GLib.VariantType.prototype.next

function next(): GLib.VariantType {
    // Gjs wrapper for g_variant_type_next()
}
  

Determines the next item type of a tuple or dictionary entry type.

type must be the result of a previous call to GLib.VariantType.prototype.first or GLib.VariantType.prototype.next.

If called on the key type of a dictionary entry then this call returns the value type. If called on the value type of a dictionary entry then this call returns null.

For tuples, null is returned when type is the last item in a tuple.
