Method Detail

getIndex

public int getIndex()

parseContents

public void parseContents(Parser parser)

Parse the contents of the variable

Overrides:

parseContents in class VariableBase

Parameters:

parser - reference to the XSLT parser

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Runs a type check on either the variable element body or the expression in the 'select' attribute

Overrides:

typeCheck in class TopLevelElement

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

initialize

public void initialize(ClassGenerator classGen,
                       MethodGenerator methodGen)

This method is part of a little trick that is needed to use local variables inside nested for-each loops. See the initializeVariables() method in the ForEach class for an explanation

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

Description copied from class: TopLevelElement

Translate this node into JVM bytecodes.

Overrides:

translate in class TopLevelElement

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator
