Constructor Detail

XSLTemplate

public XSLTemplate()

Method Detail

isDeclaration

public boolean isDeclaration()

Ask whether this node is a declaration, that is, a permitted child of xsl:stylesheet (including xsl:include and xsl:import).

Overrides:

isDeclaration in class StyleElement

Returns:

true for this element

mayContainSequenceConstructor

public boolean mayContainSequenceConstructor()

Determine whether this type of element is allowed to contain a template-body

Overrides:

mayContainSequenceConstructor in class StyleElement

Returns:

true: yes, it may contain a template-body

mayContainParam

protected boolean mayContainParam(java.lang.String attName)

Description copied from class: StyleElement

Determine whether this type of element is allowed to contain an xsl:param element

Overrides:

mayContainParam in class StyleElement

Parameters:

attName - if null, the method tests whether an xsl:param child is allowed. If non-null, it tests whether an xsl:param child with the given attribute name is allowed

Returns:

true if this element is allowed to contain an xsl:param

isPermittedChild

protected boolean isPermittedChild(StyleElement child)

Specify that xsl:param is a permitted child

Overrides:

isPermittedChild in class StyleElement

Parameters:

child - the child that may or may not be permitted

Returns:

true if the child is permitted.

getTemplateName

public StructuredQName getTemplateName()

Return the name of this template. Note that this may be called before prepareAttributes has been called.

Returns:

the name of the template as a Structured QName.

getReturnedItemType

protected ItemType getReturnedItemType()

Determine the type of item returned by this template

Overrides:

getReturnedItemType in class StyleElement

Returns:

the item type returned

prepareAttributes

public void prepareAttributes()
                       throws XPathException

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

Throws:

XPathException

validate

public void validate(Declaration 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

Throws:

XPathException

postValidate

public void postValidate()
                  throws XPathException

Description copied from class: StyleElement

Hook to allow additional validation of a parent element immediately after its children have been validated.

Overrides:

postValidate in class StyleElement

Throws:

XPathException

index

protected void index(Declaration 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 - the outermost XSLStylesheet element

Throws:

XPathException

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

compile

public Expression compile(Executable exec,
                          Declaration decl)
                   throws XPathException

Compile: creates the executable form of the template

Specified by:

compile in class StyleElement

Parameters:

exec - the Executable

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

Returns:

either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.

Throws:

XPathException

register

public void register(Declaration 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

optimize

public void optimize(Declaration declaration)
              throws XPathException

This method is a bit of a misnomer, because it does more than invoke optimization of the template body. In particular, it also registers the template rule with each Mode that it belongs to.

Specified by:

optimize in interface StylesheetProcedure

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

getSlotManager

public SlotManager getSlotManager()

Get associated Procedure (for details of stack frame)

Specified by:

getSlotManager in interface StylesheetProcedure

Returns:

the associated SlotManager object

getCompiledTemplate

public Template getCompiledTemplate()

Get the compiled template

Returns:

the compiled template

getConstructType

public int getConstructType()

Get the type of construct. This will be a constant in class Location. This method is part of the InstructionInfo interface

Specified by:

getConstructType in interface InstructionInfo

Overrides:

getConstructType in class StyleElement

Returns:

an integer identifying the kind of construct
