  • Constructor Details

    • SaxonAssign

      public SaxonAssign()

  • Method Details

    • isInstruction

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

    • isAssignable

      public boolean isAssignable()
      Description copied from class: XSLGeneralVariable
      Test whether it is permitted to assign to the variable using the saxon:assign extension element. This will only be true if the extra attribute saxon:assignable="yes" is present.
      Overrides:
      isAssignable in class XSLGeneralVariable

    • allowsAsAttribute

      protected boolean allowsAsAttribute()
      Overrides:
      allowsAsAttribute in class XSLGeneralVariable

    • validate

      public void validate() 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 XSLGeneralVariable
      Throws:
      XPathException

    • compile

      public Expression compile(Executable exec) throws XPathException
      Description copied from class: StyleElement
      Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.
      Specified by:
      compile in class StyleElement
      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
