PHP eZContentObject::relationTypeMask方法代碼示例

    /**
     * Fetch the number of (reverse) related objects
     *
     * @param bool|int $version
     * @param int $attributeID
     *        This parameter only makes sense if $params[AllRelations] is unset,
     *        set to false, or matches eZContentObject::RELATION_ATTRIBUTE
     *        Possible values:
     *        - 0 or false:
     *          Count relations made with any attribute
     *        - >0
     *          Count relations made with attribute $attributeID
     * @param int|bool $reverseRelatedObjects
     *        Wether to count related objects (false) or reverse related
     *        objects (false)
     * @param array|bool $params
     *        Various params, as an associative array.
     *        Possible values:
     *        - AllRelations (bool|int)
     *          true: count ALL relations, object and attribute level
     *          false: only count object level relations
     *          other: bit mask of eZContentObject::RELATION_* constants
     *        - IgnoreVisibility (bool)
     *          If true, 'hidden' status will be ignored
     *
     * @return int The number of (reverse) related objects for the object
