NF9 OSGi New Column Callout Factory

From iDempiere en

Feature: OSGi New Column Callout Factory

Goal: Development

Developer: Hengsin (talk)

Description:

  • Implement a new column callout factory base class that's backed by Map and Lambda functional object.
  • Implement callout annotation and factory base class that scan and register classes with callout annotation.


Usage:
With following Callout class:

public class MyTestAmountCallout implements IColumnCallout {
    @Override
    public String start(Properties ctx, int WindowNo, GridTab mTab, GridField mField, Object value, Object oldValue) {
        return null;
    }		
}

Developer can use one of the following approach:

1. At plugin Activator start method, register the callout class.

public void start(BundleContext context) throws Exception {
    var factory = Core.getMappedColumnCalloutFactory();
    factory.addMapping(MTest.Table_Name, MTest.COLUMNNAME_T_Amount, () -> new MyTestAmountCallout());
}

2. Create an osgi component, at the bind method for the IMappedColumnCalloutFactory service.

public void bindService(IMappedColumnCalloutFactory factory) {
    factory.addMapping(MTest.Table_Name, MTest.COLUMNNAME_T_Amount, () -> new MyTestAmountCallout());
}

3. Create a subclass of MappedColumnCalloutFactory, register as IColumnCalloutFactory service (DO NOT register as IMappedColumnCalloutFactory service).

public class MyFactory extends MappedColumnCalloutFactory {
    public MyFactory() {
	addMapping(MTest.Table_Name, MTest.COLUMNNAME_T_Amount, () -> new MyTestAmountCallout());
    }
}

Annotation:

  1. org.adempiere.base.annotation.Callout with tableName and columnName parameter. Use '*' to match any table or column name.
  2. Usage: Annotate your class with org.adempiere.base.annotation.Callout annotation and create an OSGi component that extends the AnnotationBasedColumnCalloutFactory class (with service = IColumnCalloutFactory.class).


 @Callout(tableName = "AD_InfoWindow", columnName = "AD_Table_ID")
 @Callout(tableName = "AD_InfoColumn", columnName = {"AD_Element_ID","AD_Reference_ID"})
 public class CalloutInfoWindow implements IColumnCallout {
     @Override
     public String start(Properties ctx, int WindowNo, GridTab mTab, GridField mField, Object value, Object oldValue) {
        ...
     }
 }
