Method Detail

compileToCharSequence

public String compileToCharSequence(CompilerService compiler,
                                    Expression expr)

Description copied from class: ExpressionCompiler

Generate Java code to evaluate the expression as a CharSequence

Overrides:

compileToCharSequence in class SingletonExpressionCompiler

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, or a string literal) which will be of class CharSequence, and which will hold the string value of the XPath expression at run-time

compileToItem

public String compileToItem(CompilerService compiler,
                            Expression expr)

Description copied from class: ExpressionCompiler

Generate Java code to evaluate the expression as an Item

Specified by:

compileToItem 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 Item, and which will hold the value of the expression at run-time (or hold null, representing an empty sequence).
