    • mayContainSequenceConstructor

      public boolean mayContainSequenceConstructor()
      Description copied from class: StyleElement
      Determine whether this type of element is allowed to contain a sequence constructor
      Overrides:
      mayContainSequenceConstructor in class StyleElement
      Returns:
      true if this instruction is allowed to contain a sequence constructor

    • prepareAttributes

      public 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

    • 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

    • 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

    • quoteSqlName

      public static String quoteSqlName(String name) throws IllegalArgumentException
      Utility method to quote a SQL table or column name if it needs quoting.
      Parameters:
      name - the supplied name
      Returns:
      the supplied name, enclosed in double quotes if it does not satisfy the pattern [A-Za-z_][A-Za-z0-9_]*, with any double quotes replaced by two double quotes
      Throws:
      IllegalArgumentException
