Module: mathsync/skeleton

Methods

<static> newResolver(updater, remote, serialize, deserialize)

Creates a new resolver.

Parameters:

Name	Type	Description
updater	Summary~SummaryBatchUpdater	the updater giving local items.
remote	Summarizer	summarizer producing summaires of the remote side.
serialize	Serial~Serialize	the item serializer.
deserialize	Serial~Deserialize	the item deserializer.

Source:

• skeleton.js, line 147

Example

Items from an array.

var remote = ...
var items = [{ from: 1, to: 2 }, { from: 2, to: 5}];
function updater(item, done) {
 items.forEach(item);
 done();
}
function serialize(item) {
 return new Int32Array([item.from, item.to]).buffer;
}
function deserialize(buffer) {
 var arr = new Int32Array(buffer);
 return { from: arr[0], to: arr[1] };
}
var resolver = require('mathsync/skeleton').newResolver(updater, remote, serialize, deserialize);

<static> newSummarizer(updater, serialize, digester, selector)

Creates a new summarizer.

The summarizer first counts the items as it builds an IBF, and then if the IBF is larger than the total number of items restart building a full content summary. This prevents infinite loops over the level in case of issue, like the same item added twice.

Parameters:

Name	Type	Argument	Description
updater	Summary~SummaryBatchUpdater		the updater giving local items.
serialize	Serial~Serialize		the item serializer.
digester	Digest~Digester	<optional>	the digester to use, defaults to SHA-1.
selector	BucketSelector~Selector	<optional>	how to place items in IBF buckets, uses 3 buckets by default.
