public void compileToIterator(CompilerService compiler,
                              Expression expression)
                       throws CannotCompileException

    Description copied from class: ExpressionCompiler
    
    Generate bytecode to evaluate the expression as a SequenceIterator Precondition: none. Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression
    
    Specified by:
    
    compileToIterator in class ExpressionCompiler
    
    Parameters:
    
    compiler - the compiler service
    
    expression - the expression to be compiled
    
    Throws:
    
    CannotCompileException - if the expression cannot be compiled to bytecode
  - compileSortKeyDefinitions
```
public static int compileSortKeyDefinitions(CompilerService compiler,
                                            SortKeyDefinitionList definitions)
```
    Generate code to evaluate variable parts of the sort key definitions
    
    Parameters:
    
    compiler - the bytecode compiler
    
    definitions - the array of sort key definitions
    
    Returns:
    
    the identifier of a variable which will contain the run-time atomic comparers
