composite.js

This JavaScript code defines a function named composite which is responsible for aggregating multiple graphs into a single graph. The function takes an array of concepts as its parameter, where each concept is an object containing a name and a graph. (ChatGPT 3.5)

// aggregate multiple graphs into a single graph import {Graph} from './graph.js' const uniq = (value, index, self) => self.indexOf(value) === index export function composite(concepts) { const merged = {nids:[]} const comp = new Graph() for (const concept of concepts) { const {name,graph} = concept merge(comp,graph,name) } return {graph:comp, merged} function merge(comp,incr,source) { function mergeprops(into,from) { const keys = Object.keys(into) .concat(Object.keys(from)) .filter(uniq) for (const key of keys) { if (into[key]) { // if (from[key] && into[key] != from[key]) { // window.result.innerHTML += // `<div style="font-size:small; padding:4px; background-color:#fee; border-radius:4px; border:1px solid #aaa;"> // conflict for "${key}" property<br> // choosing "${into[key]}" over "${from[key]}"</div>` // } } else { if(from[key]) { into[key] = from[key] } } } } const nids = {} // incr => comp incr.nodes.forEach((node,id) => { const match = comp.nodes.find(each => each.type == node.type && each.props.name == node.props.name) if(match) { // window.result.innerHTML += `Same <b>${match.type}</b> ${match.props.name}<br>` nids[id] = comp.nodes.findIndex(node => node === match) merged.nids.push(nids[id]) mergeprops(match.props, node.props) } else { nids[id] = comp.addNode(node.type,node.props) } }) incr.rels.forEach(rel => { const match = comp.rels.find(each => each.type == rel.type && each.from == nids[rel.from] && each.to == nids[rel.to] ) if(match) { // window.result.innerHTML += `Same // <b>${comp.nodes[match.from].type}</b> ${comp.nodes[match.from].props.name} // <b>${match.type}</b> ▷ // ${comp.nodes[match.to].type} ${comp.nodes[match.to].props.name}<br>` mergeprops(match.props, rel.props) } else { rel.props.source = source comp.addRel(rel.type, nids[rel.from], nids[rel.to], rel.props) } }) } }
