OE dbx file format : 'tree'

The tree stores int4 values. In the dbx files the int4 values are pointers to indexed info objects. The nodes of the tree are the tree nodes. The tree node is the basic part of the tree. Each node object is 0x27c bytes long. 0x18 bytes for the header and 0x264 bytes for the body.

( 8)int4stored values in the child tree (3)
The body of a tree node contains (6) entries.
Each entry consists of 3 int4 values :
