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

compileToValueRepresentation

public String compileToValueRepresentation(CompilerService compiler,
                                           Expression expr)
Description copied from class: ExpressionCompiler
Generate Java code to evaluate the expression as a ValueRepresentation

Overrides:
compileToValueRepresentation in class ExpressionCompiler
Parameters:
compiler - the compiler service
expr - the expression to be compiled
Returns:
a simple Java expression (usually the name of a variable that has been declared) which will be of class ValueRepresentation, and which at run-time will hold the value of the expression
