ngraph.frombinary

Deserialize an ngraph.graph from binary format.

Install

Install with npm:

$ npm install --save ngraph.frombinary

Usage

var load = require('ngraph.frombinary');

API

load

Load a ngraph.graph that was previously saved using ngraph.tobinary. This expects that the meta.json file created with ngraph.tobinary is in the folder. See the parse method below when labels and links are already in memory.

Example

var graph = load(new Graph({uniqueLinkIds: false}), {cwd: '.'});
console.log(graph.getNodesCount());
//=> 4
console.log(graph.getLinksCount());
//=> 3

Params

• graph {Object}: ngraph.graph instance to load the binary files into.
• options {Object}: Options to determine where the graph is loaded from.
• options.cwd {String}: Directory where the files are located. Defaults to ..
• options.labels {String}: Name of the labels file. Defaults to labels.json.
• options.links {String}: Name of the links file. Defaults to meta.json.
• options.meta {String}: Name of the meta file. Defaults to links.bin.
• returns {Object}: graph instance that was passed in after loading the binary files.

parse

Parse function that can be used directly to parse a links buffer and populate a ngraph.graph graph with nodes and links. This is useful when the labels (node names) array and the links buffer have already been loaded into memory.

Example

var labels = ['a', 'b', 'c', 'd'];
var links = fs.readFileSync('links.bin');
// links contains a binary buffer that looks like: `-1 2 3 -4 2`
var graph = load.parse(new Graph({uniqueLinkIds: false}), labels, links);
console.log(graph.getNodesCount());
//=> 4
console.log(graph.getLinksCount());
//=> 3

Params

• graph {Object}: ngraph.graph instance to load nodes and links onto.
• labels {Array}: Array of labels used to lookup node names for the graph.
• links {Buffer}: Binary buffer represented links to deserialize onto the graph.
• returns {Object}: graph instance populated with nodes and links.
