Basic Usage

For most use-cases you'll want to extend AbstractIterator (the iter-over abstract iterator class). This abstract class implements such methods as #forEachRemaining(callback) and automagically implements the [Symbol.iterator] method so that you don't have to!

The only methods you have to implement are:

public hasNext(): boolean { ... }
public next(): E | undefined { ... }

So for example, an inline implementation would look something like:

import { AbstractIterator } from "iter-over";

class MyCounter extends AbstractIterator<number> {

	private val: number = 0;
	
	public hasNext(): boolean {
		
		return (this.val <= 9);
		
	}
	
	public next(): number {
		
		return this.val++;
		
	}
	
}

Once you've done that, you can freely use the iterator as such:

let counter: MyCounter = new MyCounter();

for (let counterVal of counter) console.log(counterVal);

// ...console logs 0 through 9.
