All Implemented Interfaces:

public class EncodingChangeException
extends ParserException

The encoding is changed invalidating already scanned characters. When the encoding is changed, as for example when encountering a <META> tag that includes a charset directive in the content attribute that disagrees with the encoding specified by the HTTP header (or the default encoding if none), the parser retraces the bytes it has interpreted so far comparing the characters produced under the new encoding. If the new characters differ from those it has already yielded to the application, it throws this exception to indicate that processing should be restarted under the new encoding. This exception is the object thrown so that applications may distinguish between an encoding change, which may be successfully cured by restarting the parse from the beginning, from more serious errors.
