Interface MessageAdminSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

All Known Subinterfaces:

MessageBatchAdminSession

public interface MessageAdminSession
extends OsidSession

This session creates, updates, and deletes Messages. 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 Message, a MessageForm is requested using getMessageFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned MessageForm 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 MessageForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each MessageForm corresponds to an attempted transaction.

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

The delete operations delete Messages. To unmap a Message from the current Mailbox, the MessageMailboxAssignmentSession should be used. These delete operations attempt to remove the Message itself thus removing it from all known Mailbox catalogs.

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

Method Detail

getMailboxId

Id getMailboxId()

Gets the Mailbox Id associated with this session.

Returns:

the Mailbox Id associated with this session

Compliance:

mandatory - This method must be implemented.

getMailbox

Mailbox getMailbox()
                   throws OperationFailedException,
                          PermissionDeniedException

Gets the Mailbox associated with this session.

Returns:

the Mailbox associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateMessages

boolean canCreateMessages()

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

Returns:

false if Message creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateMessageWithRecordTypes

boolean canCreateMessageWithRecordTypes(Type[] messageRecordTypes)

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

Parameters:

messageRecordTypes - array of message record types

Returns:

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

Throws:

NullArgumentException - messageRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getMessageFormForCreate

MessageForm getMessageFormForCreate(Type[] messageRecordTypes)
                                    throws OperationFailedException,
                                           PermissionDeniedException

Gets the message form for creating new messages. A new form should be requested for each create transaction.

Parameters:

messageRecordTypes - array of message record types

Returns:

the message form

Throws:

NullArgumentException - messageRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createMessage

Message createMessage(MessageForm messageForm)
                      throws OperationFailedException,
                             PermissionDeniedException

Creates a new Message.

Parameters:

messageForm - the form for this Message

Returns:

the new Message

Throws:

IllegalStateException - messageForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - messageForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - messageForm did not originate from getMessageFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateMessages

boolean canUpdateMessages()

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

Returns:

false if Message modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getMessageFormForUpdate

MessageForm getMessageFormForUpdate(Id messageId)
                                    throws NotFoundException,
