Method Detail

attachAndMergeLevel

public void attachAndMergeLevel(ModelInstance modelInstance,
                                String level)
                         throws OptimisticLockException

Description copied from interface: ModelInstanceUtilsService

If a model instance is detached it is attached to the original and state of specified evaluation level is merged to lower level. Merge is executed in the existing transaction.

Specified by:

attachAndMergeLevel in interface ModelInstanceUtilsService

Throws:

OptimisticLockException

saveModelInstance

public void saveModelInstance(ModelInstance modelInstance)
                       throws ModelInstanceNotFoundException

Description copied from interface: ModelInstanceUtilsService

Saves model instance to model instance entity.

Specified by:

saveModelInstance in interface ModelInstanceUtilsService

Throws:

ModelInstanceNotFoundException

resetUnchangedRecordVersions

public void resetUnchangedRecordVersions(ModelInstance modelInstance)

Description copied from interface: ModelInstanceUtilsService

Resets version of unchanged versioned higher level shared records.

Specified by:

resetUnchangedRecordVersions in interface ModelInstanceUtilsService

reloadChangedRecordVersions

public void reloadChangedRecordVersions(ModelInstance modelInstance)

Description copied from interface: ModelInstanceUtilsService

Resets version of versioned higher level shared records.

Specified by:

reloadChangedRecordVersions in interface ModelInstanceUtilsService

isDirty

public boolean isDirty(ModelInstance modelInstance)

Description copied from interface: ModelInstanceUtilsService

Returns true if there are changes in no-base evaluation level that can affect existing data in the base level. In other words it returns true if there are unsaved changes in a document or todo.

Specified by:

isDirty in interface ModelInstanceUtilsService

Returns:

true if there are unsaved changes in a document or todo

isDirty

public boolean isDirty(ModelInstance modelInstance,
                       Collection<String> ignoreLevels)

Description copied from interface: ModelInstanceUtilsService

Returns true if there are changes in no-base evaluation level that can affect existing data in the base level. In other words it returns true if there are unsaved changes in a document or todo.

Specified by:

isDirty in interface ModelInstanceUtilsService

ignoreLevels - a collection of levels that should be ignored

Returns:

true if there are unsaved changes in a document or todo

getOptimisticLockConflicts

public Set<RecordValue> getOptimisticLockConflicts(ModelInstance modelInstance,
                                                   Collection<String> levels,
                                                   boolean resetVersionForUnchanged)

Description copied from interface: ModelInstanceUtilsService

Returns records that will have optimistic lock conflicts when merged to base level.

Specified by:

getOptimisticLockConflicts in interface ModelInstanceUtilsService

Returns:

records that will have optimistic lock conflicts when merged to base level

attach

public void attach(ModelInstance modelInstance)

Description copied from interface: ModelInstanceUtilsService

If a model instance is detached it is attached to the original. It means that changes of variables and non-shared records from detached model instance are set to the original model instance. Records created in the detached model instance are added to the original model instance and deleted records are removed. All this is done only if there is no optimistic lock conflicts on changed values. Record change proxy objects are handled as regular records during the attach. The attach does not work for evaluation levels. If evaluation levels are used the method ModelInstanceUtilsService.attachAndMergeLevel(ModelInstance, String) must be used. state of specified evaluation level is merged to lower level. Merge is executed in the existing transaction.

Specified by:

attach in interface ModelInstanceUtilsService

allocateValueIds

public AllocatedModelInstanceResources allocateValueIds(long modelInstanceId,
                                                        long allocatedSize)

Description copied from interface: ModelInstanceUtilsService

Allocates new range of value ids.

Specified by:

allocateValueIds in interface ModelInstanceUtilsService

Returns:

new range of value ids

allocateDetachmentAndValueIds

public AllocatedModelInstanceResources allocateDetachmentAndValueIds(long modelInstanceId,
                                                                     long allocatedSize)

Description copied from interface: ModelInstanceUtilsService

Allocates new range of value ids and detachment id.

Specified by:

allocateDetachmentAndValueIds in interface ModelInstanceUtilsService
