    Description copied from interface: GrelExpr
    
    For GREL expressions, toString should return the source code of the expression, or a source code for an equivalent expression. (without the "grel:" prefix).
    
    Specified by:
    
    toString in interface GrelExpr
    
    Overrides:
    
    toString in class FunctionCallExpr
  - renameColumnDependencies
```
public ArrayExpr renameColumnDependencies(Map<String,String> substitutions)
```
    Description copied from interface: GrelExpr
    
    Translates this expression by simultaneously substituting column names as the supplied map specifies.
    This is only possible if the extraction of column dependencies with GrelExpr.getColumnDependencies(String) succeeds (return a non-null value).
    
    Specified by:
    
    renameColumnDependencies in interface GrelExpr
    
    Overrides:
    
    renameColumnDependencies in class FunctionCallExpr
    
    Parameters:
    
    substitutions - a map specifying new names for some columns. If a column name is not present in the map, it is assumed that the column is not renamed.
    
    Returns:
    
    a new expression with updated column names.
