addLink batch function

[toqueteos]

Is there any way of adding a list of links? Right now one must call addLink N times.

Instead of:

graph.addLink(0, 1);
graph.addLink(0, 2);
graph.addLink(1, 3);
graph.addLink(2, 1);
graph.addLink(2, 4);
graph.addLink(3, 2);
graph.addLink(4, 0);

This:

graph.addLinkBatch([[0, 1], [0, 2], [1, 3], [2, 1], [2, 4], [3, 2], [4, 0]])

@toqueteos I see how batch operations could be useful, but I'm trying to keep core graph object API as small as possible. It exposes two primitives to implement all sort of batch updates in helper methods: graph.beginUpdate() and graph.endUpdate().

Here is an example:

function addLinkBatch(graph, linksArray) {
  // enter into batch modification block. Nothing will be updated on UI
  // or layout until we call endUpdate();
  graph.beginUpdate();
  for (var i = 0; i < linksArray.length; ++i) {
    var linkPair = linksArray[i];
    graph.addLink(linkPair[0], linkPair[1]);
  }
  // Now let the world know the graph was changed.
  graph.endUpdate(); 
}

@anvaka Well, maybe I issued this too fast; just using that for loop of yours should be fine.

Of course not updating UI each time if lots of adds are expected is a nice thing, so thanks for your proposed solution 👍.

Feel free to close this whenever you want.
