Method Summary
 boolean declaresDefaultNS()
          This method is now deprecated.
 void display(int indent)
          Displays the contents of the element
 void parseContents(Parser parser)
          Parse the contents of this syntax tree nodes (child nodes, XPath expressions, patterns and functions).
 void translate(ClassGenerator classGen, MethodGenerator methodGen)
          At runtime the compilation of xsl:element results in code that: (i) evaluates the avt for the name, (ii) checks for a prefix in the name (iii) generates a new prefix and create a new qname when necessary (iv) calls startElement() on the handler (v) looks up a uri in the XML when the prefix is not known at compile time (vi) calls namespace() on the handler (vii) evaluates the contents (viii) calls endElement().
 void translateContents(ClassGenerator classGen, MethodGenerator methodGen)
          Override this method to make sure that xsl:attributes are not copied to output if this xsl:element is to be ignored
 void translateLiteral(ClassGenerator classGen, MethodGenerator methodGen)
          This method is called when the name of the element is known at compile time.
 Type typeCheck(SymbolTable stable)
          Run type check on element name & contents

Constructor Detail

XslElement

XslElement()
Method Detail

display

public void display(int indent)
Displays the contents of the element

Overrides:
display in class SyntaxTreeNode
Parameters:
indent - Indentation level for syntax tree levels.

declaresDefaultNS

public boolean declaresDefaultNS()
This method is now deprecated. The new implemation of this class never declares the default NS.


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
Run type check on element name & contents

Overrides:
typeCheck in class Instruction
Parameters:
stable - The compiler/parser's symbol table
Throws:
TypeCheckError

translateLiteral

public void translateLiteral(ClassGenerator classGen,
                             MethodGenerator methodGen)
This method is called when the name of the element is known at compile time. In this case, there is no need to inspect the element name at runtime to determine if a prefix exists, needs to be generated, etc.


translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)
At runtime the compilation of xsl:element results in code that: (i) evaluates the avt for the name, (ii) checks for a prefix in the name (iii) generates a new prefix and create a new qname when necessary (iv) calls startElement() on the handler (v) looks up a uri in the XML when the prefix is not known at compile time (vi) calls namespace() on the handler (vii) evaluates the contents (viii) calls endElement().

Overrides:
translate in class Instruction
Parameters:
classGen - BCEL Java class generator
methodGen - BCEL Java method generator

translateContents

public void translateContents(ClassGenerator classGen,
                              MethodGenerator methodGen)
Override this method to make sure that xsl:attributes are not copied to output if this xsl:element is to be ignored

Overrides:
translateContents in class SyntaxTreeNode
Parameters:
classGen - BCEL Java class generator
methodGen - BCEL Java method generator
