|
|
* 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.
