pyxis v1.1.1

pyxis.ts

An associative container for TypeScript

1) Associative: values are referenced by key and not by position.

2) Unique keys: each key in container is unique.

3) Ordered: all keys are kept in order.

4) Mapped: each entry associates a key to a mapped value.

1) empty : test whether container is empty or not.

2) clear : empties container

3) size : returns number of entries in container.

4) locate(key) : locates value of entry by key.

5) insert(key, value) : inserts a unique key into container in sorted order.

6) remove(key) : removes key and its associated value from the container.

7) enum : enumerate the keys in the container

Install:

npm install pyxis

Compile:

tsc file-name.ts --target es5

Run:

node file-name.js

import Container from './node_modules/pyxis/index'

// create new container
let container = new Container()

// insert key-value pairs into container
// key and value can be of any type
container.insert(1, "foo")
container.insert(2, "bar")
container.insert(3, "baz")

// enumerate each key in the container
container.enum().forEach(el => {
    console.log(el.key, el.value)
    /*
        1 'foo'
        2 'bar'
        3 'baz'
    */
})

// find item in container with key of "3"
console.log(container.locate(3)) // baz

// get the size of the container
console.log(container.size()) // 3

// remove item from container with key of "1"
container.remove(1)

console.log(container.size()) // 2

// test if container is empty
if(!container.empty()) console.log('contains stuff') // contains stuff

// clear all contents of container
container.clear()

console.log(container.size()) // 0
