Method Detail

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

getErrorCode

protected String getErrorCode()

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

Parameters:

decl - the declaration to be validated

Throws:

XPathException - if any error is found during validation

getStable

protected Expression getStable()

prepareAttributes

protected 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

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.

Overrides:

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 - if validation fails

getSortKeyDefinition

public SortKeyDefinition getSortKeyDefinition()
