    • Method Detail

      • getBindingInformation

        public SourceBinding getBindingInformation​(StructuredQName name)
        Ask whether this element contains a binding for a variable with a given name; and if it does, return the source binding information
        Overrides:
        getBindingInformation in class StyleElement
        Parameters:
        name - the variable name
        Returns:
        the binding information if this element binds a variable of this name; otherwise null

      • getSlotNumber

        public int getSlotNumber()
        Get the slot number allocated to this variable (its position in the stackframe)
        Returns:
        the allocated slot number

      • 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: XSLGeneralVariable
        Check that the variable is not already declared, and allocate a slot number
        Overrides:
        validate in class XSLGeneralVariable
        Parameters:
        decl - the declaration being validated. A single XSLVariableDeclaration object may represent multiple declarations if it appears in a stylesheet module that is included/imported more than once
        Throws:
        XPathException - if any error is found during validation

      • isTunnelParam

        public boolean isTunnelParam()

      • isRequiredParam

        public boolean isRequiredParam()

      • fixupReferences

        public void fixupReferences()
                     throws XPathException
        Description copied from class: StyleElement
        Fix up references from XPath expressions. Overridden for function declarations and variable declarations
        Overrides:
        fixupReferences in class StyleElement
        Throws:
        XPathException - if any references cannot be fixed up.

      • 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

      • getCompiledParam

        public LocalParam getCompiledParam()

      • getRequiredType

        public SequenceType getRequiredType()
        Get the static type of the parameter. This is the declared type, because we cannot know the actual value in advance.
        Returns:
        the declared type (or item()* if no type is declared)
