Compiler Directive Parameter Management for Type Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing programming languages face challenges in managing function parameters with different data types, requiring multiple function versions and complex logic for type handling, which can lead to performance penalties and limitations in library development by third-party vendors without access to internal compiler tables.
Innovation Solution
A parameter management system using compiler directives populates a supplemental symbol-type dictionary with parameter data from source code, allowing substitution of specific function calls for generic ones and enforcing constraining conditions, enabling efficient type handling without hard-coded tables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple function versions are created to handle different data types, then type-specific functionality is improved, but device complexity and maintenance burden increase
Solution Approach 1:
The patent implements a single generic function that can handle multiple data types through type parameters and runtime type checking. Instead of creating separate function versions for each data type, the invention uses a universal function interface that adapts to different types through the typeof operator and conditional logic, thereby reducing complexity while maintaining versatility.
Solution Approach 2:
The patent introduces type parameters as additional function parameters that carry type information. By changing the parameter structure to include type descriptors (using typeof operator), the function can dynamically adapt its behavior based on the actual data type without requiring separate function definitions for each type.
2Ease of operation
If type-generic macros are used to mimic function overloading, then ease of operation is improved, but productivity decreases due to code intensity and performance penalties
Solution Approach 1:
The patent performs type detection and function selection during compile time using the typeof operator and compiler directives. By resolving type information beforehand rather than at runtime through macros, the invention eliminates the need for runtime type checking overhead while maintaining ease of operation, thus improving compilation efficiency and execution performance.
3Measurement precision
If compiler internal tables are accessed to detect function parameter types, then measurement precision is improved, but ease of manufacture deteriorates due to restricted library development
Solution Approach 1:
The patent introduces a public interface (typeof operator and compiler directives) that acts as an intermediary between the compiler's type detection capabilities and external library developers. This mediator provides precise type detection functionality without requiring access to internal compiler tables, enabling third-party vendors to develop type-safe libraries while maintaining accurate parameter type detection.
Data Source
AI summary
A method, system, architecture and apparatus for managing program function parameters using compiler directives. A parameter management system can include a compiler coupled to a primary symbol-type dictionary and a supplemental symbol-type dictionary containing parameter data for specific function calls of corresponding generic type functions. Notably, directive processing logic can be configured both to populate the supplemental symbol-type dictionary based upon processor directives embedded in source code, and also to substitute specific function calls for generic function calls in the source code as specified in the supplemental symbol-type dictionary.
