fl_value_append()

G_MODULE_EXPORT void fl_value_append	(	FlValue *	value,
		FlValue *	child
	)

fl_value_append: @value: an FlValue of type FL_VALUE_TYPE_LIST. @child: an FlValue.

Adds @child to the end of @value. Calling this with an FlValue that is not of type FL_VALUE_TYPE_LIST is a programming error.

fl_value_append_take()

fl_value_append_take: @value: an FlValue of type FL_VALUE_TYPE_LIST. @child: (transfer full): an FlValue.

Adds @child to the end of @value. Ownership of @child is taken by @value. Calling this with an FlValue that is not of type FL_VALUE_TYPE_LIST is a programming error.

fl_value_equal()

G_MODULE_EXPORT bool fl_value_equal	(	FlValue *	a,
		FlValue *	b
	)

fl_value_equal: : an FlValue. : an FlValue.

Compares two FlValue to see if they are equivalent. Two values are considered equivalent if they are of the same type and their data is the same including any child values. For values of type FL_VALUE_TYPE_MAP the order of the values does not matter.

Returns: TRUE if both values are equivalent.

fl_value_new_list()

G_MODULE_EXPORT FlValue* fl_value_new_list

fl_value_new_list:

Creates an ordered list. Children can be added to the list using fl_value_append(). The children are accessed using fl_value_get_length() and fl_value_get_list_value(). The equivalent Dart type is a List<dynamic>.

The following example shows a simple list of values:

|[ g_autoptr(FlValue) value = fl_value_new_list (); fl_value_append_take (value, fl_value_new_string ("one"); fl_value_append_take (value, fl_value_new_int (2); fl_value_append_take (value, fl_value_new_double (3.0); ]|

This value can be decoded using:

|[ g_assert (fl_value_get_type (value) == FL_VALUE_TYPE_LIST); for (size_t i = 0; i < fl_value_get_length (value); i++) { FlValue *child = fl_value_get_list_value (value, i); process_value (child); } ]|

Returns: a new FlValue.

fl_value_new_map:

Creates an ordered associative array. Children can be added to the map using fl_value_set(), fl_value_set_take(), fl_value_set_string(), fl_value_set_string_take(). The children are accessed using fl_value_get_length(), fl_value_get_map_key(), fl_value_get_map_value(), fl_value_lookup() and fl_value_lookup_string(). The equivalent Dart type is a Map<dynamic>.

The following example shows how to create a map of values keyed by strings:

|[ g_autoptr(FlValue) value = fl_value_new_map (); fl_value_set_string_take (value, "name", fl_value_new_string ("Gandalf")); fl_value_set_string_take (value, "occupation", fl_value_new_string ("Wizard")); fl_value_set_string_take (value, "age", fl_value_new_int (2019)); ]|

This value can be decoded using: |[ g_assert (fl_value_get_type (value) == FL_VALUE_TYPE_MAP); FlValue *name = fl_value_lookup_string (value, "name"); g_assert (fl_value_get_type (name) == FL_VALUE_TYPE_STRING); FlValue *age = fl_value_lookup_string (value, "age"); g_assert (fl_value_get_type (age) == FL_VALUE_TYPE_INT); g_message ("Next customer is %s (%d years old)", fl_value_get_string (name), fl_value_get_int (age)); ]|
