public function Permissions::getValueOptions

Child classes should be used to override this function and set the 'value options', unless 'options callback' is defined as a valid function or static public method to generate these values.

This can use a guard to be used to reduce database hits as much as possible.

Return value

Return the stored values in $this->value_options if someone expects it.
