OSID - osid.blogging.EntryAdminSession Service Interface Definition

Interface	osid.blogging.EntryAdminSession
Implements	`osid.OsidSession`
Description	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.
Method	getBlogId
Description	Gets the `Blog` `Id` associated with this session.
Return	`osid.id.Id`		the `Blog Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getBlog
Description	Gets the `Blog` associated with this session.
Return	`osid.blogging.Blog`		the `Blog` associated with this session
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canCreateEntries
Description	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.
Return	`boolean`		`false` if `Entry` creation is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canCreateEntryWithRecordTypes
Description	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	`osid.type.Type[]`	`entryRecordTypes`	array of entry record types
Return	`boolean`		`true` if `Entry` creation using the specified `Types` is supported, `false` otherwise
Errors	NULL_ARGUMENT		`entryRecordTypes` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getEntryFormForCreate
Description	Gets the entry form for creating new entries. A new form should be requested for each create transaction.
Parameters	`osid.type.Type[]`	`entryRecordTypes`	array of entry record types
Return	`osid.blogging.EntryForm`		the entry form
Errors	NULL_ARGUMENT		`entryRecordTypes` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		unable to get form for requested record types
Compliance	`mandatory`		This method must be implemented.
Method	createEntry
Description	Creates a new `Entry.`
Parameters	`osid.blogging.EntryForm`	`entryForm`	the form for this `Entry`
Return	`osid.blogging.Entry`		the new `Entry`

	UNSUPPORTED		`entryForm` did not originate from `getEntryFormForCreate()`
Compliance	`mandatory`		This method must be implemented.
Method	canUpdateEntries
Description	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.` This is intended as a hint to an application that may opt not to offer update operations to an unauthorized user.
Return	`boolean`		`false` if `Entry` modification is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	getEntryFormForUpdate
Description	Gets the entry form for updating an existing entry. A new entry form should be requested for each update transaction.

	UNSUPPORTED		`entryForm` did not originate from `getEntryFormForUpdate()`
Compliance	`mandatory`		This method must be implemented.
Method	canDeleteEntries
Description	Tests if this user can delete `Entries.` A return of true does not guarantee successful authorization. A return of false indicates that it is known deleting an `Entry` will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer delete operations to an unauthorized user.
Return	`boolean`		`false` if `Entry` deletion is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
