Constructor Detail

XSLAccumulator

public XSLAccumulator()

Method Detail

getActor

public Actor getActor()

Get the corresponding Procedure object that results from the compilation of this StylesheetProcedure

Specified by:

getActor in interface StylesheetComponent

Returns:

the compiled ComponentCode

getSymbolicName

public SymbolicName getSymbolicName()

Description copied from interface: StylesheetComponent

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

Specified by:

getSymbolicName in interface StylesheetComponent

Returns:

the component's symbolic name

checkCompatibility

public void checkCompatibility(Component component)
                        throws XPathException

Description copied from interface: StylesheetComponent

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

Specified by:

checkCompatibility in interface StylesheetComponent

Parameters:

component - the overridden component

Throws:

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

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

prepareSimpleAttributes

public void prepareSimpleAttributes()
                             throws XPathException

Method to handle the name attributes, which may need to be evaluated early if there are forwards references to this accumulator

Throws:

XPathException - if any error is detected

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 - if a static error is detected

compileDeclaration

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

Description copied from class: StyleElement

Compile a declaration in the stylesheet tree for use at run-time.

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

getObjectName

public StructuredQName getObjectName()

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically. If there is no name, the value will be -1.

Overrides:

getObjectName in class StyleElement

Returns:

the name of the object declared in this element, if any

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

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

getSlotManager

public SlotManager getSlotManager()

Description copied from interface: StylesheetComponent

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.

Specified by:

getSlotManager in interface StylesheetComponent

Returns:

the associated SlotManager object

optimize

public void optimize(ComponentDeclaration declaration)
              throws XPathException

Description copied from interface: StylesheetComponent

Optimize the stylesheet construct

Specified by:

optimize in interface StylesheetComponent

Parameters:

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

Throws:

XPathException

getResultType

public SequenceType getResultType()

Get the type of value returned by this function

Returns:

the declared result type, or the inferred result type if this is more precise

getConstructType

public int getConstructType()

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

Overrides:

getConstructType in class StyleElement

generateByteCode

public void generateByteCode(Optimizer opt)

Generate byte code if appropriate

Specified by:

generateByteCode in interface StylesheetComponent

Parameters:

opt - the optimizer
