getModeName

public org.apache.xalan.xsltc.compiler.QName getModeName()

compareTo

public int compareTo(Object template)

Compare this template to another. First checks priority, then position.

display

public void display(int indent)

Description copied from class: SyntaxTreeNode

Displays the contents of this syntax tree node (to stdout). This method is intended for debugging _only_, and should be overridden by all syntax tree node implementations.

Parameters:

indent - Indentation level for syntax tree levels.

getStylesheet

public Stylesheet getStylesheet()

Description copied from class: SyntaxTreeNode

Get the Stylesheet node that represents the element that this node occured under.

Overrides:

getStylesheet in class SyntaxTreeNode

Returns:

The Stylesheet ancestor node of this node.

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

parseSimplified

public void parseSimplified(Stylesheet stylesheet,
                   Parser parser)

When the parser realises that it is dealign with a simplified stylesheet it will create an empty Stylesheet object with the root element of the stylesheet (a LiteralElement object) as its only child. The Stylesheet object will then create this Template object and invoke this method to force some specific behaviour. What we need to do is: o) create a pattern matching on the root node o) add the LRE root node (the only child of the Stylesheet) as our only child node o) set the empty Stylesheet as our parent o) set this template as the Stylesheet's only child

typeCheck

public Type typeCheck(org.apache.xalan.xsltc.compiler.SymbolTable stable)
               throws TypeCheckError

Type check all the children of this node.

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

translate

public void translate(ClassGenerator classGen,
             MethodGenerator methodGen)

Translate this node into JVM bytecodes.

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator

compile

public InstructionList compile(ClassGenerator classGen,
                      MethodGenerator methodGen)

Translate this node into a fresh instruction list. The original instruction list is saved and restored.

addDependency

public void addDependency(org.apache.xalan.xsltc.compiler.TopLevelElement other)

Add a dependency with other top-level elements like variables, parameters or keys.

getDependencies

public Vector getDependencies()

Get the list of dependencies with other top-level elements like variables, parameteres or keys.
