From 8b7c7f5a753b43cec10f72b274bb1d70c253652b Mon Sep 17 00:00:00 2001 From: reduz Date: Sun, 8 May 2022 10:09:19 +0200 Subject: Add a new HashMap implementation Adds a new, cleaned up, HashMap implementation. * Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing). * Keeps elements in a double linked list for simpler, ordered, iteration. * Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much for performance vs keeping the key, but helps replace old code). * Uses a more modern C++ iterator API, deprecates the old one. * Supports custom allocator (in case there is a wish to use a paged one). This class aims to unify all the associative template usage and replace it by this one: * Map<> (whereas key order does not matter, which is 99% of cases) * HashMap<> * OrderedHashMap<> * OAHashMap<> --- core/io/resource.cpp | 17 ++++++----------- 1 file changed, 6 insertions(+), 11 deletions(-) (limited to 'core/io/resource.cpp') diff --git a/core/io/resource.cpp b/core/io/resource.cpp index e6535c67a4..e81382b72e 100644 --- a/core/io/resource.cpp +++ b/core/io/resource.cpp @@ -478,10 +478,8 @@ void ResourceCache::clear() { if (resources.size()) { ERR_PRINT("Resources still in use at exit (run with --verbose for details)."); if (OS::get_singleton()->is_stdout_verbose()) { - const String *K = nullptr; - while ((K = resources.next(K))) { - Resource *r = resources[*K]; - print_line(vformat("Resource still in use: %s (%s)", *K, r->get_class())); + for (const KeyValue &E : resources) { + print_line(vformat("Resource still in use: %s (%s)", E.key, E.value->get_class())); } } } @@ -516,10 +514,8 @@ Resource *ResourceCache::get(const String &p_path) { void ResourceCache::get_cached_resources(List> *p_resources) { lock.read_lock(); - const String *K = nullptr; - while ((K = resources.next(K))) { - Resource *r = resources[*K]; - p_resources->push_back(Ref(r)); + for (KeyValue &E : resources) { + p_resources->push_back(Ref(E.value)); } lock.read_unlock(); } @@ -544,9 +540,8 @@ void ResourceCache::dump(const char *p_file, bool p_short) { ERR_FAIL_COND_MSG(f.is_null(), "Cannot create file at path '" + String::utf8(p_file) + "'."); } - const String *K = nullptr; - while ((K = resources.next(K))) { - Resource *r = resources[*K]; + for (KeyValue &E : resources) { + Resource *r = E.value; if (!type_count.has(r->get_class())) { type_count[r->get_class()] = 0; -- cgit v1.2.3
