soft-deleted and will no longer be usable, while any reference copy relationships to the entity will be purged (and will no longer be accessible in this repository). To completely eliminate the entity from the graph requires a call to the purgeEntity() method after the delete() call. The restoreEntity() method will switch an entity back to Active status to restore the entity to normal use; however, this will not restore any of the relationships that were soft-deleted as part of the original deleteEntity() call.

Overrides:

deleteEntity in class InMemoryOMRSMetadataCollection

Parameters:

userId - unique identifier for requesting user.

typeDefGUID - unique identifier of the type of the entity to delete.

typeDefName - unique name of the type of the entity to delete.

obsoleteEntityGUID - String unique identifier (guid) for the entity.

Returns:

deleted entity

Throws:

FunctionNotSupportedException - the repository does not support maintenance of metadata.

public void purgeEntity(String userId,
 String typeDefGUID,
 String typeDefName,
 String deletedEntityGUID)
                 throws FunctionNotSupportedException

Permanently removes a deleted entity from the metadata collection. All relationships to the entity -- both homed and reference copies -- will also be purged to maintain referential integrity within the repository. This request can not be undone.

Overrides:

purgeEntity in class InMemoryOMRSMetadataCollection

Parameters:

userId - unique identifier for requesting user.

typeDefGUID - unique identifier of the type of the entity to purge.

typeDefName - unique name of the type of the entity to purge.
