All Superinterfaces:

All Known Subinterfaces:

BinBatchAdminSession

public interface BinAdminSession
extends OsidSession

This session creates, updates, and deletes Bins. The data for create and update is provided by the consumer via the form object. OsidForms are requested for each create or update and may not be reused.

Create and update operations differ in their usage. To create a Bin, a BinForm is requested using getBinFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned BinForm will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the BinForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each BinForm corresponds to an attempted transaction.

For updates, BinForms are requested to the Bin Id that is to be updated using getBinFormForUpdate(). Similarly, the BinForm has metadata about the data that can be updated and it can perform validation before submitting the update. The BinForm can only be used once for a successful update and cannot be reused.

The delete operations delete Bins.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

Method Detail

canCreateBins

boolean canCreateBins()

Tests if this user can create Bins. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Bin will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer create operations to unauthorized users.

Returns:

false if Bin creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateBinWithRecordTypes

boolean canCreateBinWithRecordTypes(Type[] binRecordTypes)

Tests if this user can create a single Bin using the desired record types. While ResourceManager.getBinRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Bin. Providing an empty array tests if a Bin can be created with no records.

Parameters:

binRecordTypes - array of bin record types

Returns:

true if Bin creation using the specified Types is supported, false otherwise

Throws:

NullArgumentException - binRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getBinFormForCreate

BinForm getBinFormForCreate(Type[] binRecordTypes)
                            throws OperationFailedException,
                                   PermissionDeniedException

Gets the bin form for creating new bins.

Parameters:

binRecordTypes - array of bin record types

Returns:

the bin form

Throws:

NullArgumentException - binRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form with requested record types

Compliance:

mandatory - This method must be implemented.

createBin

Bin createBin(BinForm binForm)
              throws OperationFailedException,
                     PermissionDeniedException

Creates a new Bin.

Parameters:

binForm - the form for this Bin

Returns:

the new Bin

Throws:

IllegalStateException - binForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - binForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - binForm did not originate from getBinFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateBins

boolean canUpdateBins()

Tests if this user can update Bins. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a Bin will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer update operations to unauthorized users.

Returns:

false if Bin modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getBinFormForUpdate

BinForm getBinFormForUpdate(Id binId)
                            throws NotFoundException,
                                   OperationFailedException,
                                   PermissionDeniedException

Gets the bin form for updating an existing bin. A new bin form should be requested for each update transaction.

Parameters:

binId - the Id of the Bin

Returns:

the bin form

Throws:

NotFoundException - binId is not found

NullArgumentException - binId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

updateBin

void updateBin(BinForm binForm)
               throws OperationFailedException,
                      PermissionDeniedException

Updates an existing bin.

Parameters:

binForm - the form containing the elements to be updated

Throws:

IllegalStateException - binForm already used in an update transaction

InvalidArgumentException - the form contains an invalid value

NullArgumentException - binId or binForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - binForm did not originate from getBinFormForUpdate()

Compliance:

mandatory - This method must be implemented.

canDeleteBins

boolean canDeleteBins()

Tests if this user can delete Bins. A return of true does not guarantee successful authorization. A return of false indicates that it is known deleting a Bin will result in a PERMISSION_DENIED.

mandatory - This method must be implemented.

canManageBinAliases

boolean canManageBinAliases()

Tests if this user can manage Id aliases for Bins. A return of true does not guarantee successful authorization.

Returns:

false if Bin aliasing is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.
