OSID - osid.topology.batch.GraphBatchAdminSession Service Interface Definition

Interface	osid.topology.batch.GraphBatchAdminSession
Implements	`osid.topology.GraphAdminSession`
Used By	`osid.topology.batch.TopologyBatchManager`
Used By	`osid.topology.batch.TopologyBatchProxyManager`
Description	This session creates, updates, and deletes `Graphs` in bulk. 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 `Graph`, a `GraphForm` is requested using `getGraphFormsForCreate()` specifying the desired record `Types` or none if no record `Types` are needed. Each of the returned `GraphForms` 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 a `GraphForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `GraphForm` corresponds to an attempted transaction. The `GraphForms` returned from `getGraphFormsForCreate()` may be linked to the originating request through the peer `Ids` of the `GraphForm`. In the case where there may be duplicates, any `GraphForm` of the same peer `Ids` may be used for a create operation. Once a batch of `GraphForms` are submitted for create, a `CreateResponse` is returned for each `GraphForm`, although the ordering is not defined. Only errors that pertain to the entire create operation are returned from `createGraph()`, errors specific to an individual `GraphForm` are indicated in the corresponding `CreateResponse`. `CreateResponses` may be linked to the originating `GraphForm` through the `GraphForm` `Id`. For updates, `GraphForms` are requested to the `Graph` `Id` that is to be updated using `getGraphFormsForUpdate()` where the reference `Id` in the `GraphForm` may be used to link the request. Similarly, the `GraphForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `GraphForm` can only be used once for a successful update and cannot be reused. Once a batch of `GraphForms` are submitted for update, an `UpdateResponse` is returned for each `GraphForm`, although the ordering is not defined. Only errors that pertain to the entire update operation are returned from `updateGraph()`, errors specific to an individual `GraphForm` are indicated in the corresponding `UpdateResponse`. `UpdateResponses` may be linked to the originating `GraphForm` through the `GraphForm` `Id`. The delete operations delete `Graphs` in bulk. Bulk delete operations return the results in `DeleteResponses`.
Method	getGraphFormsForCreate
Description	Gets the graph forms for creating a bunch of new graph.
Parameters	`cardinal`	`number`	the number of forms to retrieve
Parameters	`osid.type.Type[]`	`graphRecordTypes`	array of graph record types to be included in each create operation or an empty list if none
Return	`osid.topology.batch.GraphBatchFormList`		the graph forms
Errors	NULL_ARGUMENT		`graphRecordTypes` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		unable to request forms with given record types
Compliance	`mandatory`		This method must be implemented.
Method	createGraphs
Description	Creates a new set of `Graphs`. This method returns an error if the entire operation fails. Otherwise, the status of an individual create operation is indicated in the `BatchCreateResponse`.
Parameters	`osid.topology.batch.GraphBatchFormList`	`graphForms`	the graph forms
Return	`osid.transaction.batch.CreateResponseList`		the create responses
Errors	NULL_ARGUMENT		`graphForms` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getGraphFormsForUpdate
Description	Gets the graph forms for updating an existing set of graphs. A new graph form should be requested for each update transaction.
Parameters	`osid.id.IdList`	`graphIds`	the `Ids` of the `Graphs`
Return	`osid.topology.batch.GraphBatchFormList`		the graph form
Errors	NOT_FOUND		a `graphId` is not found
	NULL_ARGUMENT		`graphIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	updateGraphs
Description	Updates existing graphs. This method returns an error if the entire operation fails. Otherwise, the status of an individual update operation is indicated in the `BatchCreateResponse`.
Parameters	`osid.topology.batch.GraphBatchFormList`	`graphForms`	the form containing the elements to be updated
Return	`osid.transaction.batch.UpdateResponseList`		the update responses
Errors	NULL_ARGUMENT		`graphForms` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	deleteAllGraphs
Description	Deletes all `Graphs`.
Return	`osid.transaction.batch.DeleteResponseList`		the delete responses
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	deleteGraphs
Description	Deletes graphs for the given `Ids`.
Parameters	`osid.id.IdList`	`graphIds`	the `Ids` of the graphs to delete
Return	`osid.transaction.batch.DeleteResponseList`		the delete responses
Errors	NULL_ARGUMENT		`graphIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	aliasGraphs
Description	Adds an `Id` to a `Graph` for the purpose of creating compatibility. The primary `Id` of the `Graph` is determined by the provider. The new `Id` is an alias to the primary `Id`. If the alias is a pointer to another graph, it is reassigned to the given graph `Id`.
Parameters	`osid.transaction.batch.AliasRequestList`	`aliasRequests`	the alias requests
Return	`osid.transaction.batch.AliasResponseList`		the alias responses
Errors	NULL_ARGUMENT		`aliasRequests` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
