# FTReference

## Abstract

Used to store a reference from a node to another node.

## Discussion

In constrast to edges the implementation of this protocol simply refers to one node, the target node. This node my be either the source node (in case of an incoming reference) or the target node (in case of an outgoing reference).

## Methods

`-edgeId`
`-nodeId`

### edgeId

>     - (id <FTId>) edgeId;

method result
  id of related edge

### nodeId

>     - (id <FTId>) nodeId

method result
  id of referred node
