```
public static RelationalOpEnum[] 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 (RelationalOpEnum c : RelationalOpEnum.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static RelationalOpEnum 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
  - reversed
```
public RelationalOpEnum reversed()
```
  - parse
```
public static RelationalOpEnum parse(String op)
```
    Parses the operator and returns an enum for the operator.
    
    Parameters:
    
    op - to parse
    
    Returns:
    
    enum representing relational operation
  - getComputer
```
public RelationalOpEnum.Computer getComputer(Class coercedType,
                                             Class typeOne,
                                             Class typeTwo)
```
    Returns the computer to use for the relational operation based on the coercion type.
    
    Parameters:
    
    coercedType - is the object type
    
    typeOne - the compare-to type on the LHS
    
    typeTwo - the compare-to type on the RHS
    
    Returns:
    
    computer for performing the relational op
  - getExpressionText
```
public String getExpressionText()
```
    Returns string rendering of enum.
    
    Returns:
    
    relational op string
