Description

A heap queue of pointers.

Details

TpHeap

typedef struct _TpHeap TpHeap;

Structure representing the heap queue. All fields are private.


tp_heap_new ()

TpHeap *            tp_heap_new                         (GCompareFunc comparator,
                                                         GDestroyNotify destructor);

comparator :

Comparator by which to order the pointers in the heap

destructor :

Function to call on the pointers when the heap is destroyed or cleared, or NULL if this is not needed

Returns :

A new, empty heap queue.

tp_heap_destroy ()

void                tp_heap_destroy                     (TpHeap *heap);

Destroy a TpHeap. The destructor, if any, is called on all items.

heap :

The heap queue

tp_heap_clear ()

void                tp_heap_clear                       (TpHeap *heap);

Remove all items from a TpHeap. The destructor, if any, is called on all items.

heap :

The heap queue

tp_heap_add ()

void                tp_heap_add                         (TpHeap *heap,
                                                         gpointer element);

Add element to the heap queue, maintaining correct order.

heap :

The heap queue

element :

An element

tp_heap_remove ()

void                tp_heap_remove                      (TpHeap *heap,
                                                         gpointer element);

Remove element from heap, if it's present. The destructor, if any, is not called.

heap :

The heap queue

element :

An element in the heap

tp_heap_peek_first ()

gpointer            tp_heap_peek_first                  (TpHeap *heap);

heap :

The heap queue

Returns :

The first item in the queue, or NULL if the queue is empty

tp_heap_extract_first ()

gpointer            tp_heap_extract_first               (TpHeap *heap);

Remove and return the first element in the queue. The destructor, if any, is not called.

heap :

The heap queue

Returns :

the removed element

tp_heap_size ()

guint               tp_heap_size                        (TpHeap *heap);

heap :

The heap queue

Returns :

The number of items in heap
