getServiceInterface

public final java.lang.Class<? extends ServiceInterface> getServiceInterface()

Specified by:

getServiceInterface in interface SelfConfigurableService

checkImageDelete

public java.util.List<IObject> checkImageDelete(long id,
                                                boolean force)

Description copied from interface: IDelete

Returns all entities which would prevent the given Image id from being deleted. The force boolean determines whether or not the user's collections should be removed in order to facilitate the delete. Currently this only includes datasets. The force boolean determines if Dataset instances from the same user will be considered as constraints. Regardless of force, datasets from other users are considered constraints.

Specified by:

checkImageDelete in interface IDelete

Parameters:

id - of the Image to be deleted.

force - return value will be included

Returns:

unloaded entity list

previewImageDelete

public java.util.List<IObject> previewImageDelete(long id,
                                                  boolean force)

This uses IMAGE_QUERY to load all the subordinate metadata of the Image which will be deleted.

Specified by:

previewImageDelete in interface IDelete

Returns:

unloaded entity list

deleteImage

public void deleteImage(long id,
                        boolean force)
                 throws SecurityViolation,
                        ValidationException

Description copied from interface: IDelete

Deletes an Image and all related (subordinate) metadata as defined below. This method calls IDelete.checkImageDelete(long, boolean) and throws a ConstraintViolationException with the results of that call are not empty; then it forcibly deletes all objects returned by IDelete.previewImageDelete(long, boolean)

The deleted metadata includes all of the following types which belong to the current user:

• Pixels
• PlaneInfo
• RenderingDef
• OriginalFile
• ImageAnnotationLink

If any of these types do not belong to the current user, the Image data graph will be considered corrupted and a ValidationException will be thrown.

For the types:

• Thumbnail

a forced deletion will take place even if the user information does not match the current user.

If the Image is not owned by the current user, then SecurityViolation is thrown, unless the user is root or the group leader.

An image will not be deleted if it is contained in a Dataset owned by another user. If the Image is contained in other datasets belonging to the same user, then the force parameter decides what will happen. A force value of true implies that the Image will be removed as well as the related links. The Pixels.getRelatedTo() field will be set to null for all Pixels pointing to a Pixels instance which is about to be deleted.

Specified by:

deleteImage in interface IDelete

Parameters:

id - id of the Image to be deleted

force - Image will be removed even if contained in other datasets. If false, a ConstraintViolationException will be raised.

Throws:

SecurityViolation - If the Image does not belong to the current user.

ValidationException - throws an exception if there is any unexpected object which prevents this object from being deleted, i.e. not in IDelete.checkImageDelete(long, boolean) (check first)

deleteImages

public void deleteImages(java.util.Set<java.lang.Long> ids,
                         boolean force)
                  throws SecurityViolation,
                         ValidationException,
                         ApiUsageException

Description copied from interface: IDelete

Deletes several Image instances within a single transaction via the IDelete.deleteImage(long, boolean) method.

Specified by:

deleteImages in interface IDelete

Parameters:

ids - As IDelete.deleteImage(long, boolean)

force - As IDelete.deleteImage(long, boolean)

Throws:

SecurityViolation - As IDelete.deleteImage(long, boolean)

ValidationException - As IDelete.deleteImage(long, boolean)

ApiUsageException - As IDelete.deleteImage(long, boolean)

deleteImagesByDataset

public void deleteImagesByDataset(long datasetId,
                                  boolean force)
                           throws SecurityViolation,
                                  ValidationException,
                                  ApiUsageException

Description copied from interface: IDelete

Deletes the user-visible Image instances of the given Dataset within a single transaction via the IDelete.deleteImage(long, boolean). In addition, before Image deletion is attempted, the links to the given Dataset are first removed, otherwise this method would always require a "force" argument of true.

Specified by:

deleteImagesByDataset in interface IDelete

Parameters:

datasetId - As IDelete.deleteImage(long, boolean)

force - As IDelete.deleteImage(long, boolean)

Throws:

SecurityViolation - As IDelete.deleteImage(long, boolean)

ValidationException - As IDelete.deleteImage(long, boolean)

ApiUsageException - As IDelete.deleteImage(long, boolean)

deleteSettings

public void deleteSettings(long imageId)

Description copied from interface: IDelete

Deletes all rendering settings for the given Pixel id. This removes all the same objects that deleteImage() would delete below the given Pixels

Specified by:

deleteSettings in interface IDelete

deleteChannels

public void deleteChannels(long imageId)

deletePlate

public void deletePlate(long plateId)

Description copied from interface: IDelete

Deletes all the images contained in a plate as if deleted by: deleteImage(id, true) so that all Dataset and Annotation links are broken, with WellSamples removed first. Then all Wells in the Plate and the Plate itself are removed. WellAnnotationLinks, and PlateAnnotationLinks are deleted as necessary.

Specified by:

deletePlate in interface IDelete

getImageAndCount

protected void getImageAndCount(Image[] images,
                                long id,
                                ome.services.delete.UnloadedCollector delete)

Uses the locally defined query to load an Image and calls collect(UnloadedCollector, Image) in order to define a list of what will be deleted. This method fulfills the previewImageDelete(long, boolean) contract and as such is used by deleteImage(long, boolean) in order to fulfill its contract.

collect

protected void collect(ome.services.delete.UnloadedCollector delete,
                       Image i)

Walks the Image graph collecting unloaded instances of all entities for later delete.
