Prerequisites

TpHandleRepoIface requires GObject.

Known Implementations

TpHandleRepoIface is implemented by TpDynamicHandleRepo and TpStaticHandleRepo.

Properties

  "handle-type"              guint                 : Read / Write / Construct Only

Description

Abstract interface of a repository for handles, supporting operations which include checking for validity, lookup by string value and lookup by numeric value. See TpDynamicHandleRepo and TpStaticHandleRepo for concrete implementations.

Details

TpHandleRepoIface

typedef struct _TpHandleRepoIface TpHandleRepoIface;

Dummy typedef representing any implementation of this interface.


TpHandleRepoIfaceClass

typedef struct _TpHandleRepoIfaceClass TpHandleRepoIfaceClass;

The class of a handle repository interface. The structure layout is only available within telepathy-glib, for the handle repository implementations' benefit.


tp_handle_is_valid ()

gboolean            tp_handle_is_valid                  (TpHandleRepoIface *self,

self :

A handle repository implementation

handle :

A handle of the type stored in the repository self

error :

Set to InvalidHandle if FALSE is returned

Returns :

TRUE if the handle is nonzero and is present in the repository, else FALSE

tp_handles_are_valid ()

gboolean            tp_handles_are_valid                (TpHandleRepoIface *self,

self :

A handle repository implementation

handles :

Array of TpHandle representing handles of the type stored in the repository self

allow_zero :

If TRUE, zero is treated like a valid handle

error :

Set to InvalidHandle if FALSE is returned

Returns :

TRUE if the handle is present in the repository, else FALSE

tp_handles_supported_and_valid ()

gboolean            tp_handles_supported_and_valid      (TpHandleRepoIface *repos[TP_NUM_HANDLE_TYPES],
                                                         TpHandleType handle_type,

                                                         GError **error);

Return TRUE if the given handle type is supported (i.e. repos[handle_type] is not NULL) and the given handles are all valid in that repository. If not, set error and return FALSE.

repos :

An array of possibly null pointers to handle repositories, indexed by handle type, where a null pointer means an unsupported handle type

handle_type :

The handle type

handles :

A GArray of guint representing handles of the given type

allow_zero :

If TRUE, zero is treated like a valid handle

error :

Used to return an error if FALSE is returned

Returns :

TRUE if the handle type is supported and the handles are all valid.

tp_handle_ref ()

Warning

tp_handle_ref is deprecated and should not be used in newly-written code. This is no-op so can be safely removed.

Do nothing. Since version 0.13.8, handles always last as long as the connection; previously, this function provided refcounting for handles.
