changed prototype of g_boxed_type_register_static() to contain an optional
Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org>
* gboxed.[hc]: changed prototype of g_boxed_type_register_static()
to contain an optional init function and a hint at whether the
boxed structure uses ref counting internally.
added g_value_set_boxed_take_ownership().
made G_TYPE_BOXED an abstract value type.
* genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
types.
* glib-genmarshal.c: argument type changes, preparation for third-party
arg specification.
* gobject.[hc]: cleaned up get/set property code.
added g_strdup_value_contents() to improve warnings.
* gparam.[hc]: added g_param_value_convert(), taking over responsibility
of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
validation alterations may be valid a part of the property setting
process.
* gparamspecs.[hc]: made value comparisons stable (for sort applications).
added GParamSpecValueArray, a param spec for value arrays and
GParamSpecClosure. nuked the value exchange functions and
GParamSpecCCallback.
* gtype.[hc]: catch unintialized usages of the type system with
g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
to flag types that introduce a value table, but can't be used for
g_value_init(). cleaned up reserved type ids.
* gvalue.[hc]: code cleanups and saner checking.
nuked the value exchange API. implemented value transformations, we
can't really "convert" values, rather transforms are an anylogy to
C casts, real conversions need a param spec for validation, which is
why g_param_value_convert() does real conversions now.
* gvaluearray.[hc]: new files that implement a GValueArray, a struct
that can hold inhomogeneous arrays of value (to that extend that it
also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
this is exposed to the type system as a boxed type.
* gvaluetransform.c: new file implementing most of the former value
exchange functions as single-sided transformations.
* gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
g_value_set_string_take_ownership().
* *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.
* *.[hc]: many fixes and cleanups.
* many warning improvements.
Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
into G_VALUE_LCOPY(), this needs proper documenting.
* gparam.c: fixed G_PARAM_USER_MASK.
* gtype.c (type_data_make_W):
(type_data_last_unref_Wm): fixed invalid memory freeing.
* gobject.c (g_object_last_unref): destroy signal handlers associated
with object, right before finalization.
* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
that don't actually support details.
* gobject.[hc]: got rid of property trailers. nuked GObject
properties "data" and the "signal" variants.
(g_object_connect): new convenience function to do multiple
signal connections at once.
(g_object_disconnect): likewise, for disconnections.
* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
as private (the latter got renamed from g_value_get_as_pointer()).
Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org>
* glib-object.h: add gvaluearray.h.
* gstring.[hc]: fixup naming of g_string_sprint*.
* gtypes.h: fixed GCompareDataFunc naming.
Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org>
* gobject/Makefile.am: shuffled rules to avoid excessive
rebuilds.
* gobject/gobject-sections.txt: updates.
* gobject/tmpl/*: bunch of updates, added another patch
from Eric Lemings <eric.b.lemings@lmco.com>.

To extend on our above string example: +<msgtext><programlisting> +{ + return value->data[0].v_pointer; +} +</programlisting></msgtext> +@collect_format: A string format describing how to collect the contents of + this value, bit-by-bit. Each character in the format represents + an argument to be collected, the characters themselves indicate + the type of the argument. Currently supported arguments are: +<msgtext><variablelist> + <varlistentry><term></term><listitem><para> + 'i' - Integers. passed as collect_values[].v_int. + </para></listitem></varlistentry> + <varlistentry><term></term><listitem><para> + 'l' - Longs. passed as collect_values[].v_long. + </para></listitem></varlistentry> + <varlistentry><term></term><listitem><para> + 'd' - Doubles. passed as collect_values[].v_double. + </para></listitem></varlistentry> + <varlistentry><term></term><listitem><para> + 'p' - Pointers. passed as collect_values[].v_pointer. + </para></listitem></varlistentry> +</variablelist></msgtext> + It should be noted, that for variable argument list construction, + ANSI C promotes every type smaller than an integer to an int, and + floats to doubles. So for collection of short int or char, 'i' + needs to be used, and for collection of floats 'd'. +@collect_value: The collect_value() function is responsible for converting the + values collected from a variable argument list into contents + suitable for storage in a GValue. This function should setup + @value similar to value_init(), e.g. for a string value that + does not allow NULL pointers, it needs to either spew an error, + or do an implicit conversion by storing an empty string. + The @value passed in to this function has a zero-filled data + array, so just like for @value_init it is guarranteed to not + contain any old contents that might need freeing. + @n_collect_values is exactly the string length of @collect_format, + and @collect_values is an array of unions #GTypeCValue with + length @n_collect_values, containing the collected values + according to @collect_format. + @collect_flags is an argument provided as a hint by the caller, + which may contain the flag #G_VALUE_NOCOPY_CONTENTS indicating, + that the collected value contents may be considered "static" + for the duration of the #@value lifetime. + Thus an extra copy of the contents stored in @collect_values is + not required for assignment to @value. + For our above string example, we continue with: +<msgtext><programlisting> +{ + if (!collect_values[0].v_pointer) + value->data[0].v_pointer = g_strdup (""); + else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) + { + value->data[0].v_pointer = collect_values[0].v_pointer; + /* keep a flag for the value_free() implementation to not free this string */ + value->data[1].v_uint = G_VALUE_NOCOPY_CONTENTS; + } + else + value->data[0].v_pointer = g_strdup (collect_values[0].v_pointer); + + return NULL; +} +</programlisting></msgtext> + It should be noted, that it is generally a bad idea to follow the + #G_VALUE_NOCOPY_CONTENTS hint for reference counted types. Due to + reentrancy requirements and reference count assertions performed + by the GSignal code, reference counts should always be incremented + for reference counted contents stored in the value->data array. + To deviate from our string example for a moment, and taking a look + at an exemplary implementation for collect_value() of #GObject: +<msgtext><programlisting> +{ + if (collect_values[0].v_pointer) + { + GObject *object = G_OBJECT (collect_values[0].v_pointer); + + /* never honour G_VALUE_NOCOPY_CONTENTS for ref-counted types */ + value->data[0].v_pointer = g_object_ref (object); + return NULL; + } + else + return g_strdup_printf ("Object passed as invalid NULL pointer"); +} +</programlisting></msgtext> + The reference count for valid objects is always incremented, + regardless of @collect_flags. For invalid objects, the example + returns a newly allocated string without altering @value. + Upon success, collect_value() needs to return NULL, if however + a malicious condition occoured, collect_value() may spew an + error by returning a newly allocated non-NULL string, giving + a suitable description of the error condition. + The calling code makes no assumptions about the @value + contents being valid upon error returns, @value + is simply thrown away without further freeing. As such, it is + a good idea to not allocate #GValue contents, prior to returning + an error, however, collect_values() is not obliged to return + a correctly setup @value for error returns, simply because + any non-NULL return is considered a fatal condition so further + program behaviour is undefined. +@lcopy_format: Format description of the arguments to collect for @lcopy_value, + analogous to @collect_format. Usually, @lcopy_format string consist + only of 'p's to provide lcopy_value() with pointers to storage locations. +@lcopy_value: This function is responsible for storing the @value contents into + arguments passed through a variable argument list which got + collected into @collect_values according to @lcopy_format. + @n_collect_values equals the string length of @lcopy_format, + and @collect_flags may contain #G_VALUE_NOCOPY_CONTENTS. + In contrast to collect_value(), lcopy_value() is obliged to + always properly support #G_VALUE_NOCOPY_CONTENTS. + Similar to collect_value() the function may prematurely abort + by returning a newly allocated string describing an error condition. + To complete the string example: +<msgtext><programlisting> +{ + gchar **string_p = collect_values[0].v_pointer; + + if (!string_p) + return g_strdup_printf ("string location passed as NULL"); + + if (collect_flags & G_VALUE_NOCOPY_CONTENTS) + *string_p = value->data[0].v_pointer; + else + *string_p = g_strdup (value->data[0].v_pointer); + +} +</programlisting></msgtext> + And an exemplary version of lcopy_value() for + reference-counted types: +<msgtext><programlisting> +{ + GObject **object_p = collect_values[0].v_pointer; + + if (!object_p) + return g_strdup_printf ("object location passed as NULL"); + if (!value->data[0].v_pointer) + *object_p = NULL; + else if (collect_flags & G_VALUE_NOCOPY_CONTENTS) /* always honour */ + *object_p = value->data[0].v_pointer; + else + *object_p = g_object_ref (value->data[0].v_pointer); + return NULL; +} +</programlisting></msgtext> diff --git a/docs/reference/gobject/tmpl/gobject-unused.sgml b/docs/reference/gobject/tmpl/gobject-unused.sgml index 8098c0650..1fe73b575 100644 --- a/docs/reference/gobject/tmpl/gobject-unused.sgml +++ b/docs/reference/gobject/tmpl/gobject-unused.sgml @@ -1,350 +1,36 @@ -<!-- ##### SECTION ./tmpl/closures.sgml:Long_Description ##### --> +<!-- ##### FUNCTION g_type_value_is_a ##### --> <para> - -</para> - - -<!-- ##### SECTION ./tmpl/closures.sgml:See_Also ##### --> -<para> - -</para> - - -<!-- ##### SECTION ./tmpl/closures.sgml:Short_Description ##### --> - - - -<!-- ##### SECTION ./tmpl/closures.sgml:Title ##### --> -Closures - - -<!-- ##### SECTION ./tmpl/gtypemodule.sgml.sgml:Long_Description ##### --> -<para> - -</para> - - -<!-- ##### SECTION ./tmpl/gtypemodule.sgml.sgml:See_Also ##### --> -<para> - -</para> - - -<!-- ##### SECTION ./tmpl/gtypemodule.sgml.sgml:Short_Description ##### --> - - - -<!-- ##### SECTION ./tmpl/gtypemodule.sgml.sgml:Title ##### --> -gtypemodule.sgml - - -<!-- ##### SECTION ./tmpl/signals.sgml:Long_Description ##### --> -<para> -The basic concept of the signal system is that of the <emphasis>emission</emphasis> -of a signal. -Signals are introduced per-type and are identified through strings. -Signals introduced for a parent type are availale in derived types as well, -so basically they are a per-type facility that is inherited. -A signal emission mainly involves invocation of a certain set of callbacks in -precisely defined manner.
