All Implemented Interfaces:

public class DefaultConfigurationWorker
extends ComponentManagerWorker

This Worker checks if certain OpenEMS-Components are configured and - if not - configures them. It is used to make sure a set of standard components are always activated by default on a deployed energy management system.

Example 1: Add JSON/REST-Api Controller by default:

 if (existingConfigs.stream().noneMatch(c -> //
 // Check if either "Controller.Api.Rest.ReadOnly" or
 // "Controller.Api.Rest.ReadWrite" exist
 "Controller.Api.Rest.ReadOnly".equals(c.factoryPid) || "Controller.Api.Rest.ReadWrite".equals(c.factoryPid))) {
        // if not -> create configuration for "Controller.Api.Rest.ReadOnly"
        this.createConfiguration(defaultConfigurationFailed, "Controller.Api.Rest.ReadOnly", Arrays.asList(//
                        new Property("id", "ctrlApiRest0"), //
                        new Property("alias", ""), //
                        new Property("enabled", true), //
                        new Property("port", 8084), //
                        new Property("debugMode", false) //
        ));
 }
 

Example 2: Add Modbus/TCP-Api Controller by default:

 if (existingConfigs.stream().noneMatch(c -> //
 // Check if either "Controller.Api.Rest.ReadOnly" or
 // "Controller.Api.Rest.ReadWrite" exist
 "Controller.Api.ModbusTcp.ReadOnly".equals(c.factoryPid)
                || "Controller.Api.ModbusTcp.ReadWrite".equals(c.factoryPid))) {
        // if not -> create configuration for "Controller.Api.Rest.ReadOnly"
        this.createConfiguration(defaultConfigurationFailed, "Controller.Api.ModbusTcp.ReadOnly", Arrays.asList(//
                        new Property("id", "ctrlApiModbusTcp0"), //
                        new Property("alias", ""), //
                        new Property("enabled", true), //
                        new Property("port", 502), //
                        new Property("component.ids", JsonUtils.buildJsonArray().add("_sum").build()), //
                        new Property("maxConcurrentConnections", 5) //
        ));
 }

Method Details

forever

protected void forever()

Description copied from class: AbstractWorker

This method is called in a loop forever until the Thread gets interrupted.

Specified by:

forever in class AbstractWorker

createConfiguration

protected void createConfiguration(AtomicBoolean defaultConfigurationFailed,
 String factoryPid,
 List<UpdateComponentConfigRequest.Property> properties)

Creates a Component configuration.

Parameters:

defaultConfigurationFailed - the result of the last configuration, updated on error

factoryPid - the Factory-PID

properties - the Component properties

updateConfiguration

protected void updateConfiguration(AtomicBoolean defaultConfigurationFailed,
 String componentId,
 List<UpdateComponentConfigRequest.Property> properties)

Updates a Component configuration.

Parameters:

defaultConfigurationFailed - the result of the last configuration, updated on error

componentId - the Component-ID

properties - the Component properties

deleteConfiguration

protected void deleteConfiguration(AtomicBoolean defaultConfigurationFailed,
 String componentId)

Deletes a Component configuration.

Parameters:

defaultConfigurationFailed - the result of the last configuration, updated on error

componentId - the Component-ID

getCycleTime

protected int getCycleTime()

Description copied from class: AbstractWorker

Gets the cycleTime of this worker in [ms].

• > 0 sets the minimum execution time of one Cycle
• = 0 never wait between two consecutive executions of forever()
• < 0 causes the Cycle to sleep forever until 'triggerNextRun()' is called

Specified by:

getCycleTime in class AbstractWorker

Returns:

the cycleTime
