Part (hutool 5.8.33 API)

java.lang.Object
- java.lang.Enum<Part>
- - cn.hutool.cron.pattern.Part

All Implemented Interfaces:

Serializable, Comparable<Part>
```
public enum Part
extends Enum<Part>
```
表达式各个部分的枚举，用于限定在表达式中的位置和规则（如最小值和最大值）
Enum.ordinal()表示此部分在表达式中的位置，如0表示秒
表达式各个部分的枚举位置为：
```
         0       1    2        3         4       5         6
     [SECOND] MINUTE HOUR DAY_OF_MONTH MONTH DAY_OF_WEEK [YEAR]
 
```

```
public static Part[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (Part c : Part.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Part valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getCalendarField
```
public int getCalendarField()
```
    获取Calendar中对应字段项
    
    Returns:
    
    Calendar中对应字段项
  - getMin
```
public int getMin()
```

    最小值
  - getMax
```
public int getMax()
```
    获取最大值
    
    Returns:
    
    最大值

```
public int checkValue(int value)
               throws CronException
```
    检查单个值是否有效
    
    Parameters:
    
    value - 值
    
    Returns:
    
    检查后的值
    
    Throws:

```
public static Part of(int i)
```
    根据位置获取Part
    
    Parameters:
    
    i - 位置，从0开始
    
    Returns:
