OSID - osid.lexicon.PressAdminSession Service Interface Definition

Interface	osid.lexicon.PressAdminSession
Implements	`osid.OsidSession`
Implemented By	`osid.lexicon.batch.PressBatchAdminSession`
Used By	`osid.lexicon.LexiconManager`
Used By	`osid.lexicon.LexiconProxyManager`
Description	This session creates, updates, and deletes `Presses` . 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 `Press` , a `PressForm` is requested using `getPressFormForCreate()` specifying the desired record `Types` or none if no record `Types` are needed. The returned `PressForm` 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 `PressForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `PressForm` corresponds to an attempted transidiom. For updates, `PressForms` are requested to the `Press` `Id` that is to be updated using `getPressFormForUpdate()` . Similarly, the `PressForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `PressForm` can only be used once for a successful update and cannot be reused. The delete operations delete `Presses` . This session includes an `Id` aliasing mechanism to assign an external `Id` to an internally assigned Id.

Compliance	`mandatory`		This method must be implemented.
Method	canCreatePressWithRecordTypes
Description	Tests if this user can create a single `Press` using the desired record types.

Providing an empty array tests if a `Press` can be created with no records.
