Interface StylesheetComponent

All Known Implementing Classes:

XSLAccumulator, XSLAttributeSet, XSLFunction, XSLGlobalParam, XSLGlobalVariable, XSLKey, XSLTemplate

public interface StylesheetComponent

This interface is implemented by all top-level XSL elements that can contain local variable declarations. Specifically, a top-level xsl:template, xsl:variable, xsl:param, or xsl:function element or an xsl:attribute-set, xsl:accumulator, or xsl:key element.

Method Summary

Modifier and Type	Method	Description
void	checkCompatibility(Component component)	Check the compatibility of this component with another component that it is overriding
void	generateByteCode(Optimizer opt)	Generate byte code if appropriate
Actor	getActor()	Get the corresponding Actor object that results from the compilation of this StylesheetComponent
SlotManager	getSlotManager()	Get the SlotManager associated with this stylesheet construct.
SymbolicName	getSymbolicName()	Get the symbolic name of the component, that is, the combination of the component kind and the qualified name
void	optimize(ComponentDeclaration declaration)	Optimize the stylesheet construct

Method Detail

getSlotManager

SlotManager getSlotManager()

Get the SlotManager associated with this stylesheet construct. The SlotManager contains the information needed to manage the local stack frames used by run-time instances of the code.

Returns:

the associated SlotManager object

optimize

void optimize(ComponentDeclaration declaration)
       throws XPathException

Optimize the stylesheet construct

Parameters:

declaration - the combination of the source XSLT element defining the component, and the module in which it appears

Throws:

XPathException

generateByteCode

void generateByteCode(Optimizer opt)
               throws XPathException

Generate byte code if appropriate

Parameters:

opt - the optimizer

Throws:

XPathException - if bytecode generation fails

getActor

Actor getActor()
        throws XPathException

Get the corresponding Actor object that results from the compilation of this StylesheetComponent

Returns:

the compiled ComponentCode

Throws:

XPathException - if generating the ComponentBody fails

java.lang.UnsupportedOperationException - for second-class components such as keys that support outwards references but not inwards references

getSymbolicName

SymbolicName getSymbolicName()

Get the symbolic name of the component, that is, the combination of the component kind and the qualified name

Returns:

the component's symbolic name

checkCompatibility

void checkCompatibility(Component component)
                 throws XPathException

Check the compatibility of this component with another component that it is overriding

Parameters:

component - the overridden component

Throws:

XPathException - if the components are not compatible (differing signatures)
