MultiDimensional

Create and manage self aware multi-dimensional arrays of anything. Use this module to:

• Make multi-dimensional array instances with as many dimensions as you'd like.
• Initialize the array with any type of value or object.
• Set and Get positions within the array to any value or object.
• Do all this with a simple and scalable interface.

Basic Usage

Install

npm install --save multidimensional

Basic Usage

var MultiDimensional = require('multidimensional')

Initialize a New Instance

To create a new MultiDimensional, create a new instance and pass in the dimensional sizes as an array. By default all values will initialize as null:

// create a 3x3 array
var twodimensional = new MultiDimensional([3, 3])

// create a 3x3x4 array
var threedimensional = new MultiDimensional([3, 3, 4])

// create a 4x3x4x2 array
var fourdimensional = new MultiDimensional([4, 3, 4, 2])

// etc...

Set Initial Values

If you want to create a new instance with initial values, you can pass in an initial value for all positions:

// create a 3x4 array with all positions set to 0
var twodimensional = new MultiDimensional([3, 4], 0)

// create a 3x3x4 array with all positions set to 'Default String'
var threedimensionalAsStrings = new MultiDimensional([3, 3, 4], 'Default String')

Or pass in a callback to return a value or object to be put in position. The callback takes the position and the multidimensional instance it will be added to.

// create a 3x3x4 array with all positions set to a unique Cell object.
var threedimensional = new MultiDimensional([3, 3, 4], function(position, multidimensional) {
    return new Cell(position, multidimensional.dimensions)
})

function Cell(position, overallDimensions) {
    this.position = position
    this.overallDimensions = overallDimensions
}

Get Position Values

IMPORTANT: Position indexes start at [0, 0, 0]. So if you created an array of size 3x4x5 ([3, 4, 5]), the highest index will be [2, 3, 4].

threedimensional.position([2, 2, 2])

Set Position Values

threedimensional.position([2, 2, 2], 'New Value')
