Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer programs lack the ability to adapt to different circumstances without modifying the underlying code, making it difficult to address changes in variables or expressions, particularly for debugging purposes.
Innovation Solution
A data processing apparatus and method that receives source code and watch modification instructions, using abstract syntax trees to identify and apply modifications at specific locations in the code where variables or expressions may change, allowing for precise and efficient code transformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the underlying code is modified to work under different circumstances, then the program can adapt to different environments, but the original code structure and functionality are altered
Solution Approach 1:
The patent segments the code modification process by introducing a separate transformation layer that operates on the original code without altering it. The original code remains intact while a transformation module applies modifications selectively, allowing adaptability without compromising the stability of the original code structure.
Solution Approach 2:
The patent introduces an intermediary transformation module that acts as a mediator between the original code and the modified code. This intermediary applies watch modification instructions to generate adapted code without directly modifying the original code, thus maintaining code structure stability while achieving program adaptability.
2Reliability
If modifications are applied to multiple locations in source code, then comprehensive debugging coverage is achieved, but the complexity of managing modifications increases
Solution Approach 1:
The patent creates a universal watch modification instruction format that can target multiple locations in source code simultaneously. The transformation module processes these instructions uniformly, applying the same modification pattern across different locations, which simplifies the management of comprehensive debugging coverage while maintaining high reliability.
Solution Approach 2:
The patent uses parameter-based watch modification instructions that specify target locations and modification patterns separately. By changing parameters such as variable names, expression patterns, and location specifications, the system can efficiently manage modifications across multiple locations without increasing overall system complexity.
3Measurement precision
If watch modification instructions are used to track variable changes, then debugging precision is improved, but the time required to analyze and apply modifications increases
Solution Approach 1:
The patent performs preliminary parsing and analysis of source code to pre-identify potential variable change locations and expressions. By preparing the code structure in advance and organizing it into an abstract syntax tree, the system reduces the time required to analyze and apply watch modification instructions while maintaining high debugging precision.
Solution Approach 2:
The patent replaces manual code analysis with automated transformation circuitry that uses pattern matching and abstract syntax tree traversal. This substitution of mechanical analysis with automated processing significantly reduces the time required to analyze and apply modifications while preserving precise debugging capabilities.
Data Source
AI summary
A data processing apparatus includes source input circuitry that receives source code. Modification input circuitry receives a watch modification instruction that indicates an expression or variable, and a modification to be made to the source code at one or more locations in the source code where the expression or variable could change. Processing circuitry applies the modification to the one or more locations in the source code.
