Workunit API

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.evalJson( object ) — Evaluates a JSON string and returns the corresponding object
• js.toJson( object ) — Creates a JSON string from a given object
• 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.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.
