```
public static DirectionType[] values()
```
    按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示:
```
for (DirectionType c : DirectionType.values())
    System.out.println(c);
```
    返回:
    
    按照声明该枚举类型的常量的顺序返回的包含这些常量的数组
  - valueOf
```
public static DirectionType valueOf(String name)
```
    返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
    
    参数:
    
    name - 要返回的枚举常量的名称。
    
    返回:
    
    返回带有指定名称的枚举常量
    
    抛出:
    
    IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
    
    NullPointerException - 如果参数为空值
  - isAllDirectionType
```
public static boolean isAllDirectionType(DirectionType directionType)
```
    Is all direction type.
    
    参数:
    
    directionType - direction type
    
    返回:
    
    is all direction type or not
  - isForwardCountDirectionType
```
public static boolean isForwardCountDirectionType(DirectionType directionType)
```
    Is forward count direction type.
    
    参数:
    
    directionType - direction type
    
    返回:
    
    is forward count direction type or not
  - isBackwardCountDirectionType
```
public static boolean isBackwardCountDirectionType(DirectionType directionType)
```
    Is backward count direction type.
    
    参数:
    
    directionType - direction type
    
    返回:
    
    is backward count direction type or not
