Solution Overview

Problem

Existing programming methodologies lack an efficient and user-friendly way to implement declarative programming styles, particularly in object-oriented languages, which limits flexibility and dynamic reconfiguration without access to application source code.

Innovation Solution

An attribute-based component programming system that dynamically generates program code based on declarative attributes, allowing for user-defined attributes and both static and dynamic code generation, enabling dynamic reconfiguration and improved productivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If declarative programming is implemented in object-oriented languages, then programming flexibility and dynamic reconfiguration are improved, but device complexity and implementation difficulty increase

Engineering Contradiction:
Improveprogramming flexibilityVSAvoidimplementation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a compiler intermediary that automatically translates declarative high-level programming constructs into low-level machine code. This mediator handles the complexity of declarative programming implementation, allowing programmers to write flexible, dynamic code without manually managing the underlying complexity. The compiler acts as the intermediary layer that resolves the contradiction between programming flexibility and implementation complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If dynamic code generation is implemented, then adaptability and reconfiguration capability are improved, but manufacturing precision and code reliability may worsen

Engineering Contradiction:
Improvedynamic reconfiguration capabilityVSAvoidcode generation precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent employs preliminary action by performing static analysis and code generation during the compilation phase before runtime execution. The compiler pre-generates code templates and validates declarative constructs during compilation, ensuring code precision and reliability before the program runs. This preliminary processing reduces uncertainties in dynamic code generation while maintaining adaptability at runtime.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If access to application source code is not required, then ease of operation and productivity are improved, but measurement precision and control capability worsen

Engineering Contradiction:
Improveoperational easeVSAvoidsource code analysis precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent uses copying by creating intermediate representations and abstract syntax trees that replicate the essential structure and semantics of the source code during compilation. These copied representations allow the compiler to perform precise analysis and translation without requiring direct access to or modification of the original source code files. This enables operational ease while maintaining measurement precision through accurate code modeling.

Inventive Principle:
Principle #26Copying

AI summary

An attribute-based component programming system and methodology for object-oriented languages is described. In one embodiment, for example, a method is described for dynamically generating program code adding behavior to a program based on attributes, the method comprises steps of: adding a component object to a program class of the program to create a component; defining at least one attribute specifying declaratively behavior to be added to the program; associating the at least one attribute with the component; and in response to instantiation of the component at runtime, generating a subclass based on the program class and the at least one attribute, the subclass including dynamically generated program code based on the at least one attribute.
