- Method Detail
  - rexArguments
```
java.util.List<RexNode> rexArguments()
```
    Returns RexNode representation of arguments. This can be useful for manual translation of required arguments with different NullPolicy.
    
    Returns:
    
    RexNode representation of arguments
  - rexFilterArgument
```
RexNode rexFilterArgument()
```
    Returns RexNode representation of the filter, or null.
  - arguments
```
java.util.List<Expression> arguments()
```
    Returns Linq4j form of arguments. The resulting value is equivalent to rowTranslator().translateList(rexArguments()). This is handy if you need just operate on argument.
    
    Returns:
    
    Linq4j form of arguments.
  - rowTranslator
```
RexToLixTranslator rowTranslator()
```
    Returns a RexToLixTranslator suitable to transform the arguments.
    
    Returns:
    
    RexToLixTranslator suitable to transform the arguments
