      public StructuredQName getObjectName()
      Description copied from class: StyleElement
      Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically. If there is no name, the value will be null.
      Overrides:
      getObjectName in class StyleElement
      Returns:
      the name of the object declared in this element, if any

    • mayContainSequenceConstructor

      protected boolean mayContainSequenceConstructor()
      Determine whether this type of element is allowed to contain a template-body
      Overrides:
      mayContainSequenceConstructor in class StyleElement
      Returns:
      true: yes, it may contain a template-body

    • isGlobal

      public boolean isGlobal()
      Test whether this is a global variable or parameter

      true if this is global

    • validate

      public void validate(ComponentDeclaration decl) throws XPathException

      Overrides:
      validate in class StyleElement
      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

    • postValidate

      public void postValidate() throws XPathException
      Hook to allow additional validation of a parent element immediately after its children have been validated.
