Interface EntryAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

EntryBatchAdminSession

public interface EntryAdminSession
extends OsidSession

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

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

The delete operations delete Entries. To unmap an Entry from the current Blog, the EntryBlogAssignmentSession should be used. These delete operations attempt to remove the Bid itself thus removing it from all known Blog catalogs.

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

the Blog associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

boolean canCreateEntries()

Tests if this user can create Entries. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating an Entry 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 Entry creation is not authorized, true otherwise

mandatory - This method must be implemented.

canCreateEntryWithRecordTypes

boolean canCreateEntryWithRecordTypes(Type[] entryRecordTypes)

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

Parameters:

entryRecordTypes - array of entry record types

Returns:

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

Throws:

NullArgumentException - entryRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getEntryFormForCreate

EntryForm getEntryFormForCreate(Type[] entryRecordTypes)
                                throws OperationFailedException,
                                       PermissionDeniedException

Gets the entry form for creating new entries. A new form should be requested for each create transaction.

Parameters:

entryRecordTypes - array of entry record types

Returns:

the entry form

Throws:

NullArgumentException - entryRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

boolean canUpdateEntries()

Tests if this user can update Entries. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating an Entry will result in a PERMISSION_DENIED.
