class Metadata in Smart IP 6.2

This class provides the metadata for the MaxMind DB file.

@property integer nodeCount This is an unsigned 32-bit integer indicating the number of nodes in the search tree.

@property integer 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 integer 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 integer binaryFormatMajorVersion This is an unsigned 16-bit integer indicating the major version number for the database's binary format.

@property integer binaryFormatMinorVersion This is an unsigned 16-bit integer indicating the minor version number for the database's binary format.

@property integer 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.
