/**
 * This class provides the metadata for the MaxMind DB file.
 *
 * @property int    $nodeCount                This is an unsigned 32-bit
 *                                            integer indicating the number of
 *                                            nodes in the search tree.
 * @property int    $recordSize               This is an unsigned 16-bit
 *                                            integer. It indicates the number
 *                                            of bits in a record in the search
 *                                            tree. Note that each node
 *                                            consists of two records.
 * @property int    $ipVersion                This is an unsigned 16-bit
 *                                            integer which is always 4 or 6.
 *                                            It indicates whether the database
 *                                            contains IPv4 or IPv6 address
 *                                            data.
 * @property string $databaseType             This is a string that indicates
 *                                            the structure of each data record
 *                                            associated with an IP address.
 *                                            The actual definition of these
 *                                            structures is left up to the
 *                                            database creator.
 * @property array  $languages                An array of strings, each of
 *                                            which is a language code. A given
 *                                            record may contain data items
 *                                            that have been localized to some
 *                                            or all of these languages. This
 *                                            may be undefined.
 * @property int    $binaryFormatMajorVersion This is an unsigned 16-bit
 *                                            integer indicating the major
 *                                            version number for the database's
 *                                            binary format.
 * @property int    $binaryFormatMinorVersion This is an unsigned 16-bit
 *                                            integer indicating the minor
 *                                            version number for the database's
 *                                            binary format.
 * @property int    $buildEpoch               This is an unsigned 64-bit
 *                                            integer that contains the
 *                                            database build timestamp as a
 *                                            Unix epoch value.
 * @property array  $description              This key will always point to a
 *                                            map (associative array). The keys
 *                                            of that map will be language
 *                                            codes, and the values will be a
 *                                            description in that language as a
 *                                            UTF-8 string. May be undefined
 *                                            for some databases.
