Constructor Detail

AbsentExtensionElement

public AbsentExtensionElement()

Method Detail

isInstruction

public boolean isInstruction()

Description copied from class: StyleElement

Ask whether this node is an instruction. The default implementation says it isn't.

Overrides:

isInstruction in class StyleElement

Returns:

true if this element is an instruction

mayContainSequenceConstructor

protected boolean mayContainSequenceConstructor()

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

Overrides:

mayContainSequenceConstructor in class StyleElement

Returns:

true if this instruction is allowed to contain a sequence constructor

processAllAttributes

public void processAllAttributes()
                          throws XPathException

Process the attributes of this element and all its children

Overrides:

processAllAttributes in class StyleElement

Throws:

XPathException - in the event of a static error being detected

prepareAttributes

protected 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

markTailCalls

protected boolean markTailCalls()

Mark tail-recursive calls on templates and functions. For most instructions, this does nothing.

Overrides:

markTailCalls in class StyleElement

Returns:

true if one or more tail calls were identified

validateSubtree

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

Recursive walk through the stylesheet to validate all nodes

Overrides:

validateSubtree in class StyleElement

Parameters:

decl - the declaration to be validated

excludeStylesheet - true if the XSLStylesheet element is to be excluded

Throws:

XPathException - if validation fails

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

compile

public Expression compile(Compilation exec,
                          ComponentDeclaration decl)
                   throws XPathException

Description copied from class: StyleElement

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

Overrides:

compile in class StyleElement

Parameters:

exec - the compilation episode

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 - if validation fails
