From 74b1b35402f6b9bbc09999a6224dfc04bc48b2a9 Mon Sep 17 00:00:00 2001 From: Colin Walters Date: Wed, 9 Mar 2005 17:09:11 +0000 Subject: 2005-03-09 Colin Walters * glib/dbus-gproxy.c (dbus_g_proxy_invoke): New method; calls to this are generated for client-side wrappers. Invokes a D-BUS method and returns reply values. * glib/dbus-binding-tool-glib.c (write_args_sig_for_direction): New function; writes signature string for argument direction. (write_args_for_direction): Change to pass input values directly instead of via address, and fix indentation. (generate_client_glue): Change to invoke dbus_g_proxy_invoke. Also make generated wrappers inlineable. * dbus/dbus-message.c (dbus_message_iter_get_fixed_array): Add note about using dbus_type_is_fixed. * dbus/dbus-marshal-basic.c (_dbus_type_is_fixed): Moved to dbus/dbus-signature.c as dbus_type_is_fixed. All callers updated. * dbus/dbus-signature.c (dbus_type_is_fixed): Moved here from dbus/dbus-marshal-basic.c:_dbus_type_is_fixed. * dbus/dbus-signature.h: Prototype. * glib/dbus-binding-tool-glib.c (compute_marshaller_name): Fix error printf code. * test/glib/test-dbus-glib.c (main): Be sure to clear error as appropriate instead of just freeing it. (main): Free returned strings using g_free. * test/glib/Makefile.am (test-service-glib-glue.h) (test-service-glib-bindings.h): Add dependency on dbus-binding-tool. * glib/dbus-gvalue.c (MAP_BASIC): Refactored from MAP_BASIC_INIT; simply maps a simple D-BUS type to GType. (dbus_dbus_type_to_gtype): Function which maps D-BUS type to GType. (dbus_gvalue_init): Just invoke dbus_dbus_type_to_gtype and initialize the value with it. (dbus_gvalue_binding_type_from_type): Unused, delete. (dbus_gvalue_demarshal): Switch to hardcoding demarshalling for various types instead of unmarshalling to value data directly. Remove can_convert boolean. (dbus_gvalue_marshal): Remove duplicate initialization; switch to returning directly instead of using can_convert boolean. (dbus_gvalue_store): New function; not related to D-BUS per-se. Stores a GValue in a pointer to a value of its corresponding C type. * glib/dbus-gvalue.h: Remove dbus_gvalue_binding_type_from_type, add dbus_gvalue_store. --- dbus/dbus-signature.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'dbus/dbus-signature.c') diff --git a/dbus/dbus-signature.c b/dbus/dbus-signature.c index 698c21ed..7cbae7c2 100644 --- a/dbus/dbus-signature.c +++ b/dbus/dbus-signature.c @@ -262,6 +262,36 @@ dbus_type_is_basic (int typecode) return !(typecode == DBUS_TYPE_INVALID || TYPE_IS_CONTAINER (typecode)); } +/** + * Tells you whether values of this type can change length if you set + * them to some other value.
