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.

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
