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

compileRootArgument

public static String compileRootArgument(int n,
                                         SystemFunction exp,
                                         CompilerService compiler)
