public void prepareAttributes()

Description copied from class: StyleElement

Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:

prepareAttributes in class StyleElement

If #default is present explicitly or implicitly, it is replaced by the default mode, taken from the in-scope default-modes attribute, which defaults to #unnamed.

Throws:

XPathException - if the attribute is invalid.

XPathException

validate

public void validate(ComponentDeclaration decl)
              throws XPathException

Description copied from class: StyleElement

Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:

validate in class StyleElement

Parameters:

decl - the declaration to be validated

Throws:

XPathException - if any error is found during validation

validateSubtree

public void validateSubtree(ComponentDeclaration decl,
                            boolean excludeStylesheet)
                     throws XPathException

Description copied from class: StyleElement

Recursive walk through the stylesheet to validate all nodes

Overrides:

validateSubtree in class StyleElement

Parameters:

excludeStylesheet - true if the XSLStylesheet element is to be excluded

Throws:

XPathException - if validation fails

index

public void index(ComponentDeclaration decl,
                  PrincipalStylesheetModule top)
           throws XPathException

Description copied from class: StyleElement

Method supplied by declaration elements to add themselves to a stylesheet-level index

Overrides:

index in class StyleElement

Parameters:

decl - the Declaration being indexed. (This corresponds to the StyleElement object except in cases where one module is imported several times with different precedence.)

top - represents the outermost XSLStylesheet or XSLPackage element

Throws:

XPathException - if any error is encountered

markTailCalls

public boolean markTailCalls()

Mark tail-recursive calls on templates and functions.

Overrides:

markTailCalls in class StyleElement

Returns:

true if one or more tail calls were identified

                        throws XPathException

Compile: creates the executable form of the template

Overrides:

compileDeclaration in class StyleElement

Parameters:

compilation - the compilation episode

decl - the containing top-level declaration, for example xsl:function or xsl:template

Throws:

XPathException - if compilation fails

compileTemplateRule

public void compileTemplateRule(Compilation compilation,
                                Expression body,
                                ComponentDeclaration decl)

jitCompile

public void jitCompile(Compilation compilation,
                       ComponentDeclaration decl)
                throws XPathException

Code executed when the template is first executed under JIT. If the template is defined in several modes, then this may be called several times, but it only does anything the first time. Mode-specific processing is done in the TemplateRuleInitializer.

Parameters:

compilation - the compilation episode

decl - the template rule declaration

Throws:

XPathException - if anything goes wrong

register

public void register(ComponentDeclaration declaration)
              throws XPathException

Registers the template rule with each Mode that it belongs to.

Parameters:

declaration - Associates this template with a stylesheet module (in principle an xsl:template element can be in a document that is imported more than once; these are separate declarations)

Throws:

XPathException - if a failure occurs

allocatePatternSlotNumbers

public void allocatePatternSlotNumbers()

Allocate slot numbers to any local variables declared within a predicate within the match pattern

optimize

public void optimize(ComponentDeclaration declaration)
              throws XPathException

Specified by:

optimize in interface StylesheetComponent

Parameters:

declaration - Associates this template with a stylesheet module (in principle an xsl:template element can be in a document that is imported more than once; these are separate declarations)

Throws:

XPathException - if errors are found

getContextItemTypeForTemplateRule

public ItemType getContextItemTypeForTemplateRule()
                                           throws XPathException

Throws:

XPathException

generateByteCode

public void generateByteCode(Optimizer opt)
                      throws XPathException

Generate byte code for the template (if appropriate)

generateByteCode in interface StylesheetComponent

Parameters:

opt - the optimizer

Throws:

XPathException - if byte code generation fails

getSlotManager

public SlotManager getSlotManager()

Get associated Procedure (for details of stack frame)

Specified by:

getSlotManager in interface StylesheetComponent

Returns:

the associated SlotManager object

getCompiledNamedTemplate

public NamedTemplate getCompiledNamedTemplate()

Get the compiled template

Returns:

the compiled template
