XSLKey

public XSLKey()

Method Detail

isDeclaration

public boolean isDeclaration()

Description copied from class: StyleElement

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

Overrides:

isDeclaration in class StyleElement

Returns:

true if the element is a permitted child of xsl:stylesheet or xsl:transform

mayContainSequenceConstructor

public boolean mayContainSequenceConstructor()

Determine whether this type of element is allowed to contain a sequence constructor

Overrides:

mayContainSequenceConstructor in class StyleElement

Returns:

true: yes, it may contain a sequence constructor

getSlotManager

public SlotManager getSlotManager()

Get the Procedure object that looks after any local variables declared in the content constructor

Specified by:

getSlotManager in interface StylesheetProcedure

Returns:

the associated SlotManager object

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

getKeyName

public StructuredQName getKeyName()

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

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

compile

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

Description copied from class: StyleElement

Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

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

optimize

public void optimize(Declaration declaration)
              throws XPathException

Optimize the stylesheet construct

Specified by:

optimize in interface StylesheetProcedure

Parameters:

declaration -

Throws:

XPathException
