Description

A GckEnumerator can be used to enumerate through PKCS#11 objects. It will automatically create sessions as necessary.

Use gck_modules_enumerate_objects() or gck_modules_enumerate_uri() to create an enumerator. To get the objects use gck_enumerator_next() or gck_enumerator_next_async() functions.

Functions

gck_enumerator_next ()

GckObject *
gck_enumerator_next (GckEnumerator *self,
                     GCancellable *cancellable,
                     GError **error);

Get the next object in the enumerator, or NULL if there are no more objects.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

Parameters

self

The enumerator

 

cancellable

A GCancellable or NULL

 

error

A location to store an error on failure

 

Returns

The next object, which must be released using g_object_unref, or NULL.

gck_enumerator_next_async ()

void
gck_enumerator_next_async (GckEnumerator *self,
                           gint max_objects,
                           GCancellable *cancellable,
                           GAsyncReadyCallback callback,
                           gpointer user_data);

Get the next set of objects from the enumerator. This operation completes asynchronously.The maximum number of objects can be specified with max_objects . If -1 is specified, then all the remaining objects will be enumerated.

Parameters

self

An enumerator

 

max_objects

The maximum number of objects to get

 

cancellable

A GCancellable or NULL

 

callback

Called when the result is ready

 

user_data

Data to pass to the callback

 

gck_enumerator_next_finish ()

GList *
gck_enumerator_next_finish (GckEnumerator *self,
                            GAsyncResult *result,
                            GError **error);

Complete an operation to enumerate next objects.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

Parameters

self

An enumerator

 

result

The result passed to the callback

 

error

A location to raise an error on failure.

 

Returns

The list of objects, which should be freed with gck_list_unref_free().

[element-type Gck.Object][transfer full]


gck_enumerator_next_n ()

GList *
gck_enumerator_next_n (GckEnumerator *self,
                       gint max_objects,
                       GCancellable *cancellable,
                       GError **error);

Get the next set of objects from the enumerator. The maximum number of objects can be specified with max_objects . If -1 is specified, then all the remaining objects will be returned.

NULL is also returned if the function fails. Use the error to determine whether a failure occurred or not.

Parameters

self

An enumerator

 

max_objects

The maximum amount of objects to enumerate

 

cancellable

A GCancellable or NULL

 

error

A location to store an error on failure

 

Returns

A list of objects, which should be freed using gck_list_unref_free().

[transfer full][element-type Gck.Object]


gck_enumerator_get_interaction ()

GTlsInteraction *
gck_enumerator_get_interaction (GckEnumerator *self);

Get the interaction used when a pin is needed

Parameters

self

the enumerator

 

Returns

the interaction or NULL.

[transfer full][allow-none]


gck_enumerator_set_interaction ()

void
gck_enumerator_set_interaction (GckEnumerator *self,
                                GTlsInteraction *interaction);

Set the interaction used when a pin is needed

Parameters

self

the enumerator

 

interaction

the interaction or NULL.

[allow-none]

gck_enumerator_get_object_type ()

GType
gck_enumerator_get_object_type (GckEnumerator *self);

Get the type of objects created by this enumerator. The type will always either be GckObject or derived from it.

Parameters

self

an enumerator

 

Returns

the type of objects created


gck_enumerator_set_object_type ()

void
gck_enumerator_set_object_type (GckEnumerator *self,
                                GType object_type);

Set the type of objects to be created by this enumerator. The type must always be either GckObject or derived from it.

If the GckObjectCache interface is implemented on the derived class and the default_types class field is set, then the enumerator will retrieve attributes for each object.

[skip]

Parameters

self

an enumerator

 

object_type

the type of objects to create

 

gck_enumerator_set_object_type_full ()

void
gck_enumerator_set_object_type_full (GckEnumerator *self,
                                     GType object_type,
                                     const gulong *attr_types,
                                     gint attr_count);

Set the type of objects to be created by this enumerator. The type must always be either GckObject or derived from it.

If attr_types and attr_count are non-NULL and non-zero respectively, then the GckObjectCache interface is expected to be implemented on the derived class, then the enumerator will retrieve attributes for each object.

gck_enumerator_get_chained ()

GckEnumerator *
gck_enumerator_get_chained (GckEnumerator *self);

Get the enumerator that will be run after all objects from this one are seen.

Parameters

self

the enumerator

 

Returns

the chained enumerator or NULL.
