Value arrays

A container structure to maintain an array of generic values

<para>
|
|
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.
