Class IXSLSetProperty

  • All Implemented Interfaces:
    javax.xml.transform.Source, javax.xml.transform.SourceLocator, ActiveSource, GroundedValue, Item, MutableNodeInfo, NamespaceResolver, NodeInfo, Sequence, Location, SteppingNode, SiblingCountingNode, org.xml.sax.Locator
    public class IXSLSetProperty
extends StyleElement
    Handler for ixsl:set-property elements in stylesheet. The ixsl:set-property element has mandatory attributes name (the name of the property to be set, or dot-separated composite name), and select (the new property value), and optional attributes object (the object that the property belongs to, when no object attribute is present, the window object is used) and convert-value (available from JS3, specifies whether the supplied new property value is converted from XDM to JS or retained in SaxonJS internal form.)

    • Method Detail

      • isInstruction

        public boolean isInstruction()
        Determine whether this node is an instruction.
        Overrides:
        isInstruction in class StyleElement
        Returns:
        true - it is an instruction

      • mayContainSequenceConstructor

        protected boolean mayContainSequenceConstructor()
        Determine whether this type of element is allowed to contain a sequence constructor
        Overrides:
        mayContainSequenceConstructor in class StyleElement
        Returns:
        false: no, the element must be empty

      • 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

      • 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
