<para>
-
+The #GValue structure is basically a variable container that consists
+of a type identifier and a specific value of that type.
+The type identifier within a #GValue structure always determines the
+type of the associated value.
+To create a undefined #GValue structure, simply create a zero-filled
+#GValue structure. To intialize the #GValue, use the g_value_init()
+function. A #GValue cannot be used until it is initialized.
+The basic type operations (such as freeing and copying) are determined
+by the #GTypeValueTable associated with the type ID stored in the #GValue.
+Other #GValue operations (such as converting values between types) are
+provided by this interface.
</para>
<!-- ##### SECTION See_Also ##### -->

</para>
-@value_type1:
-@value_type2:
-@func:
-
+@value_init: Default initialize @values contents by poking values
+ directly into the value->data array. The data array of
+ the #GValue passed into this function was zero-filled
+ with memset, so no care has to be taken to free any
+ old contents. E.g. for the implementation of a string
+ value that may never be NULL, the implementation might
+ look like:
+<msgtext><programlisting>
+{
+ value->data[0].v_pointer = g_strdup ("");
+}
+</programlisting></msgtext>
+@value_free: Free any old contents that might be left in the
+ data array of the passed in @value. No resources may
+ remain allocated through the #GValue contents after
+ this function returns. E.g. for our above string type:
+<msgtext><programlisting>
+{
+ /* only free strings without a specific flag for static storage */
+ if (!(value->data[1].v_uint & G_VALUE_NOCOPY_CONTENTS))
+ g_free (value->data[0].v_pointer);
+}
+</programlisting></msgtext>
+@value_copy: @dest_value is a #GValue with zero-filled data section
+ and @src_value is a properly setup #GValue of same or
+ derived type.
+ The purpose of this function is to copy the contents of
+ @src_value into @dest_value in a way, that even after
+ @src_value has been freed, the contents of @dest_value
+ remain valid. String type example:
+<msgtext><programlisting>
+{
+ dest_value->data[0].v_pointer = g_strdup (src_value->data[0].v_pointer);
+}
+</programlisting></msgtext>
+@value_peek_pointer: If the value contents fit into a pointer, such as objects
+ or strings, return this pointer, so the caller can peek at
+ the current contents. 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>

+</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;
+}

-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. There are two main categories of such callbacks,
-per-object
- <footnote><para> Although signals can deal with any kind of type, i'm
- referring to those types as "object types" in the following, simply
- because that is the context most users will encounter signals in.
- </para></footnote>
-ones and user provided ones.
-The per-object callbacks are most often referred to as "object method
-handler" or "default (signal) handler", while user provided callbacks are
-usually just called "signal handler".
-The object method handler is provided at signal creation time (this most
-frequently happens at the end of an object class' creation), while user
-provided handlers are frequently connected and disconnected to/from a certain
-signal on certain object instances.
-</para>
-<para>
-A signal emission consists of five stages, unless prematurely stopped:
-<variablelist>
- <varlistentry><term></term><listitem><para>
- 1 - Invocation of the object method handler for %G_SIGNAL_RUN_FIRST signals
- </para></listitem></varlistentry>
- <varlistentry><term></term><listitem><para>
- 2 - Invocation of normal user-provided signal handlers (<emphasis>after</emphasis> flag %FALSE)

- 3 - Invocation of the object method handler for %G_SIGNAL_RUN_LAST signals

- <varlistentry><term></term><listitem><para>
- 5 - Invocation of the object method handler for %G_SIGNAL_RUN_CLEANUP signals
- </para></listitem></varlistentry>
-</variablelist>
-The user provided signal handlers are called in the order they were
-connected in.
-All handlers may prematurely stop a signal emission, and any number of
-handlers may be connected, disconnected, blocked or unblocked during
-a signal emission.
-There are certain criteria for skipping user handlers in stages 2 and 4
-of a signal emission.
-First, user handlers may be <emphasis>blocked</emphasis>, blocked handlers are omitted
-during callback invocation, to return from the "blocked" state, a
-handler has to get unblocked exactly the same amount of times
-it has been blocked before.
-Second, upon emission of a %G_SIGNAL_DETAILED signal, an additional
-"detail" argument passed in to g_signal_emit() has to match the detail
-argument of the signal handler currently subject to invocation.
-Specification of no detail argument for signal handlers (omission of the
-detail part of the signal specification upon connection) serves as a
-wildcard and matches any detail argument passed in to emission.

- * gparamspecs.c (g_param_spec_interface): add a new param spec to
- handle interfaces.
+ * 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.

+
+ * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS

+ 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()).
