Array Methods

[futurenets]

can array methods e.g. push, pop etc. be used with an array of objects?

Hello futurenets,

Please post a code example of what you're trying to do.

[futurenets]

creating an array of objects ....

var myArray = new Array();

for (x=0; x<20; x++) {
//create the object
var tmp = new Object;
//fill the object with data
tmp.priceHigh = high(-x);
tmp.priceLow = low(-x);
tmp.priceChange = (close(-x)-close(-(x+1)))/close(-(x+1));
//assign it to the array element
myArray[x] = tmp;
}


is it possible to re-dimension myArray? or use any of the standard array methods push, pop etc.

Hello Futurenets,

Yes, this will work and you can use the pop, push, shift and unshift methods to manipulate the size of the array. Here's the code snippet I just tested.

var myArray = new Array();

function main() {
    if (getCurrentBarIndex() != -1) return;
    for (x=0; x<20; x++) {
        //create the object
        var tmp = new Object;
        //fill the object with data
        tmp.priceHigh = high(-x);
        tmp.priceLow = low(-x);
        tmp.priceChange = (close(-x)-close(-(x+1)))/close(-(x+1));
        //assign it to the array element
        myArray[x] = tmp;
    }
    
    debugPrintln(myArray[0].priceHigh);
}
