class jala.ListRenderer.ArrayList

A simple wrapper around an array to use in conjunction with jala.ListRenderer. This wrapper can either handle complete arrays or subsections of an array. In the latter case the wrapper needs offset and total size information as argument to mimick a complete array.
Defined in ListRenderer.js

Field Detail

length

Number length

The length of this ArrayList instance.

offset

Number offset

The offset of this ArrayList instance. This might be > zero for ArrayList instances wrapping just a subsection, that is mimicking a bigger list.

The size of this ArrayList instance
