## 타입과 검증

이 환경변수들은 오직 **텍스트 문자열**로만 처리할 수 있습니다. 텍스트 문자열은 파이썬 외부에 있으며 다른 프로그램 및 나머지 시스템(Linux, Windows, macOS 등 다른 운영 체제)과 호환되어야 합니다.

## 类型和验证

这些环境变量只能处理**文本字符串**，因为它们是处于 Python 范畴之外的，必须与其他程序和操作系统的其余部分兼容（甚至与不同的操作系统兼容，如 Linux、Windows、macOS）。

这意味着从环境变量中读取的**任何值**在 Python 中都将是一个 `str`，任何类型转换或验证都必须在代码中完成。

          // requireNonNull is safe because right must exist in order to get a negative factor.
          requireNonNull(right);
          if (right.balanceFactor() > 0) {
            right = right.rotateRight();
          }
          return rotateLeft();
        case 2:
          // requireNonNull is safe because left must exist in order to get a positive factor.
          requireNonNull(left);
          if (left.balanceFactor() < 0) {

// 在此之後這個環境變數將不再存在
$ python main.py

Hello World from Python

## 型別和驗證

這些環境變數只能處理**文字字串**，因為它們是位於 Python 範疇之外的，必須與其他程式和作業系統的其餘部分相容（甚至與不同的作業系統相容，如 Linux、Windows、macOS）。

這意味著從環境變數中讀取的**任何值**在 Python 中都將是一個 `str`，任何型別轉換或驗證都必須在程式碼中完成。

          // requireNonNull is safe because right must exist in order to get a negative factor.
          requireNonNull(right);
          if (right.balanceFactor() > 0) {
            right = right.rotateRight();
          }
          return rotateLeft();
        case 2:
          // requireNonNull is safe because left must exist in order to get a positive factor.
          requireNonNull(left);
          if (left.balanceFactor() < 0) {

   * can hold setSize elements with the desired load factor. Always returns at least setSize + 2.
   */
  // TODO(cpovirk): Move to Hashing or something, since it's used elsewhere in the Android version.
  static int chooseTableSize(int setSize) {
    setSize = max(setSize, 2);
    // Correct the size for open addressing to match desired load factor.
    if (setSize < CUTOFF) {

max_wait  (duration)  maximum wait time between operations, defaults to '15s'
cycle     (duration)  time duration between scanner cycles
```

Example: the following setting will decrease the scanner speed by a factor of 3, reducing the system resource use, but increasing the latency of updates being reflected.

```sh
~ mc admin config set alias/ scanner delay=30.0
```
