Interface CommitmentAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

CommitmentBatchAdminSession

public interface CommitmentAdminSession
extends OsidSession

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

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

The delete operations delete Commitment. To unmap a Commitment from the current Calendar, the CommitmentCalendarAssignmentSession should be used. These delete operations attempt to remove the Commitment itself thus removing it from all known Calendar catalogs.

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

Method Detail

getCalendarId

Id getCalendarId()

Gets the Calendar Id associated with this session.

Returns:

the Calendar Id associated with this session

Compliance:

mandatory - This method must be implemented.

getCalendar

                     throws OperationFailedException,
                            PermissionDeniedException

Gets the Calendar associated with this session.

Returns:

the Calendar associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateCommitments

boolean canCreateCommitments()

Tests if this user can create Commitments. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Commitment 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.

false if Commitment creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateCommitmentWithRecordTypes

boolean canCreateCommitmentWithRecordTypes(Type[] commitmentRecordTypes)

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

Parameters:

commitmentRecordTypes - array of comitment record types

Returns:

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

Throws:

NullArgumentException - commitmentRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getCommitmentFormForCreate

CommitmentForm getCommitmentFormForCreate(Id eventId,
                                        Id resourceId,
                                        Type[] commitmentRecordTypes)
                                          throws NotFoundException,

Throws:

NotFoundException - eventId or resourceId is not found

NullArgumentException - eventId or resourceId or commitmentRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested recod types

Compliance:
