In order to communicate with the framework the actual distributed application needs to use the JavaScript functions of the workunit interface contained in the file worker.js. These functions are
- js.input.read(name) — Reads the input corresponding to the given name
- js.work.setProgress(rate) — Reports the percentage of progress to the framework
- js.work.setCheckpoint(object) — Saves checkpoint data to the persistent storage
- js.work.getCheckpoint( ) — Retrieves the last checkpoint from the persistent storage
- js.work.debug(string) — Sends a debug message to the framework.
- js.output.write(name, string) — Writes the given data to the selected output stream
- js.output.writeLine(name, string) — Writes the given data with newline to the selected output stream
- js.evalJson(object) — Evaluates a JSON string and returns the corresponding object
- js.toJson(object) — Creates a JSON string from a given object
