The bad worst-case +behavior is a small price to pay, given that treaps are much simpler +to implement. + +API +=== + +The trp API generates a data structure and functions to handle a +large growing set of objects stored in a pool. + +The caller: + +. Specifies parameters for the generated functions with the + trp_gen(static, foo_, ...) macro. + +. Allocates a `struct trp_root` variable and sets it to {~0}. + +. Adds new nodes to the set using `foo_insert`. + +. Can find a specific item in the set using `foo_search`. + +. Can iterate over items in the set using `foo_first` and `foo_next`. + +. Can remove an item from the set using `foo_remove`. + +Example: + +---- +struct ex_node { + const char *s; + struct trp_node ex_link; +}; +static struct trp_root ex_base = {~0}; +obj_pool_gen(ex, struct ex_node, 4096); +trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp) +struct ex_node *item; + +item = ex_pointer(ex_alloc(1)); +item->s = "hello"; +ex_insert(&ex_base, item); +item = ex_pointer(ex_alloc(1)); +item->s = "goodbye"; +ex_insert(&ex_base, item); +for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item)) + printf("%s\n", item->s); +---- + +Functions +--------- + +trp_gen(attr, foo_, node_type, link_field, pool, cmp):: + + Generate a type-specific treap implementation. ++ +. The storage class for generated functions will be 'attr' (e.g., `static`). +. Generated function names are prefixed with 'foo_' (e.g., `treap_`). +. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`). + This type must be a struct with at least one `struct trp_node` field + to point to its children. +. The field used to access child nodes will be 'link_field'. +. All treap nodes must lie in the 'pool' object pool. +. Treap nodes must be totally ordered by the 'cmp' relation, with the + following prototype: ++ +int (*cmp)(node_type \*a, node_type \*b) ++ +and returning a value less than, equal to, or greater than zero +according to the result of comparison. + +void foo_insert(struct trp_root *treap, node_type \*node):: + + Insert node into treap. If inserted multiple times, + a node will appear in the treap multiple times. + +void foo_remove(struct trp_root *treap, node_type \*node):: + + Remove node from treap. Caller must ensure node is + present in treap before using this function. + +node_type *foo_search(struct trp_root \*treap, node_type \*key):: + + Search for a node that matches key. If no match is found, + result is NULL. + +node_type *foo_nsearch(struct trp_root \*treap, node_type \*key):: + + Like `foo_search`, but if if the key is missing return what + would be key's successor, were key in treap (NULL if no + successor). + +node_type *foo_first(struct trp_root \*treap):: + + Find the first item from the treap, in sorted order. + +node_type *foo_next(struct trp_root \*treap, node_type \*node):: + + Find the next item. |
