Adjacency
Represents a constraint on the acceptable number of objects by kind in a relation. A maximum of 16 adjacencies can be specified per relation.
Adjacencies are typically specified in a row, with kinds ordered in ascending order.
struct Adjacency {
uint16 degs;
uint48 kind;
}
Properties
| Name | Type | Description |
|---|---|---|
degs | uint16 | Encodes minimum and maximum degree constraints. minDeg = (degs & 0x8000) >> 15, maxDeg = degs & 0x7FFF |
kind | uint48 | Kind ID of the related object. 0 = any other kind, 0xFFFFFFFFFFFF = total, [1, 2^48 - 2] = specific kind ID |
