kList Class Reference
kApi/Data

## Description

Represents a doubly-linked list.

The kList class represents a doubly-linked list of objects or values. The kList constructor accepts a kType value that determines the type of items that will be stored in the list. The list will automatically grow as new items are added or inserted.

kStatus ListExample()
{
kList list = kNULL;
k32s values[] = { 1, 2, 3, 5, 7, 9 };
kSize i;
kListItem it = kNULL; //list iterator
kTry
{
//create a list that can store 32-bit integers
kTest(kList_Construct(&list, kTypeOf(k32s), 0, kNULL));
//add some initial items to the list
for (i = 0; i < kCountOf(values); ++i)
{
kTest(kList_AddT(list, &values[i], kNULL);
}
//print some information about the list and its items
printf("Item type: %s\n", kType_Name(kList_ItemType(list)));
printf("Count: %u\n", (k32u) kList_Count(list));
it = kList_First(list);
while (!kIsNull(it))
{
//get an item from the list
k32s value = kList_AsT(list, it, k32s);
it = kList_Next(list, it);
}
}
kFinally
{
kObject_Destroy(list);
kEndFinally();
}
return kOK;
}

For lists that contain objects (e.g. kImage) as opposed to values (e.g. k32s), the objects are not automatically destroyed when the list is destroyed. To recursively destroy both the list and the list items, use kObject_Dispose.

kList supports the kObject_Clone, kObject_Dispose, and kObject_Size methods.

kList supports the kdat6 serialization protocol.
