A dynamic handle repository will accept arbitrary handles, which can be created and destroyed at runtime.
The "handle-type" property must be set at construction time; the "normalize-function" property may be set to perform validation and normalization on handle ID strings.
Most connection managers will use this for all supported handle types
except TP_HANDLE_TYPE_CONTACT_LIST.
typedef struct _TpDynamicHandleRepo TpDynamicHandleRepo;
A dynamic handle repository. The contents of the struct are private.
typedef struct _TpDynamicHandleRepoClass TpDynamicHandleRepoClass;
The class of a dynamic handle repository. The contents of the struct are private.
TpHandle tp_dynamic_handle_repo_lookup_exact (TpHandleRepoIface *irepo, const char *id);
Look up a name in the repository, returning the corresponding handle if it is present in the repository, without creating a new reference.
Unlike tp_handle_lookup() this function does not perform any normalization;
it just looks for the literal string you requested. This can be useful to
call from normalization callbacks (for instance, Gabble's contacts
repository uses it to see whether we already know that a JID belongs
to a multi-user chat room member).

The handle repository |
|
The name to be looked up |
Returns : |
the handle corresponding to the given ID, or 0 if not present |
TpHandleRepoIface* tp_dynamic_handle_repo_new (TpHandleType handle_type, TpDynamicHandleRepoNormalizeFunc normalize_func, gpointer default_normalize_context);
|
The handle type |
|
The function to be used to normalize and validate handles,
or NULL to accept all handles as-is
|
|
The context pointer to be passed to the
normalize_func if a NULL context is passed to tp_handle_lookup() and
tp_handle_ensure(); this may itself be NULL
|
Returns : |
a new dynamic handle repository |
gchar* (*TpDynamicHandleRepoNormalizeFunc) (TpHandleRepoIface *repo, const gchar *id, gpointer context, GError **error);
Signature of the normalization function optionally used by TpDynamicHandleRepo instances.
|
The repository on which tp_handle_lookup() or tp_handle_ensure()
was called
|
|
The name to be normalized |
|
Arbitrary context passed to tp_handle_lookup() or
tp_handle_ensure()
|
|
Used to raise the Telepathy error InvalidHandle with an appropriate message if NULL is returned |
Returns : |
a normalized version of id (to be freed with g_free by the
caller), or NULL if id is not valid for this repository
|
"default-normalize-context" property"default-normalize-context" gpointer : Read / Write / Construct Only
The default context given to the normalize-function if NULL is passed as context to the ensure or lookup function, e.g. when RequestHandleis called via D-Bus. The default is NULL.
