Method Detail

### compileToIterator

    public String compileToIterator(CompilerService compiler,
                                    Expression expr)

  Description copied from class: `ExpressionCompiler`
  Generate Java code to evaluate the expression as a SequenceIterator

  Specified by:
    `compileToIterator` in class `ExpressionCompiler`
  Parameters:
    `compiler` - the compiler service
    `expr` - the XPath expression to be compiled
  Returns:
    a simple Java expression (usually the name of a variable that has been declared) which will be of class `SequenceIterator`, and which at run-time will hold an iterator over the the value of the XPath expression

### compileAsLoop

    public void compileAsLoop(CompilerService compiler,
                              Expression expr,
                              LoopAction action)

  Compile an expression in the form of a loop. Default implementation.

  Overrides:
    `compileAsLoop` in class `ExpressionCompiler`
  Parameters:
    `compiler` - the CompilerService
    `expr` - the expression to be compiled
    `action` - the action to be taken to process each item in the sequence returned by the expression
