Modifier and Type	Method	Description
`SqlNode`	`convertCall(RexToSqlNodeConverter converter, RexCall call)`	Converts a call to an operator into a `SqlCall` to the same operator.

- Method Detail
  - convertCall
```
public SqlNode convertCall(RexToSqlNodeConverter converter,
                           RexCall call)
```
    Converts a call to an operator into a SqlCall to the same operator.
    Called automatically via reflection.
    
    Parameters:
    
    converter - Converter
    
    call - Call
    
    Returns:
    
    Sql call
  - convertExpressionList
```
private SqlNode[] convertExpressionList(RexToSqlNodeConverter converter,
                                        java.util.List<RexNode> nodes)
```
  - registerEquivOp
```
protected void registerEquivOp(SqlOperator op)
```
    Creates and registers a convertlet for an operator in which the SQL and Rex representations are structurally equivalent.
    
    Parameters:
    
    op - operator instance
  - registerTypeAppendOp
```
private void registerTypeAppendOp(SqlOperator op)
```
    Creates and registers a convertlet for an operator in which the SQL representation needs the result type appended as an extra argument (e.g. CAST).
    
    Parameters:
    
    op - operator instance
  - registerCaseOp
```
private void registerCaseOp(SqlOperator op)
```
    Creates and registers a convertlet for the CASE operator, which takes different forms for SQL vs Rex.
    
    Parameters:
    
    op - instance of CASE operator
