KvpFrame Value Fetching | |
Value accessors. These all take a unix-style slash-separated path as an argument, and return the value stored at that location. If the object at the end of that path is not of the type that was asked for, then a NULL or a zero is returned. So, for example, asking for a string when the path stored an int will return a NULL. In some future date, this may be changed to a looser type system, such as perl's automatic re-typing (e.g. an integer value might be converted to a printed string representing that value). If any part of the path does not exist, then NULL or zero will be returned. The values returned for GUID, binary, GList, KvpFrame and string are "non-copying" -- the returned item is the actual item stored. Do not delete this item unless you take the required care to avoid possible bad pointer derefrences (i.e. core dumps). Also, be careful hanging on to those references if you are also storing at the same path names: the referenced item will be freed during the store.
That is, if you get a string value (or guid, binary or frame), and then store something else at that path, the string that you've gotten will be freed during the store (internally, by the set_*() routines), and you will be left hanging onto an invalid pointer. | |

KvpFrame KvpValue low-level storing routines. | |
You probably shouldn't be using these low-level routines All of the kvp_frame_set_slot_*() routines set the slot values "destructively", in that if there was an old value there, that old value is destroyed (and the memory freed). Thus, one should not hang on to value pointers, as these will get trashed if set_slot is called on the corresponding key.
If you want the old value, use kvp_frame_replace_slot(). | |
| KvpValue * | kvp_frame_replace_slot_nc (KvpFrame *frame, const gchar *slot, KvpValue *new_value) |
| void | kvp_frame_set_slot (KvpFrame *frame, const gchar *key, const KvpValue *value) |
| void | kvp_frame_set_slot_nc (KvpFrame *frame, const gchar *key, KvpValue *value) |
| void | kvp_frame_set_slot_path (KvpFrame *frame, const KvpValue *value, const gchar *first_key,...) |
| void | kvp_frame_set_slot_path_gslist (KvpFrame *frame, const KvpValue *value, GSList *key_path) |
KvpFrame KvpValue Low-Level Retrieval Routines | |
You probably shouldn't be using these low-level routines Returns the KvpValue in the given KvpFrame 'frame' that is associated with 'key'. If there is no key in the frame, NULL is returned. If the value associated with the key is NULL, NULL is returned.
Pointers passed as arguments into get_slot are the responsibility of the caller. Pointers returned by get_slot are owned by the kvp_frame. Make copies as needed. | |
| KvpValue * | kvp_frame_get_slot (const KvpFrame *frame, const gchar *key) |
| KvpValue * | kvp_frame_get_slot_path (KvpFrame *frame, const gchar *first_key,...) |

KvpValue List Convenience Functions | |

kvp_glist_compare() compares GLists of kvp_values (not to be confused with GLists of something else): it iterates over the list elements, performing a kvp_value_compare on each. | |
