Functions
Description
The prime purpose of a GValueArray is for it to be used as an
object property that holds an array of values. A GValueArray wraps
an array of GValue elements in order for it to be used as a boxed
type through G_TYPE_VALUE_ARRAY.
GValueArray is deprecated in favour of GArray since GLib 2.32. It
is possible to create a GArray that behaves like a GValueArray by
using the size of GValue as the element size, and by setting
g_value_unset() as the clear function using g_array_set_clear_func(),
for instance, the following code:
1 |
GValueArray *array = g_value_array_new (10); |
can be replaced by:
1 2 |
GArray *array = g_array_sized_new (FALSE, TRUE, sizeof (GValue), 10); g_array_set_clear_func (array, (GDestroyNotify) g_value_unset); |
Functions
g_value_array_get_nth ()
GValue * g_value_array_get_nth (GValueArray *value_array,guint index_);
g_value_array_get_nth has been deprecated since version 2.32 and should not be used in newly-written code.
Use g_array_index() instead.
Return a pointer to the value at index_
containd in value_array
.
g_value_array_new ()
GValueArray *
g_value_array_new (guint n_prealloced);
g_value_array_new has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_sized_new() instead.
Allocate and initialize a new GValueArray, optionally preserve space
for n_prealloced
elements. New arrays always contain 0 elements,
regardless of the value of n_prealloced
.
g_value_array_copy ()
GValueArray *
g_value_array_copy (const GValueArray *value_array);
g_value_array_copy has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_ref() instead.
Construct an exact copy of a GValueArray by duplicating all its contents.
g_value_array_free ()
void
g_value_array_free (GValueArray *value_array);
g_value_array_free has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_unref() instead.
Free a GValueArray including its contents.
[skip]
g_value_array_append ()
GValueArray * g_value_array_append (GValueArray *value_array,const GValue *value);
g_value_array_append has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_append_val() instead.
Insert a copy of value
as last element of value_array
. If value
is
NULL, an uninitialized value is appended.
Parameters
value_array |
GValueArray to add an element to |
|
value |
GValue to copy into GValueArray, or |
[nullable] |
g_value_array_prepend ()
GValueArray * g_value_array_prepend (GValueArray *value_array,const GValue *value);
g_value_array_prepend has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_prepend_val() instead.
Insert a copy of value
as first element of value_array
. If value
is
NULL, an uninitialized value is prepended.
Parameters
value_array |
GValueArray to add an element to |
|
value |
GValue to copy into GValueArray, or |
[nullable] |
g_value_array_insert ()
GValueArray * g_value_array_insert (GValueArray *value_array,guint index_,const GValue *value);
g_value_array_insert has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_insert_val() instead.
Insert a copy of value
at specified position into value_array
. If value
is NULL, an uninitialized value is inserted.
Parameters
value_array |
GValueArray to add an element to |
|
index_ |
insertion position, must be <= value_array->;n_values |
|
value |
GValue to copy into GValueArray, or |
[nullable] |
g_value_array_remove ()
GValueArray * g_value_array_remove (GValueArray *value_array,guint index_);
g_value_array_remove has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_remove_index() instead.
Remove the value at position index_
from value_array
.
Parameters
value_array |
GValueArray to remove an element from |
|
index_ |
position of value to remove, which must be less than
|
g_value_array_sort ()
GValueArray * g_value_array_sort (GValueArray *value_array,GCompareFunc compare_func);
g_value_array_sort has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_sort().
Sort value_array
using compare_func
to compare the elements according to
the semantics of GCompareFunc.
The current implementation uses the same sorting algorithm as standard
C qsort() function.
g_value_array_sort_with_data ()
GValueArray * g_value_array_sort_with_data (GValueArray *value_array,GCompareDataFunc compare_func,gpointer user_data);
g_value_array_sort_with_data has been deprecated since version 2.32 and should not be used in newly-written code.
Use GArray and g_array_sort_with_data().
Sort value_array
using compare_func
to compare the elements according
to the semantics of GCompareDataFunc.
The current implementation uses the same sorting algorithm as standard
C qsort() function.
[rename-to g_value_array_sort]
Parameters
value_array |
GValueArray to sort |
|
compare_func |
function to compare elements. |
[scope call] |
user_data |
extra data argument provided for |
[closure] |
Types and Values
struct GValueArray
struct GValueArray {
guint n_values;
