TROCustomRODLReader

Overview

This is an abstract class to allow RODL reading process to be customized. Such customization is an advanced technique that can be used by either server class or message class or both. RODL reading customization may be necessary if the RODL content access is more complex then just reading a local resource. For example, Hydra enabled applications may consist of several modules and each of those may contain its own RODL resource.
In general this feature is rarely used. The RemoObjects SDK itself has no concrete TROCustomRODLReader descendants implemented, just serving as a base for extensions.
