Class ModelCrudService

java.lang.Object

com.evolveum.midpoint.model.impl.ModelCrudService

@Component
public class ModelCrudService
extends Object

Simple version of model service exposing CRUD-like operations. This is common facade for webservice and REST services. It takes care of all the "details" of externalized objects such as applying correct definitions and so on. Other methods (not strictly related to CRUD operations) requiring some pre-processing may come here later; if needed for both WS and REST services.

Add new object.

The OID provided in the input message may be empty. In that case the OID will be assigned by the implementation of this method and it will be provided as return value.

This operation should fail if such object already exists (if object with the provided OID already exists).

The operation may fail if provided OID is in an unusable format for the storage. Generating own OIDs and providing them to this method is not recommended for normal operation.

Should be atomic. Should not allow creation of two objects with the same OID (even if created in parallel).

The operation may fail if the object to be created does not conform to the underlying schema of the storage system or the schema enforced by the implementation.

Parameters:

object - object to create

parentResult - parent OperationResult (in/out)

Returns:

OID assigned to the created object

Throws:

ObjectAlreadyExistsException - object with specified identifiers already exists, cannot add

ObjectNotFoundException - object required to complete the operation was not found (e.g. appropriate connector or resource definition)

SchemaException - error dealing with resource schema, e.g. created object does not conform to schema

ExpressionEvaluationException - evaluation of expression associated with the object has failed

CommunicationException

ConfigurationException

PolicyViolationException - Policy violation was detected during processing of the object

IllegalArgumentException - wrong OID format, etc.

SystemException - unknown error from underlying layers or other unexpected state

SecurityViolationException

deleteObject

public <T extends ObjectType> void deleteObject(Class<T> clazz,
 String oid,
 ModelExecuteOptions options,
 Task task,
 OperationResult parentResult)
                                         throws ObjectNotFoundException,
CommunicationException,
SchemaException,
ConfigurationException,
PolicyViolationException,
SecurityViolationException

Deletes object with specified OID.

Must fail if object with specified OID does not exist. Should be atomic.

Parameters:

oid - OID of object to delete

parentResult - parent OperationResult (in/out)

Throws:

ObjectNotFoundException - specified object does not exist

IllegalArgumentException - wrong OID format, described change is not applicable

CommunicationException - Communication problem was detected during processing of the object

ConfigurationException - Configuration problem was detected during processing of the object

PolicyViolationException - Policy violation was detected during processing of the object

SystemException - unknown error from underlying layers or other unexpected state

SchemaException

SecurityViolationException

modifyObject

public <T extends ObjectType> void modifyObject(Class<T> type,
 String oid,
 Collection<? extends ItemDelta<?,?>> modifications,
 ModelExecuteOptions options,
 Task task,
 OperationResult parentResult)
                                         throws ObjectNotFoundException,
SchemaException,
ExpressionEvaluationException,
CommunicationException,
ConfigurationException,
ObjectAlreadyExistsException,
PolicyViolationException,
SecurityViolationException

Modifies object using relative change description.

Must fail if user with provided OID does not exist. Must fail if any of the described changes cannot be applied. Should be atomic.

If two or more modify operations are executed in parallel, the operations should be merged. In case that the operations are in conflict (e.g. one operation adding a value and the other removing the same value), the result is not deterministic.

The operation may fail if the modified object does not conform to the underlying schema of the storage system or the schema enforced by the implementation.

Parameters:

parentResult - parent OperationResult (in/out)

Throws:

ObjectNotFoundException - specified object does not exist

SchemaException - resulting object would violate the schema

ExpressionEvaluationException - evaluation of expression associated with the object has failed

CommunicationException - Communication problem was detected during processing of the object

ObjectAlreadyExistsException - If the account or another "secondary" object already exists and cannot be created

PolicyViolationException - Policy violation was detected during processing of the object

IllegalArgumentException - wrong OID format, described change is not applicable

SystemException - unknown error from underlying layers or other unexpected state

ConfigurationException

SecurityViolationException
