MOST: General Tips on XML Function Catalog Support in CAPL

Valid for: CANoe DE Tips for using XML-based CAPL functions for the symbolic description of messages and parameters. There are two different access formats when using XML function catalogs in CAPL:

​
Compile Time

  • The symbols are checked and resolved during compilation.
  • Compile time access is very efficient.
Example: 
mostAmsMessage AudioDiskPlayer.TrackPosition.Status msg;
msg.Track = 3;

​
Runtime

  • Since the symbols are interpreted during runtime, this access format is less efficient.
  • Faulty symbols cause the measurement process to be aborted.
  • Runtime access is the only possible access format for parameters with variable length/position (e.g., strings) and nested parameters (e.g., elements of an array or record).
  • For runtime access, symbols have to be enclosed in quotation marks.
Example: 
mostAmsOutput(1, "AudioDiskPlayer.SourceActivity.StartResult(1,On)", 1);
testWaitForMostAMSMessage("AudioDiskPlayer.TrackPosition.Status(5)", 1, 200);
mostParamSet(msg, "Data.Record[].LastTrack", idx, 10);
