Query Evaluator Virtualizing Object Properties

The patent extracts only the necessary property values from objects rather than instantiating entire objects. The query evaluator identifies and retrieves only the specific properties required by the query, leaving the rest of the object structure uninstantiated. This directly addresses the contradiction by taking out only what is needed, improving query processing efficiency while reducing resource consumption.

The patent segments the object access process into two distinct phases: query evaluation (identifying needed properties) and object instantiation (creating only those specific properties). This segmentation allows the system to defer instantiation until necessary and only instantiate the required portions, thereby improving productivity while reducing energy loss from creating unnecessary object components.

The patent applies preliminary action by having the query evaluator identify and plan the exact properties needed before any object instantiation occurs. The query evaluation phase prepares a precise specification of required properties, which then guides the selective instantiation process. This preliminary planning eliminates wasted time on instantiating unnecessary object components, directly improving query processing speed while reducing time loss.

The patent implements partial action by instantiating only the specific properties required by the query rather than the entire object. The system performs exactly the amount of instantiation needed—no more, no less—thereby optimizing query processing speed while minimizing the time spent on object creation. This partial action approach directly addresses the time loss problem proportional to object size.
