Typedef Documentation

typedef struct SHI_Engine SHI_Engine

A SHI_Engine object is the initial point of interaction between an application and a DRM Engine.

It encapsulates the state of a DRM Engine, provides access to internal data structures, and provides information about transactions that it is performing on behalf of the application.

Function Documentation

SHI_PUBLIC_API SHI_Result SHI_Engine_Create	(	const SHI_EngineConfig *	config,
		SHI_Engine **	engine
	)

Creates a SHI_Engine object.

This object must be destroyed by calling SHI_Engine_Destroy when it is no longer needed.

The configuration passed to this method specifies configuration flags and the listener that will receive the event callbacks.

Parameters

config	Pointer to the configuration for the engine.
engine	Address of a SHI_Engine pointer that will be set to refer to the SHI_Engine object created.

SHI_PUBLIC_API SHI_Result SHI_Engine_CreateLicense	(	SHI_Engine *	self,
		SHI_License **	license
	)

Creates a new SHI_License object managed by this engine.

That is, the SHI_License object is local to this engine, and cannot be used independently of it. The SHI_License object must be destroyed by calling SHI_License_Destroy when it is no longer needed, prior to destroying the engine.

Parameters

self	The SHI_Engine that will manage the license.
license	Address of a SHI_License pointer that will be set to refer to the SHI_License created.

SHI_PUBLIC_API SHI_Result SHI_Engine_DeleteObject	(	SHI_Engine *	self,

This object must be a link or a node, and cannot be the personality node.

Parameters

self	A SHI_Engine pointer.
object_id	The ID of the Octopus object.

SHI_PUBLIC_API SHI_Result SHI_Engine_Destroy ( SHI_Engine * self )

SHI_PUBLIC_API SHI_Boolean SHI_Engine_IsPersonalized ( SHI_Engine * self )

Indicates whether or not this engine has been personalized.

Parameters

self	The SHI_Engine that is checked.

Returns: SHI_TRUE if the engine is already personalized, or SHI_FALSE if it has not yet been personalized.

SHI_PUBLIC_API SHI_Result SHI_Engine_Personalize	(	SHI_Engine *	self,
		const char *	token,
		SHI_Size	token_size,
		const void *	cookie
	)

Requests that this engine engage in the personalization process.

This method performs the personalization synchronously and does not return until it is complete. The progress and results are signaled by callbacks to the engine's event listener. Note: The personalization process is represented by a transaction of SHI_TransactionType SHI_TRANSACTION_TYPE_PERSONALIZATION.

The 'token' parameter can be NULL in which case the token_size is ignored, and a default personalization token is utilized. Such a default personalization token can be selected at build time through the Sushi Configuration procedure. See the Sushi Deployment Guide for details.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for performing personalization is specified in the final callback indicating the end of the transaction.

If this engine is already personalized, this method returns SHI_ERROR_ENGINE_ALREADY_PERSONALIZED.

Parameters

self	The SHI_Engine to be personalized.
token	Pointer to the service token data, or NULL.
token_size	Size in bytes of the service token data.
cookie	An arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of the personalization.

		const char *	token,
		SHI_Size	token_size,
		const void *	cookie
	)

Requests that this engine process a service token, such as a Broadband Action Token.

This method performs all operations synchronously and does not return until completing processing of the service token. The progress and status information are signaled by callbacks to the engine's event listener.

The return value for this method indicates simply whether the method call succeeded. The success or failure result of the transaction for processing the service token is specified in the final callback indicating the end of the transaction.

Parameters

self	The SHI_Engine that will process the token.
token	Pointer to the service token data.
token_size	Size in bytes of the service token data.
cookie	An arbitrary pointer that will be passed back to the engine listener in callbacks regarding any transaction related to the processing of this token.

		const char *	token,
		SHI_Size	token_size,
		const void *	cookie,
		SHI_RegistrationDataManager *	registration_data_manager
	)

Use this API instead of SHI_Engine_ProcessServiceToken if you want to overwrite the default behavior for saving and loading nodes and links during registration.

Removes expired data stored in Sushi's database.

After this method is called, this engine instance may not be used again. You must destroy this engine and create a new instance. Engine methods may return SHI_ERROR_ENGINE_POST_VACUUM after this call. Note: the engine must be destroyed even if SHI_Engine_VacuumData returns an error code.

Parameters

self	A SHI_Engine pointer.
vacuum_options	The type of data to be vacuumed (permanently deleted), as specified in SHI_ENGINE_VACUUM_FLAG_XXX flags.
