ZSet - node queue with a weight in the memory

methods

create: let zset = new ZSet({t1: {val: {val: 1}}})

add new item : zset.set('t2', {val: {val: 10}})

multiple add new item: zset.add({t3: {val: {val: 3}}})

increment weight item: zset.incr('t2', weight = 1)

search item: zset.search('val.val', callback)' callback example - (count) => count > 0 val.val - path

first item: zset.first()

last item: zset.first(true)

first and pop item: zset.firstPop()

del item: zset.del('t2')

get by key item: zset.byKey('t1')

restart weight zset.restart(default = 1)

clear zset zset.clear()

Links

only object values

setLink zset.setLink('t10.val', 10)

getLink zset.setLink(10)

delLink zset.delLink(10)

Install: npm i zset-node --save

Example use:

let ZSet = require('zset-node');
let zset = new ZSet({t1: {val: {val: 1}}});
zset.set('t2', {val: {val: 10}})
zset.incr('t2')
console.log(zset.first());
console.log(zset.search('val.val', (count) => count > 5));
zset.incr('t1', 5)
zset.incr('t2', -1)
console.log(zset.first());
zset.restart()
zset.byKey('t1')
zset.clear()
