Field Detail

### preserveAspectRatioHandler

    protected PreserveAspectRatioHandler preserveAspectRatioHandler

  The PreserveAspectRatio handler used to report parse events.

Constructor Detail

### PreserveAspectRatioParser

    public PreserveAspectRatioParser()

  Creates a new PreserveAspectRatioParser.

Method Detail

### setPreserveAspectRatioHandler

    public void setPreserveAspectRatioHandler(PreserveAspectRatioHandler handler)

  Allows an application to register a PreserveAspectRatioParser handler.

  If the application does not register a handler, all events reported by the parser will be silently ignored.

  Applications may register a new or different handler in the middle of a parse, and the parser must begin using the new handler immediately.

  Parameters:
    `handler` - The transform list handler.

### getPreserveAspectRatioHandler

    public PreserveAspectRatioHandler getPreserveAspectRatioHandler()

  Returns the length handler in use.

### doParse

    protected void doParse()
                    throws ParseException,
                           java.io.IOException

  Parses the current stream.

  Specified by:
    `doParse` in class `AbstractParser`
  Throws:
    `ParseException`
    `java.io.IOException`

### parsePreserveAspectRatio

    protected void parsePreserveAspectRatio()
                                     throws ParseException,
                                            java.io.IOException

  Parses a PreserveAspectRatio attribute.

  Throws:
    `ParseException`
    `java.io.IOException`

### skipIdentifier

    protected void skipIdentifier()
                           throws java.io.IOException

  Skips characters in the given reader until a white space is encountered.

  Returns:
    the first character after the space.
  Throws:
    `java.io.IOException`
