DIFFUSION_TOPIC_VIEW_T * diffusion_topic_view_dup

(

const DIFFUSION_TOPIC_VIEW_T *

topic_view

)

Returns a memory allocated copy of a DIFFUSION_TOPIC_VIEW_T.

diffusion_topic_view_free should be called on this pointer when no longer needed.

Parameters

topic_view

the topic_view to be copied.

Returns

a copy of a DIFFUSION_TOPIC_VIEW_T. NULL, if event is NULL.

diffusion_topic_view_free()

void diffusion_topic_view_free

(

DIFFUSION_TOPIC_VIEW_T *

topic_view

)

Free a memory allocated DIFFUSION_TOPIC_VIEW_T

Parameters

topic_view

the DIFFUSION_TOPIC_VIEW_T to be freed.

diffusion_topic_view_get_name()

char * diffusion_topic_view_get_name

(

const DIFFUSION_TOPIC_VIEW_T *

topic_view

)

Return a memory allocated copy of the topic view's name.

free should be called on this pointer when no longer needed.

Parameters

topic_view

the topic view

Returns

the topic view's name.

diffusion_topic_view_get_roles()

SET_T * diffusion_topic_view_get_roles

(

const DIFFUSION_TOPIC_VIEW_T *

topic_view

)

Return a memory allocated SET_T of the topic view's roles.

set_free should be called on this pointer when no longer needed.

Parameters

topic_view

the topic view

Returns

the topic view's roles used when evaluating permissions.

diffusion_topic_view_get_specification()

char * diffusion_topic_view_get_specification

(

const DIFFUSION_TOPIC_VIEW_T *

topic_view

)

Return a memory allocated copy of the topic view's specification.

free should be called on this pointer when no longer needed.

Parameters

topic_view

the topic view

Returns

the topic view's specification.

diffusion_topic_views_create_topic_view()

bool diffusion_topic_views_create_topic_view	(	SESSION_T *	session,
		const DIFFUSION_CREATE_TOPIC_VIEW_PARAMS_T	params,
		DIFFUSION_API_ERROR *	api_error )

Create a new named topic view.

If a view with the same name already exists the new view will replace the existing view.

Parameters

session	The current session. If NULL, this function returns immediately.
params	Parameters defining the diffusion_topic_views_create_topic_view request and callbacks.
api_error	Populated on API error. Can be NULL.

Returns

true if the operation was successful. False, otherwise. In this case, if a non-NULL api_error pointer has been provided, this will be populated with the error information and should be freed with diffusion_api_error_free.

diffusion_topic_views_get_topic_view()

bool diffusion_topic_views_get_topic_view	(	SESSION_T *	session,
		const DIFFUSION_GET_TOPIC_VIEW_PARAMS_T	params,
		DIFFUSION_API_ERROR *	api_error )

Get a named Topic View.

If the named view does not exist the handler on_topic_view will complete successfully with a NULL topic_view.

Parameters

session	The current session. If NULL, this function returns immediately.
params	Parameters defining the diffusion_topic_views_get_topic_view request and callbacks.
api_error	Populated on API error. Can be NULL.

Returns

true if the operation was successful. False, otherwise. In this case, if a non-NULL api_error pointer has been provided, this will be populated with the error information and should be freed with diffusion_api_error_free.

diffusion_topic_views_list_topic_views()

bool diffusion_topic_views_list_topic_views	(	SESSION_T *	session,
		const DIFFUSION_TOPIC_VIEWS_LIST_PARAMS_T	params,
		DIFFUSION_API_ERROR *	api_error )

List all the topic views that have been created.

Parameters

session	The current session. If NULL, this function returns immediately.
params	Parameters defining the diffusion_topic_views_list_topic_views request and callbacks.
api_error	Populated on API error. Can be NULL.

Returns

true if the operation was successful. False, otherwise. In this case, if a non-NULL api_error pointer has been provided, this will be populated with the error information and should be freed with diffusion_api_error_free.

diffusion_topic_views_remove_topic_view()

bool diffusion_topic_views_remove_topic_view	(	SESSION_T *	session,
		const DIFFUSION_REMOVE_TOPIC_VIEW_PARAMS_T	params,
		DIFFUSION_API_ERROR *	api_error )

Remove a named topic view if it exists.

If the named view does not exist the handler on_topic_view_removed will complete successfully.

Parameters

session	The current session. If NULL, this function returns immediately.
params	Parameters defining the diffusion_topic_views_remove_topic_view request and callbacks.
api_error	Populated on API error. Can be NULL.

Returns

true if the operation was successful. False, otherwise. In this case, if a non-NULL api_error pointer has been provided, this will be populated with the error information and should be freed with diffusion_api_error_free.
