Consts

The Consts module is responsible for publishing all library wide constants.

These constants have three types:

• Type Codes

  • UNDEFINED - undefined or not yet initialized fields
  • BYTE - one byte long field
  • UBYTE - unsigned byte field
  • SHORT - 16 bits signed field
  • INTEGER - 32 bits signed integer field
  • LONG - 64 bits signed long field
  • SHORTSTRING - a single character string with a maximum length of 255 characters
  • CHAR - a single byte character
  • DOUBLECHAR - a double byte character (UTF-16-BigEndian)
  • LONGSTRING - a string with an integer size descriptor
  • WIDESTRING - a double character string with an integer size descriptor (UTF-16)
  • ARRAY - an array of fields.
  • RECORD - a record of fields (Not Implemented)

• Character Type Codes - these are used to translate type codes to a single character used in many other functions, especially in MultimodalMiddlewareProtocol.FieldFactory methods.

  • CHAR_BYTE - byte field
  • CHAR_UBYTE - unsigned byte field
  • CHAR_SHOR - short field
  • CHAR_INTEGER - integer field
  • CHAR_LONG - long field
  • CHAR_SHORTSTRINGS - short string field
  • CHAR_CHAR - char field
  • CHAR_DOUBLECHAR - double char field
  • CHAR_LONGSTRING - long string field
  • CHAR_WIDESTRING - wide string field
  • CHAR_ARRAY - array field
  • CHAR_RECORD - record field
  • CHAR_UNDEFINED - underfined type field

• Protocol Codes

  • PROT_UDP - UDP protocol
  • PROT_TCP - TCP protocol
