This class takes care of the translation of ints, strings and arrays to the format required by the Sphinx service.
# File lib/riddle/client/message.rb, line 6 def initialize @message = "" @size_method = @message.respond_to?(:bytesize) ? :bytesize : :length end
Append raw data (only use if you know what you're doing)
# File lib/riddle/client/message.rb, line 12 def append(*args) args.each { |arg| @message << arg } end
# File lib/riddle/client/message.rb, line 27 def append_64bit_int(int) @message << [int.to_i >> 32, int.to_i & 0xFFFFFFFF].pack('NN') end
# File lib/riddle/client/message.rb, line 45 def append_64bit_ints(*ints) ints.each { |int| append_64bit_int(int) } end
Append an array of strings - first appends the length of the array, then each item's length and value.
# File lib/riddle/client/message.rb, line 56 def append_array(array) append_int(array.length) array.each { |item| append_string(item) } end
# File lib/riddle/client/message.rb, line 36 def append_boolean(bool) append_int(bool ? 1 : 0) end
Append a float
# File lib/riddle/client/message.rb, line 32 def append_float(float) @message << [float].pack('f').unpack('L*').pack("N") end
Append multiple floats
# File lib/riddle/client/message.rb, line 50 def append_floats(*floats) floats.each { |float| append_float(float) } end
Append an integer
# File lib/riddle/client/message.rb, line 23 def append_int(int) @message << [int.to_i].pack('N') end
Append multiple integers
# File lib/riddle/client/message.rb, line 41 def append_ints(*ints) ints.each { |int| append_int(int) } end
Append a string's length, then the string itself
# File lib/riddle/client/message.rb, line 17 def append_string(str) string = Riddle.encode(str.dup, 'ASCII-8BIT') @message << [string.send(@size_method)].pack('N') + string end
Returns the entire message
# File lib/riddle/client/message.rb, line 63 def to_s @message end
