void xmmsv_coll_add_operand ( xmmsv_coll_t coll,
xmmsv_coll_t op 
)

Add the operand to the given collection.

Parameters:
collThe collection to add the operand to.
opThe operand to add.

Definition at line 195 of file coll.c.

Referenced by bind_all_references().

void xmmsv_coll_attribute_foreach ( xmmsv_coll_t coll,
xmmsv_coll_attribute_foreach_func  func,
void *  user_data 
)

Iterate over all key/value-pair of the collection attributes.

Calls specified function for each key/value-pair of the attribute list.

void function (const char *key, const char *value, void *user_data);

Parameters:
collthe xmmsv_coll_t.
funcfunction that is called for each key/value-pair
user_dataextra data passed to func

Definition at line 538 of file coll.c.

int xmmsv_coll_attribute_get ( xmmsv_coll_t coll,
const char *  key,
char **  value 
)

Retrieve the value of the attribute of the given collection.

The return value is 1 if the attribute was found and 0 otherwise. The value of the attribute is owned by the collection and must not be freed by the caller.

Parameters:
collThe collection to retrieve the attribute from.
keyThe name of the attribute.
valueThe value of the attribute if found (owned by the collection).
Returns:
1 if the attribute was found, 0 otherwise

int xmmsv_coll_attribute_remove ( xmmsv_coll_t coll,
const char *  key 
)

Remove an attribute from the given collection.

The return value indicated whether the attribute was found (and removed)

Parameters:
collThe collection to remove the attribute from.
keyThe name of the attribute to remove.
Returns:
1 upon success, 0 otherwise

Definition at line 481 of file coll.c.

void xmmsv_coll_attribute_set ( xmmsv_coll_t coll,
const char *  key,
const char *  value 
)

Set an attribute in the given collection.

Parameters:
collThe collection in which to set the attribute.
keyThe name of the attribute to set.
valueThe value of the attribute.

const int32_t* xmmsv_coll_get_idlist ( xmmsv_coll_t coll)

Return the list of ids stored in the collection.

The list is owned by the collection. Note that this must not be confused with the content of the collection, which must be queried using xmmsc_coll_query_ids!

Also note that this function is deprecated (use xmmsv_coll_idlist_get instead) and that changes to the returned array will be ignored. The array is also not updated when the idlist is changed using the supplied functions. Additionally every call to this function allocates a new array, so calling it repetitively will be a performance penalty.

Parameters:
collThe collection to consider.
Returns:
The 0-terminated list of ids.

Definition at line 390 of file coll.c.

Return the type of the collection.

Parameters:
collThe collection to consider.
Returns:
The xmmsv_coll_type_t of the collection, or -1 if invalid.

Definition at line 367 of file coll.c.

int xmmsv_coll_idlist_append ( xmmsv_coll_t coll,
int  id 
)

Append a value to the idlist.

Parameters:
collThe collection to update.  
idThe id to append to the idlist.
Returns:
TRUE on success, false otherwise.

Definition at line 252 of file coll.c.

Referenced by xmms_playlist_add_entry_unlocked().

Empties the idlist.

Parameters:
collThe collection to update.
Returns:
TRUE on success, false otherwise.

Definition at line 309 of file coll.c.

Return the list of ids stored in the collection.

This function does not increase the refcount of the list, the reference is still owned by the collection.

Note that this must not be confused with the content of the collection, which must be queried using xmmsc_coll_query_ids!

Parameters:
collThe collection to consider.
Returns:
The 0-terminated list of ids.

Definition at line 429 of file coll.c.
