time-ordered-set
Efficiently maintain a set of nodes ordered by the time they were added to the set
npm install time-ordered-set
Usage
var set = require('time-ordered-set')
var s = set()
// add 3 nodes
s.add({
hello: 'world'
})
var node = s.add({
hello: 'welt'
})
s.add({
hello: 'verden'
})
// re-add the 2nd one
s.add(node)
console.log(s.toArray().map(node => node.hello)) // ['world', 'verden', 'welt']
API
var s = set()
Create a new set
node = s.add(node)
Add a new node to the set. Will add the properties node.next and node.prev to the node.
Re-adding the same node will move to the latest node.
node = s.remove(node)
Remove a node. Will set node.next and node.prev to null.
bool = s.has(node)
Check if a node has been added.
var array = s.toArray(maxCount)
Get an ordered array out of all the nodes, ordered from oldest to newest. Set maxCount if you only want to get a subset.
s.oldest
Property containing the oldest node.
s.latest
Property containing the newest node.
s.length
Property containing how many nodes are in the set.
