Instance Method Details

#determine_content_length(frame) ⇒ Fixnum

Determines the content-length of a frame being sent to a broker. For Ruby 1.8.7, this is just the size of the frame’s body.

Returns:

  • (Fixnum) —

    byte-length of frame’s body

# File 'lib/stomper/support/1.8/frame_serializer.rb', line 41

def determine_content_length(frame)
  frame.body.size
end

#determine_content_type(frame) ⇒ String

Determines the content-type of a frame being sent to a broker. This version of the method is used by Ruby 1.8.7, which lacks native string encoding support. If the content-type matches ‘text/*’, and no charset parameter is set, a charset of UTF-8 will be assumed. In all other cases, the ‘content-type’ header is used directly.

Returns:

  • (String) —

    content-type and possibly charset of frame’s body

def determine_content_type(frame)
  ct = frame[:'content-type']
  if ct =~ /^text\//i && !(ct =~ /\;\s*charset=\"?[a-zA-Z0-9!\#$&.+\-^_]+\"?/i)
    "#{ct};charset=UTF-8"
  else
    ct
  end
end

#encode_body(body, ct_header) ⇒ String

Return the body with the specified encoding applied. Ruby 1.8 does not have a native awareness of string encodings. As such, this method does not change the body in any way.

Parameters:

  • body (String) —

    body of message to encode

  • ct (String) —

    content-type header of frame

Returns:

  • (String)

def encode_body(body, ct_header)
  body
end

#get_body_byte ⇒ String?

Reads a single byte from the body portion of a frame. Returns nil if the character read is a frame terminator.

Returns:

  • (String, nil) —

    the byte read from the stream.

def get_body_byte
  c = @io.getc.chr
  c == ::Stomper::FrameSerializer::FRAME_TERMINATOR ? nil : c
end

#get_header_line ⇒ String

Reads a line of text from the underlying IO. As per the Stomp 1.1 specification, all header strings are encoded with UTF-8.

Returns:

  • (String) —

    line of text read from IO, or ” if no text was read.
