    • hasComputedStyleErrors

      public boolean hasComputedStyleErrors()
      Description copied from interface: ErrorHandler
      Check whether this handler has processed computed style errors.

      Presentational hint errors are included in this category, as they are found during style computation.

      Specified by:
      hasComputedStyleErrors in interface ErrorHandler
      Returns:
      true if this handler processed computed style errors.

    • hasErrors

      public boolean hasErrors()
      Description copied from interface: ErrorHandler
      Check whether this handler has processed any non-transient error.

      I/O errors are not taken into account by this method.

      Specified by:
      hasErrors in interface ErrorHandler
      Returns:
      true if this handler processed any non-transient errors.

    • hasWarnings

      public boolean hasWarnings()
      Description copied from interface: ErrorHandler
      Check whether this handler has processed any warnings.
      Specified by:
      hasWarnings in interface ErrorHandler
      Returns:
      true if this handler processed any warnings.

    • linkedStyleError

      public void linkedStyleError(Node node, String message)
      Description copied from interface: ErrorHandler
      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:
      node - the node where the error happened.
      message - a message describing the error.

    • mediaQueryError

      public void mediaQueryError(Node node, CSSMediaException exception)
      Description copied from interface: ErrorHandler
      Report a media query error.
      Specified by:
      mediaQueryError in interface ErrorHandler
      Parameters:
      node - 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.

    • linkedSheetError

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

    • inlineStyleError

      public void inlineStyleError(CSSElement owner, Exception e, String context)
      Description copied from interface: ErrorHandler
      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.
      e - the exception describing the problem.
      context - the inline style.

    • computedStyleError

      public void computedStyleError(CSSElement element, String propertyName, CSSPropertyValueException exception)
      Description copied from interface: ErrorHandler
      Error found in computed style declaration.

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

      Specified by:
      computedStyleError in interface ErrorHandler
      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.

    • presentationalHintError

      public void presentationalHintError(CSSElement elm, DOMException e)
      Description copied from interface: ErrorHandler
      While computing a style, an error was found when processing the presentational hints of an element.
      Specified by:
      presentationalHintError in interface ErrorHandler
      Parameters:
      elm - the element.
      e - the exception describing the error found.

    • resetComputedStyleErrors

      public void resetComputedStyleErrors()
      Description copied from interface: ErrorHandler
      Reset the error state about computed styles and presentational hints.
      Specified by:
      resetComputedStyleErrors in interface ErrorHandler

    • reset

      public void reset()
      Description copied from interface: ErrorHandler
      Reset the error handler.

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

      Specified by:
      reset in interface ErrorHandler
