NetKernel Foundation API

req=context.createSubRequest("active:httpResponseCodeFilter");
req.addArgument("operand", [resource representation, aspect, or URI] );
result=context.issueSubRequest(req);

Purpose

The httpResponseCodeFilter accessor is a filter which can be used to throw an exception for a non 200 HTTPResponseCodeAspect.

If the operand has an HTTPResponseCodeAspect and the Code is not 200 then a NetKernel Exception is thrown. If the representation does not have an HttpRespnseCodeAspect or the response code is 200 then the resource is returned unchanged.
