- Method Detail
  - values
```
public static Operator[] 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 (Operator c : Operator.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Operator 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
  - getSymbol
```
public String getSymbol()
```
    Gets the symbol.
    
    Returns:
    
    the symbol
  - shouldEscape
```
public boolean shouldEscape()
```
    Should escape.
    
    Returns:
    
    true, if successful
  - toString
```
public String toString()
```
    To string.
    
    Overrides:
    
    toString in class Enum<Operator>
    
    Returns:
    
    the string
