6: * This class provides the metadata for the MaxMind DB file.
7: *
8: * @property int nodeCount This is an unsigned 32-bit integer indicating
9: * the number of nodes in the search tree.
10: * @property int recordSize This is an unsigned 16-bit integer. It
11: * indicates the number of bits in a record in the search tree. Note that each
12: * node consists of two records.
13: * @property int ipVersion This is an unsigned 16-bit integer which is
14: * always 4 or 6. It indicates whether the database contains IPv4 or IPv6
15: * address data.
16: * @property string databaseType This is a string that indicates the structure
17: * of each data record associated with an IP address. The actual definition of
18: * these structures is left up to the database creator.
19: * @property array languages An array of strings, each of which is a language
20: * code. A given record may contain data items that have been localized to
21: * some or all of these languages. This may be undefined.
22: * @property int binaryFormatMajorVersion This is an unsigned 16-bit
23: * integer indicating the major version number for the database's binary
24: * format.
25: * @property int binaryFormatMinorVersion This is an unsigned 16-bit
26: * integer indicating the minor version number for the database's binary format.
27: * @property int buildEpoch This is an unsigned 64-bit integer that
28: * contains the database build timestamp as a Unix epoch value.
29: * @property array description This key will always point to a map
30: * (associative array). The keys of that map will be language codes, and the
31: * values will be a description in that language as a UTF-8 string. May be
32: * undefined for some databases.
