PI-Adapter

The PI-Adapter is used Commons Adapter Module to run Model with Adapter connected integrate with Delft-FEWS system.

How to work with PI-Adapter integrate to Delft-FEWS

The Delft-FEWS System run the workflow with model can be three parts:

• Pre Adapter: Convert Delft-FEWS export to the model input.
• Executable Adapter: Control the model executable process.
• Post Adapter: Convert model output to the Delft-FEWS import.

Three adapters through the Published Interface to synchronous communication with Delft-FEWS System.

Commons Adapter Module

The Commons Adapter Module's PiCommandLineExecute will receive the Delft-FEWS System pass information by standard arguments, so you can focus implements your adapter logic.

If you want see the fully integrate model example with PreAdapter, Executable Adapter and Post Adapter, please have a look at here.

The example implements code as blew:

public class ExamplePreAdapter extends PiCommandLineExecute {
    // Main process
    public static void main(String[] args) {
        PiIOArguments arguments = PiIOArguments.instance();
        new ExamplePreAdapter().execute( args, arguments );
    }
    
    @Override
    protected void adapterRun( PiBasicArguments arguments, 
        PiDiagnosticsLogger logger,
        Path basePath, Path inputPath, Path outputPath ) {
        PiIOArguments modelArguments = this.asIOArguments( arguments );
        // Your adapter logic
    }
}

The Model Folder Structure:

When start adapter with extends PiCommandLineExecute, program will check the model folder structure is follow the Delft-FEWS standard, the standard is show as below:

• Work/: The model main work folder.
  • Input/: The Delft-FEWS System exports place folder.
  • Output/: The Delft-FEWS System imports place folder.
  • Diagnostics/Diagnostics.xml: It's used to synchronous adaper logging message to Delft-FEWS System.

The Standard Arguments:

The arguments is extends from the BasicArguments:

• PiBasicArguments: - Basic arguments to run the command-Line interface, Not included input and output files, if you need this, use PiIOArguments please.

Argument	Description	Default	Required
-b / --base	The current working directory.	-	true
-h / --help	Show how to usage.	-	false
-id / --idir	The input file folder, relative to the current working directory.	Input/	false
-od / --odir	The output file folder, relative to the current working directory.	Output/	false
-ld / --ldir	The Pi Diagnostics log folder, relative to the current working directory.	Diagnostics/	false
-l / --log	The Pi Diagnostics log file name.	Diagnostics.xml	false
-t / --time	The T0. TimeZone is UTC.	-	false

• PiIOArguments: Standard arguments use for the included input, output files, parameter and unit to run the command-Line interface.

Argument	Description	Default	Required
-i / --input	The input file list with comma, and order is fixed.	-	true
-o / --output	The output file list with comma, and order is fixed.	-	true
-p / --parameter	The parameter name of model output, use only when program need it.	-	false
-u / --unit	The unit name of model output, use only when program need it.	-	false
