Method Detail

• emitHeader

  public void emitHeader(String name,
                String value)

  Pass a single header to the recipient.

  Parameters:

  name - Header name

  value - Header value

• validateHeaders

  public void validateHeaders()
                       throws StreamException

  Are the headers pass to the recipient so far valid? The decoder needs to process all the headers to maintain state even if there is a problem. In addition, it is easy for the the intended recipient to track if the complete set of headers is valid since to do that state needs to be maintained between the parsing of the initial headers and the parsing of any trailer headers. The recipient is the best place to maintain that state.

  Throws:

  StreamException - If the headers received to date are not valid

• setHeaderException

  public void setHeaderException(StreamException streamException)

  Inform the recipient of the headers that a stream error needs to be triggered using the given message when validateHeaders() is called. This is used when the Parser becomes aware of an error that is not visible to the recipient.

  Parameters:

  streamException - The exception to use when resetting the stream
