public class DataCubeColumn
extends ChildItem<DataCubeColumnData>

Represents the column coordinate in a data cube. A BioAssay must have a link to an item of this type. It is possible for more than one bioassay to link to the same column. Actually, if two BioAssaySet:s, one which is the child of the other, are in the same data cube, a bioassay must link to the same column as the parent bioassay.

DataCubeColumn

DataCubeColumn(DataCubeColumnData data)

Creates a new data cube item from the given data.

Parameters:

data - the data

Method Detail

getNew

static DataCubeColumn getNew(DbControl dc,
                             DataCube cube)
                      throws BaseException

Create a new DataCubeColumn item.

Parameters:

dc - The DbControl which will be used for permission checking and database access.

cube - The cube the new column is located in

Returns:

The new DataCubeColumn item

Throws:

BaseException - If there is an error

getById

public static DataCubeColumn getById(DbControl dc,
                                     int id)
                              throws ItemNotFoundException,

                                     BaseException

Get a DataCubeColumn item when you know the id.

Parameters:

dc - The DbControl which will be used for permission checking and database access.

id - The id of the item to load

Returns:

The DataCubeColumn item

Throws:

ItemNotFoundException - If an item with the specified id is not found

PermissionDeniedException - If the logged in user doesn't have Permission.READ permission to the item

BaseException - If there is another error

getType

public Item getType()

Description copied from interface: Identifiable

A value indicating the type of item

initPermissions

void initPermissions(int granted,
                     int denied)
               throws BaseException

Deny DELETE permission. Columns are automatically deleted when the data cube is deleted (by Hibernate cascade).

Overrides:

initPermissions in class ChildItem<DataCubeColumnData>

Parameters:

granted - Permissions that have been granted by the subclass

denied - Permissions that have been denied by the subclass

Throws:

BaseException - If the permissions couldn't be initialised

getSharedParent

SharedData getSharedParent()

Specified by:

getSharedParent in class ChildItem<DataCubeColumnData>

Returns:

The parent item

getPermissionForWriteDeleteAndCreate

Permission getPermissionForWriteDeleteAndCreate()

USE permission is enough to be able to manage data cubes.

Overrides:

getPermissionForWriteDeleteAndCreate in class ChildItem<DataCubeColumnData>

Get the data cube this layer belongs to.

Returns:

A DataCube object

Throws:

PermissionDeniedException - If the logged in user doesn't have read permission to the item

BaseException - If there is another error

setDataCube

private void setDataCube(DataCube cube)
                  throws PermissionDeniedException,
