- Method Detail
  - values
```
public static ExpressionPriority[] 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 (ExpressionPriority c : ExpressionPriority.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ExpressionPriority 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
  - valueOf
```
public static ExpressionPriority valueOf(InfixOperator operator)
```
    Returns the priority about the target infix operator.
    
    Parameters:
    
    operator - the infix operator
    
    Returns:
    
    the corresponded priority
    
    Throws:
    
    IllegalArgumentException - if the parameter is null
  - valueOf
```
public static ExpressionPriority valueOf(Expression expression)
```
    Returns the priority about the target expression.
    
    Parameters:
    
    expression - the target expression
    
    Returns:
    
    the corresponded priority
    
    Throws:
    
    IllegalArgumentException - if the parameter is null
  - isParenthesesRequired
```
public static boolean isParenthesesRequired(ExpressionPriority required,
                                            boolean requiredInRight,
                                            ExpressionPriority priority)
```
    Returns whether parentheses are required for comparing the priorities or not.
    
    Parameters:
    
    required - the required priority
    
    requiredInRight - true if the required priority appears in the right term of infix expressions, otherwise false
    
    priority - the target priority
    
    Returns:
    
    true if parentheses are required, otherwise false
    
    Throws:
    
    IllegalArgumentException - if the parameters are null
