From 38b70d0dc5c39e6278bf30c67e1e12f7ac8c1fa0 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Tue, 27 Nov 2018 01:09:06 -0800 Subject: libpad: add ix2_reset() This basically amounts to adding a pad_reset() wrapper. Also incorporated resets into the test, while fixing a stupid bug there. --- src/ix2.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'src/ix2.c') diff --git a/src/ix2.c b/src/ix2.c index 3569ae6..9a8fd02 100644 --- a/src/ix2.c +++ b/src/ix2.c @@ -150,7 +150,9 @@ static void init_node(ix2_node_t *node, bb2f_t *aabb) assert(node); assert(aabb); + node->children = NULL; INIT_LIST_HEAD(&node->objects); + node->n_objects = 0; node->center.x = aabb->min.x; node->center.y = aabb->min.y; @@ -450,6 +452,23 @@ fail_ix2: } +/* Reset the index ix2 to its state as-returned by ix2_new() + * + * Note this doesn't free memory, it just discards the index while keeping all + * the memory around in the caches for efficient reuse. + */ +void ix2_reset(ix2_t *ix2) +{ + assert(ix2); + + pad_reset(ix2->node_pad); + pad_reset(ix2->ref_pad); + pad_reset(ix2->object_pad); + + init_node(&ix2->root, &ix2->aabb); +} + + /* Free the index ix2 and everything associated with it */ /* Note the external objects which have been indexed are not freed */ void ix2_free(ix2_t *ix2) -- cgit v1.2.3
