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
