        false: no, it may not contain a sequence constructor

      • getForEachItem

        public Expression getForEachItem()
        Get the for-each-item expression, if it exists
        Returns:
        the for-each-item expression, if defined, or null otherwise

      • getForEachSource

        public Expression getForEachSource()
        Get the for-each-source expression, if it exists
        Returns:
        the for-each-source expression, if defined, or null otherwise

      • getSelect

        public Expression getSelect()
        Get the select expression
        Returns:

        Returns:
        true if the input sequence is to be sorted before merging

      • getSourceName

        public java.lang.String getSourceName()
        Get the name of the merge source, or null if not specified
        Returns:
        the value of the @name attribute, or null if the attribute was absent

      • getValidationAction

        public int getValidationAction()
        Get the value of the validation attribute, if present
        Returns:
        the value of the validation attribute

      • getSchemaTypeAttribute

        public SchemaType getSchemaTypeAttribute()
        Get the value of the type attribute, if present
        Returns:
        the value of the type attribute

      • 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

      • 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

      • 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
