Method Detail

inInnerClass

public boolean inInnerClass()

Returns true if this closure is compiled in an inner class (i.e. if this is a real closure).

Specified by:

inInnerClass in interface Closure

getParentClosure

public Closure getParentClosure()

Returns a reference to its parent closure or null if outermost.

Specified by:

getParentClosure in interface Closure

getInnerClassName

public String getInnerClassName()

Returns the name of the auxiliary class or null if this predicate is compiled inside the Translet.

Specified by:

getInnerClassName in interface Closure

addVariable

public void addVariable(VariableRefBase variableRef)

Add new variable to the closure.

Specified by:

addVariable in interface Closure

parseContents

public void parseContents(Parser parser)

Parse the attributes of the xsl:sort element

Overrides:

parseContents in class SyntaxTreeNode

Parameters:

parser - reference to the XSLT parser

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Run type checks on the attributes; expression must return a string which we will use as a sort key

Overrides:

typeCheck in class Instruction

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

translateSortType

public void translateSortType(ClassGenerator classGen,
                     MethodGenerator methodGen)

These two methods are needed in the static methods that compile the overloaded NodeSortRecord.compareType() and NodeSortRecord.sortOrder()

translateSortOrder

public void translateSortOrder(ClassGenerator classGen,
                      MethodGenerator methodGen)

translateCaseOrder

public void translateCaseOrder(ClassGenerator classGen,
                      MethodGenerator methodGen)

translateLang

public void translateLang(ClassGenerator classGen,
                 MethodGenerator methodGen)

translateSelect

public void translateSelect(ClassGenerator classGen,
                   MethodGenerator methodGen)

This method compiles code for the select expression for this xsl:sort element. The method is called from the static code-generating methods in this class.

translate

public void translate(ClassGenerator classGen,
             MethodGenerator methodGen)

This method should not produce any code

Overrides:

translate in class Instruction

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator

translateSortIterator

public static void translateSortIterator(ClassGenerator classGen,
                         MethodGenerator methodGen,
                         Expression nodeSet,
                         Vector sortObjects)

Compiles code that instantiates a SortingIterator object. This object's constructor needs referencdes to the current iterator and a node sort record producing objects as its parameters.

compileSortRecordFactory

public static void compileSortRecordFactory(Vector sortObjects,
                            ClassGenerator classGen,
                            MethodGenerator methodGen)

Compiles code that instantiates a NodeSortRecordFactory object which will produce NodeSortRecord objects of a specific type.

compileSortRecordFactory

public static String compileSortRecordFactory(Vector sortObjects,
                              ClassGenerator classGen,
                              MethodGenerator methodGen,
