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 java.lang.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)

Description copied from class: SyntaxTreeNode

Parse the contents of this syntax tree nodes (child nodes, XPath expressions, patterns and functions). The default behaviour is to parser the syntax tree node's children (since there are no common expressions, patterns, etc. that can be handled in this base class.

Overrides:

parseContents in class SyntaxTreeNode

Parameters:

parser - reference to the XSLT parser

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Description copied from class: Instruction

Type check all the children of this node.

Overrides:

typeCheck in class Instruction

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

hasValue

public boolean hasValue()

True if the has specified a value for this instance of number.

isDefault

public boolean isDefault()

Returns true if this instance of number has neither a from nor a count pattern.

compileDefault

private void compileDefault(ClassGenerator classGen,
                            MethodGenerator methodGen)

compileConstructor

private void compileConstructor(ClassGenerator classGen)

Compiles a constructor for the class _className that inherits from {Any,Single,Multiple}NodeCounter. This constructor simply calls the same constructor in the super class.

compileLocals

private void compileLocals(NodeCounterGenerator nodeCounterGen,
                           MatchGenerator matchGen,
                           InstructionList il)

This method compiles code that is common to matchesFrom() and matchesCount() in the auxillary class.

compilePatterns

private void compilePatterns(ClassGenerator classGen,
                             MethodGenerator methodGen)

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

Description copied from class: Instruction

Translate this node into JVM bytecodes.

Overrides:

translate in class Instruction

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator
