IObjectInteraction
Handles object interactions via directed relations (arcs).
Encodings
- SID : {uint64 set | uint64 id} → uint128
- Node : {uint64 data | uint32 _ | uint32 grant | uint64 set | uint64 id} → uint256
- Arc : {uint64 data | uint64 rel | uint64 set | uint64 id} → uint256
Functions
relate
Links a tail object to a head object through a relation
function relate(uint256 tail, uint64 rel, uint256 head) external;
Parameters
| Name | Type | Description |
|---|---|---|
tail | uint256 | Encoded tail node |
rel | uint64 | Relation ID |
head | uint256 | Encoded head node |
unrelate
Unlinks a tail object from a head object
function unrelate(uint256 tail, uint64 rel, uint256 head) external;
Parameters
| Name | Type | Description |
|---|---|---|
tail | uint256 | Encoded tail node |
rel | uint64 | Relation ID |
head | uint256 | Encoded head node |
Events
