      Parameters:
      element - the element.
      Returns:
      true if this handler processed computed style errors.

      Report a policy error, including possible security issues.
      Parameters:
      node - the node that caused the policy violation, or where it was detected.
      message - a message describing the error.

    • linkedStyleError

      void linkedStyleError(Node ownerNode, String message)
      Report an error related to linked style, where it was not possible to create the style sheet linked from node due to an issue with the given node or other node in the document (as opposed to an issue with the linked style sheet itself).
      Parameters:
      ownerNode - the node where the error happened.
      message - a message describing the error.

    • mediaQueryError

      void mediaQueryError(Node ownerNode, CSSMediaException exception)
      Report a media query error.
      Parameters:
      ownerNode - the node that ultimately owns the sheet or rule where the media query appears (even if it is inside a nested sheet/rule, the node responsible is the one that owns the top-most style sheet).
      exception - the exception describing the error.

    • mediaQueryWarning

      void mediaQueryWarning(Node ownerNode, CSSMediaException exception)
      Report a media query warning.
      Parameters:
      ownerNode - the node that ultimately owns the sheet or rule where the media query appears (even if it is inside a nested sheet/rule, the node responsible is the one that owns the top-most style sheet).
      exception - the exception describing the issue.

    • linkedSheetError

      void linkedSheetError(Exception exception, CSSStyleSheet<? extends CSSRule> sheet)
      Report an error associated to a LinkStyle style sheet (i.e. LINK or STYLE elements), that caused an exception to be thrown.
      Parameters:
      exception - the exception describing the problem.
      sheet - the linked or embedded style sheet.

    • ioError

      void ioError(String uri, IOException exception)
      A I/O error was found when retrieving a resource while processing an attribute (usually href) or a rule, generally an @import or @font-face rule.
      Parameters:
      uri - the uri for the resource.
      exception - the exception describing the problem.

    • nodeError

      default void nodeError(Node node, String message, Throwable t)
      A generic error was found when processing a Node, one that is not directly associated to a style sheet or declaration.

      It may be called while processing the URI of a document or a resource, generally the href attribute.

      Parameters:
      node - the node.
      message - the error message. May be null if an exception is provided.
      t - the exception, or null if there is a message.

    • getInlineStyleErrorHandler

      StyleDeclarationErrorHandler getInlineStyleErrorHandler(CSSElement owner)
      Get the error handler for the given element's inline style.
      Parameters:
      owner - the element that owns the inline style.
      Returns:
      the style's error handler. Implementations are allowed to return null if the element has no inline style.

    • inlineStyleError

      void inlineStyleError(CSSElement owner, Exception exception, String inlineStyle)
      Report a problem with setting an inline style, that caused an exception to be thrown by lower-level parsing (NSAC).

      This method is triggered only in two (unlikely) cases:

      1. If a problem appears when instantiating a NSAC parser.
      2. When the NSAC parser throws a CSSException.

      The NSAC parser does not throw a CSSException if there is an error handler set (and in this implementation there is always one), although other parsers may.

      Parameters:
      owner - the element owning the inline style.
      exception - the exception describing the problem.
      inlineStyle - the inline style.

    • computedStyleError

      void computedStyleError(CSSElement element, String propertyName, CSSPropertyValueException exception)
      Error found in computed style declaration.

      This means that an error could only be found when processing the values for computing the style.

      Parameters:
      element - the element for which the style was computed.
      propertyName - the name of the property involved in error.
      exception - the exception describing the error.

    • computedStyleWarning

      void computedStyleWarning(CSSElement element, String propertyName, CSSPropertyValueException exception)
      Error found in computed style declaration.

      This means that an error could only be found when processing the values for computing the style.

      Parameters:
      element - the element for which the style was computed.
      propertyName - the property name.
      exception - the exception describing the error.

    • presentationalHintError

      void presentationalHintError(CSSElement element, DOMException exception)
      While computing a style, an error was found when processing the presentational hints of an element.
      Parameters:
      element - the element.
      exception - the exception describing the error found.

    • resetComputedStyleErrors

      void resetComputedStyleErrors(CSSElement element)
      Reset the error state about computed styles and presentational hints for the given element.
      Parameters:
      element - the element.

    • resetComputedStyleErrors

      void resetComputedStyleErrors()
      Reset the error state about computed styles and presentational hints.

    • reset

      void reset()
      Reset the error handler.

      After calling this method, hasErrors() and hasWarnings() must return false;
