Batches

A batch accumulates and packages multiple operations (method calls) on objects. The batch is then run in a single operation.

Because a batch can significantly improve performance, consider creating a batch when application logic lends itself to running a series of operations that can be completed without application intervention between batch items. For example, an application might create a Folder object, create a Document object, and create a DynamicReferentialContainmentRelationship object for filing a document in a folder, all associated with a single UpdatingBatch object. The Content Engine server updates the objects in the same order as they appear in the list that is associated with the UpdatingBatch object. Batch processing is suitable for retrieving property values for multiple objects by using a RetrievingBatch object. Properties to be fetched are specified independently for each object, and all of the property fetches are run in a single round trip to the server.

Each operation included in a batch is referenced as a BatchItemHandle instance. A batch is a subclass of the Batch abstract class, and contains the list of BatchItemHandle instances. Whether a batch is a transactional operation depends on its type:
