|
* This class provides the metadata for the MaxMind DB file. |

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. |
