Enhancement(?): Subclassed "IDACall"-equivalent for serverside requests

[Blama]

Hello Isomorphic,

is it possible to do something similar like subclassing IDACall on the server side?
I managed to add criteria to all my client side requests using the code shown in http://forums.smartclient.com/showpo...96&postcount=4.

Now all the requests coming from the browser have the criteria I want. Is there something similar possible for the serverside, e.g. overwrite the default implementations for fetch, update, remove and add, when there is no ServerObject given?

Right now I found out that it is better to move the code I have in my IDACall in a separate static method class and use that from all my ds.xml with a ServerObject like:
ds.xml:

	.....
	<serverObject lookupStyle="new" className="com.lmscompany.lms.server.worker.T_LEADTEMPERATURE" />
	<operationBindings>
	</operationBindings>
</DataSource>

LEADTEMPERATURE.java:

public class T_LEADTEMPERATURE {
	public DSResponse fetch(DSRequest dsRequest, HttpServletRequest servletRequest) throws Exception {
		RequestModifier.modifyCriteria(dsRequest, servletRequest);
		return dsRequest.execute();
	}
};

RequestModifier.modifyCriteria() adds the criteria needed. I'd now add a ds-specific <serverObject> to every DS and overwrite fetch() there every time with boilerplate code. Even if I called a generic ServerObject-class from every DS, I'd still need the <serverObject>-tag in every .ds.xml.

Is it already possible to pre-process all requests by one "per application"-ServerObject, before the ds.xml-processing starts or might this be a good enhancement idea?

Best regards,
Blama

PS: Even if it's not possible, I still can solve my use-cases with so little code - perfect! Thank you, once again.

Take a look at the ability to create a Custom DataSource via the serverConstructor attribute (see QuickStart Guide, search for "Custom DataSource").

Your custom DataSource can be a subclass of SQLDataSource that you use in every .ds.xml file - this gives you the ability to add special behaviors to any operation on all of your DataSources, without needing the entire <operationBinding><serverObject> structure on each one.

Hi Isomorphic,

thanks for the pointer. It works exactly as expected.
