constructor

• new McGeLongArray(imp?)

构造函数。

Example

import { McGeLongArray } from "mxcad"

 // 创建一个新的 McGeLongArray 实例
 const myArray = new McGeLongArray();

 // 通过传入一个对象初始化 McGeLongArray
 const initialValues = { data: [1, 2, 3, 4] };
 const myArray2 = new McGeLongArray(initialValues);

Parameters

Name	Type	Description
imp?	object	内部实现对象

Properties

imp

• imp: any

内部实现对象

Methods

append

▸ append(val): void

向数组中添加一个值

Example

import { McGeLongArray } from "mxcad";

  const array = new McGeLongArray();
  array.append(5);
  array.append(10)

Parameters

Name	Type	Description
val	number	整数值

Returns

void

---

at

▸ at(index): number

根据数组索引得到数据元素的值

Example

import { McGeLongArray } from "mxcad"

  const array = new McGeLongArray();
  array.append(5);
  array.append(10);

  console.log(array.at(0)); // 输出: 5
  console.log(array.at(1)); // 输出: 10

Parameters

Name	Type	Description
index	number	数组索引

Returns

number

返回元素值

---

clear

▸ clear(): void

清空数组

Example

// array为整数数组
array.clear()

Returns

void

---

copy

▸ copy(val): McGeLongArray

复制对象的值

Example

import { McGeLongArray } from "mxcad"

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

  // 复制 array2 的值到 array1
  array1.copy(array2);

Parameters

Name	Type	Description
val	McGeLongArray	整数数组

Returns

McGeLongArray

---

copyFormAryId

▸ copyFormAryId(aryId): McGeLongArray

从 McObjectId 数组中复制值

Example

//objectIdArray 为一个对象id数组
  const array = new McGeLongArray();
  array.copyFormAryId(objectIdArray);

Parameters

Name	Type	Description
aryId	McObjectId[]	McObjectId 数组

Returns

McGeLongArray

---

forEach

▸ forEach(call): void

遍历数组

Example

import { McGeLongArray } from "mxcad"

  const array = new McGeLongArray();
  array.append(5);
  array.append(10);

  array.forEach((val, index) => {
    console.log(`Index ${index}: Value ${val}`);
  });
  // 输出:
  // Index 0: Value 5
  // Index 1: Value 10

Parameters

Name	Type	Description
call	(val: number, index: number) => void	回调函数

Returns

void

---

length

▸ length(): number

返回数组长度

Example

import { McGeLongArray } from "mxcad"

  const array = new McGeLongArray();
  console.log(array.length()); // 输出: 0

Returns

number

数组长度

---

setAt

▸ setAt(index, val): void

通过数组索引设置数据元素的值

Example

import { McGeLongArray } from "mxcad"

  const array = new McGeLongArray();
  array.append(5);
  array.append(10);

  array.setAt(0, 15);
  console.log(array.at(0)); // 输出: 15

Parameters

Name	Type	Description
index	number	数组索引值
val	number	整数数值

Returns

void
