Constructor Summary

WithParam()

Method Summary

void	display(int indent) Displays the contents of this element
java.lang.String	getEscapedName() Returns the escaped qname of the parameter
QName	getName() Return the name of this WithParam.
void	parseContents(Parser parser) The contents of a elements are either in the element's 'select' attribute (this has precedence) or in the element body.
void	setDoParameterOptimization(boolean flag) Set the do parameter optimization flag
void	setName(QName name) Set the name of the variable or paremeter.
void	translate(ClassGenerator classGen, MethodGenerator methodGen) This code generates a sequence of bytecodes that call the addParameter() method in AbstractTranslet.
void	translateValue(ClassGenerator classGen, MethodGenerator methodGen) Compile the value of the parameter, which is either in an expression in a 'select' attribute, or in the with-param element's body
Type	typeCheck(SymbolTable stable) Type-check either the select attribute or the element body, depending on which is in use.

Field Detail

_name

private QName _name

Parameter's name.

_escapedName

protected java.lang.String _escapedName

The escaped qname of the with-param.

_select

private Expression _select

Parameter's default value.

_doParameterOptimization

private boolean _doParameterOptimization

%OPT% This is set to true when the WithParam is used in a CallTemplate for a simple named template. If this is true, the parameters are passed to the named template through method arguments rather than using the expensive Translet.addParameter() call.

Method Detail

display

public void display(int indent)

Displays the contents of this element

Overrides:

display in class SyntaxTreeNode

Parameters:

indent - Indentation level for syntax tree levels.

getEscapedName

public java.lang.String getEscapedName()

Returns the escaped qname of the parameter

getName

public QName getName()

Return the name of this WithParam.

setName

public void setName(QName name)

Set the name of the variable or paremeter. Escape all special chars.

setDoParameterOptimization

public void setDoParameterOptimization(boolean flag)

Set the do parameter optimization flag

parseContents

public void parseContents(Parser parser)

The contents of a elements are either in the element's 'select' attribute (this has precedence) or in the element body.

Overrides:

parseContents in class SyntaxTreeNode

Parameters:

parser - reference to the XSLT parser

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Type-check either the select attribute or the element body, depending on which is in use.

Overrides:

typeCheck in class Instruction

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

translateValue

public void translateValue(ClassGenerator classGen,
                           MethodGenerator methodGen)

Compile the value of the parameter, which is either in an expression in a 'select' attribute, or in the with-param element's body

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

This code generates a sequence of bytecodes that call the addParameter() method in AbstractTranslet. The method call will add (or update) the parameter frame with the new parameter value.

Overrides:

translate in class Instruction

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator
