ActiveObject - util model method

[b]

Hi,

Is that possible to create method with nonpersistable field.

public interface A extends Entity {

    public void setB(String B);
    public String getB();

    public String doSth();
}

I want to for example, method doSth do additional operations like duplication of B object

You could use implementation classes as described in Implementing the Active Record Pattern to do additional operations like:

@Implementation(CompanyImpl.class)
public interface Company extends Entity {
	// ...
}

public class CompanyImpl {
	private Company company;
	
	public CompanyImpl(Company company) {
		this.company = company;
	}
	
	public void setName(String name) {
		company.setName(name);
		
		name = name.trim();
		if (name.length() > 4) {
			company.setTickerSymbol(name.substring(0, 4).toUpperCase());
		} else {
			company.setTickerSymbol(name.toUpperCase());
		}
	}
}

Hope this helps
