                          throws InvalidParameterException,
RepositoryErrorException,
EntityNotKnownException,
UserNotAuthorizedException

Description copied from class: OMRSMetadataCollectionBase

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 OMRSMetadataCollectionBase

Parameters:

userId - unique identifier for requesting user.

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

Returns:

deleted entity

Throws:

InvalidParameterException - one of the parameters is invalid or null.

getEntityNeighborhood

public InstanceGraph getEntityNeighborhood(String userId,
 String entityGUID,
 List<String> entityTypeGUIDs,
 List<String> relationshipTypeGUIDs,
 List<InstanceStatus> limitResultsByStatus,
 List<String> limitResultsByClassification,
 Date asOfTime,

Description copied from class: OMRSMetadataCollectionBase

Return the entities and relationships that radiate out from the supplied entity GUID. The results are scoped both the instance type guids and the level.

Overrides:

getEntityNeighborhood in class OMRSMetadataCollectionBase

Parameters:

userId - unique identifier for requesting user.

entityGUID - the starting point of the query.

entityTypeGUIDs - list of entity types to include in the query results. Null means include all entities found, irrespective of their type.

relationshipTypeGUIDs - list of relationship types to include in the query results. Null means include all relationships found, irrespective of their type.

limitResultsByStatus - By default, relationships in all non-DELETED statuses are returned. However, it is possible to specify a list of statuses (eg ACTIVE) to restrict the results to. Null means all status values except DELETED.

limitResultsByClassification - List of classifications that must be present on all returned entities.

asOfTime - Requests a historical query of the relationships for the entity. Null means return the present values.

level - the number of the relationships out from the starting entity that the query will traverse to gather results.

Returns:

InstanceGraph the sub-graph that represents the returned linked entities and their relationships.

Throws:

InvalidParameterException - one of the parameters is invalid or null.

RepositoryErrorException - there is a problem communicating with the metadata repository where the metadata collection is stored.

EntityNotKnownException - the entity identified by the entityGUID is not found in the metadata collection.

TypeErrorException - the type guid passed on the request is not known by the metadata collection.

PropertyErrorException - there is a problem with one of the other parameters.

FunctionNotSupportedException - the repository does not support this call.

UserNotAuthorizedException - the userId is not permitted to perform this operation.

Description copied from class: OMRSMetadataCollectionBase

Return the list of entities that are of the types listed in entityTypeGUIDs and are connected, either directly or indirectly to the entity identified by startEntityGUID.

Overrides:

getRelatedEntities in class OMRSMetadataCollectionBase

Parameters:

userId - unique identifier for requesting user.

startEntityGUID - unique identifier of the starting entity.

entityTypeGUIDs - list of types to search for. Null means any type.

fromEntityElement - starting element for results list. Used in paging. Zero means first element.

limitResultsByStatus - By default, relationships in all non-DELETED statuses are returned. However, it is possible to specify a list of statuses (eg ACTIVE) to restrict the results to. Null means all status values except DELETED.

limitResultsByClassification - List of classifications that must be present on all returned entities.

asOfTime - Requests a historical query of the relationships for the entity. Null means return the present values.

sequencingProperty - String name of the property that is to be used to sequence the results. Null means do not sequence on a property name (see SequencingOrder).

sequencingOrder - Enum defining how the results should be ordered.

pageSize - the maximum number of result entities that can be returned on this request. Zero means unrestricted return results size.

Returns:

list of entities either directly or indirectly connected to the start entity

Throws:

InvalidParameterException - one of the parameters is invalid or null.

TypeErrorException - one of the type guids passed on the request is not known by the metadata collection.

RepositoryErrorException - there is a problem communicating with the metadata repository where the metadata collection is stored.

EntityNotKnownException - the entity identified by the startEntityGUID is not found in the metadata collection.

PropertyErrorException - the sequencing property specified is not valid for any of the requested types of entity.

PagingErrorException - the paging/sequencing parameters are set up incorrectly.

FunctionNotSupportedException - the repository does not support this call.
