Class: McGeLongArray

2d.McGeLongArray

McGeLongArray represents an array container for a set of integer values.

Description

This class is used to store and manipulate a set of integer data, commonly used for numerical caching within CAD Set of object IDs, color channel data, and other scenes. It provides common capabilities such as append, read, modify, and traverse.

Example

import { McGeLongArray } from "mxcad";

const values = new McGeLongArray();
values.append(10);
values.append(20);
values.append(30);

Console. log (values. length())//Get the length of the array;
Console. log (values. at (1))//Get the value of the element with index 1;

Example

import { McGeLongArray } from "mxcad"

  const array1 = new McGeLongArray();
  const array2 = new McGeLongArray();
  array2.append(10);
  array2.append(20);
