From 979308aa7f42073e309737cd18da58731437bf3a Mon Sep 17 00:00:00 2001 From: Přemysl Janouch Date: Tue, 26 Oct 2010 16:18:15 +0200 Subject: Manage LdLibrary children in a GSList. The previous method of containment, that is using GHashTable, did not list children in any particular order. Also names of children were duplicated. One copy has been stored as a hash table index and another was present in the child itself. --- src/ld-library.c | 68 +++++++++++++++++++++++++++++++++++++++++++++------- src/ld-library.h | 7 +++--- src/ld-window-main.c | 19 ++++++++------- 3 files changed, 75 insertions(+), 19 deletions(-) diff --git a/src/ld-library.c b/src/ld-library.c index 891c594..7f96b96 100644 --- a/src/ld-library.c +++ b/src/ld-library.c @@ -29,11 +29,13 @@ /* * LdLibraryPrivate: - * @script_state: State of the scripting language. + * @lua: State of the scripting language. + * @children: Child objects of the library. */ struct _LdLibraryPrivate { LdLua *lua; + GSList *children; }; G_DEFINE_TYPE (LdLibrary, ld_library, G_TYPE_OBJECT); @@ -85,9 +87,7 @@ ld_library_init (LdLibrary *self) (self, LD_TYPE_LIBRARY, LdLibraryPrivate); self->priv->lua = ld_lua_new (); - - self->categories = g_hash_table_new_full (g_str_hash, g_str_equal, - (GDestroyNotify) g_free, (GDestroyNotify) g_object_unref); + self->priv->children = NULL; } static void @@ -98,7 +98,9 @@ ld_library_finalize (GObject *gobject) self = LD_LIBRARY (gobject); g_object_unref (self->priv->lua); - g_hash_table_destroy (self->categories); + + g_slist_foreach (self->priv->children, (GFunc) g_object_unref, NULL); + g_slist_free (self->priv->children); /* Chain up to the parent class. */ G_OBJECT_CLASS (ld_library_parent_class)->finalize (gobject); @@ -288,8 +290,7 @@ ld_library_load_cb (const gchar *base, const gchar *filename, gpointer userdata) cat = load_category (data->self, filename, base); if (cat) - g_hash_table_insert (data->self->categories, - g_strdup (ld_symbol_category_get_name (cat)), cat); + ld_library_insert_child (data->self, G_OBJECT (cat), -1); data->changed = TRUE; return TRUE; @@ -306,9 +307,60 @@ ld_library_clear (LdLibrary *self) { g_return_if_fail (LD_IS_LIBRARY (self)); - g_hash_table_remove_all (self->categories); + g_slist_foreach (self->priv->children, (GFunc) g_object_unref, NULL); + g_slist_free (self->priv->children); + self->priv->children = NULL; g_signal_emit (self, LD_LIBRARY_GET_CLASS (self)->changed_signal, 0); } +/** + * ld_library_insert_child: + * @self: An #LdLibrary object. + * @child: The child to be inserted. + * @pos: The position at which the child will be inserted. + * Negative values will append to the end of list. + * + * Insert a child into the library. + */ +void +ld_library_insert_child (LdLibrary *self, GObject *child, gint pos) +{ + g_return_if_fail (LD_IS_LIBRARY (self)); + g_return_if_fail (G_IS_OBJECT (child)); + + g_object_ref (child); + self->priv->children = g_slist_insert (self->priv->children, child, pos); +} + +/** + * ld_library_remove_child: + * @self: An #LdLibrary object. + * @child: The child to be removed. + * + * Removes a child from the library. + */ +void +ld_library_remove_child (LdLibrary *self, GObject *child) +{ + g_return_if_fail (LD_IS_LIBRARY (self)); + g_return_if_fail (G_IS_OBJECT (child)); + + g_object_unref (child); + self->priv->children = g_slist_remove (self->priv->children, child); +} + +/** + * ld_library_get_children: + * @self: An #LdLibrary object. + * + * Return value: The internal list of children.
