- Method Detail
  - getAtomicComparer
```
AtomicComparer getAtomicComparer()
```
    Get the AtomicComparer used to compare atomic values. This encapsulates any collation that is used
    
    Returns:
    
    the comparer
  - getSingletonOperator
```
int getSingletonOperator()
```
    Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE
    
    Returns:
    
    the operator, as defined in class Token
  - getLhs
```
Operand getLhs()
```
    Get the left-hand operand of the comparison
    
    Returns:
    
    the first operand
  - getRhs
```
Operand getRhs()
```
    Get the right-hand operand of the comparison
    
    Returns:
    
    the second operand
  - getLhsExpression
```
Expression getLhsExpression()
```
    Get the left-hand expression
    
    Returns:
    
    the first operand expression
  - getRhsExpression
```
Expression getRhsExpression()
```
    Get the right-hand expression
    
    Returns:
    
    the second operand expression
  - convertsUntypedToOther
```
boolean convertsUntypedToOther()
```
    Determine whether untyped atomic values should be converted to the type of the other operand
    
    Returns:
    
    true if untyped values should be converted to the type of the other operand, false if they should be converted to strings.
