Provider client interface.

IJvDataConsumer is the main provider client interface. It is implemented by all components and controls that are able to obtain their information from a Data Provider.<br> <br> The interface only provides two "administrative" methods: retrieve the VCL component the consumer interface belongs to and determine which Data Provider Attributes apply to this consumer.<br> <br> Consumer may support additional interfaces (commonly referred to as "Consumer Extensions") to support other settings.<br> <br> Data Providers are generally not concerned about the consumer that is using them. The only notable exception is the ConsumerClasses method; this method will use the AttributeApplies method to determine which extensions are needed.<br> <br> Other cases when Data Providers are interested in the consumer are those providers that allow additional settings for each individual consumer (usually by providing a Provider specific Consumer<br> Extension).<br>
