Dynamic Type Generation via Template Method Cloning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emitting code at runtime for dynamic types is currently difficult, time-consuming, and error-prone, requiring developers to manually write procedures in low-level languages that are then compiled into assemblies, making it cumbersome to generate complex functions and modify existing code.
Innovation Solution
A process that clones a previously compiled method, injecting custom code at marked locations to alter its behavior, and compiling the resulting dynamic code, which reduces complexity and error by leveraging a compiler-generated template method.

Engineering Contradiction Analysis
1Productivity
If developers manually write procedures in low-level languages to emit code at runtime for dynamic types, then code generation is possible, but the process becomes difficult, time-consuming, and error-prone
Solution Approach 1:
The patent applies preliminary action by pre-compiling template methods into assembly code before runtime needs them. These template methods contain placeholder instructions that will be replaced with custom code later. This preparation work is done in advance, so when dynamic code generation is needed at runtime, the system only needs to perform simple substitution operations rather than generating entire procedures from scratch in low-level languages.
Solution Approach 2:
The patent uses copying by creating clones of pre-compiled template methods. Instead of manually writing new low-level procedures each time dynamic code is needed, the system copies existing template method structures and injects custom logic into them. This copying approach reuses proven, compiler-optimized code frameworks while allowing customization, dramatically reducing the effort and error rate compared to manual low-level programming.
2Adaptability or versatility
If developers manually write procedures in low-level languages to emit code at runtime, then dynamic type code can be generated, but the process becomes cumbersome and error-prone
Solution Approach 1:
The patent introduces an intermediary layer consisting of template methods that act as mediators between the high-level customization needs and the low-level assembly code requirements. Developers work with high-level template definitions and customization parameters rather than directly writing assembly instructions. The template system automatically handles the translation and injection processes, providing an intermediary interface that is both adaptable to different customization needs and easy to operate.
3Ease of manufacture
If pre-compiled template methods are cloned and custom code is injected, then code generation is simplified, but compilation time may increase
Solution Approach 1:
The patent applies preliminary action by performing the complex compilation work in advance when template methods are created, rather than at runtime when they are needed. The template methods are pre-compiled into assembly with placeholder instructions during the development phase. At runtime, only simple code injection and final linking operations are required, which are much faster than full compilation. This shifts the time investment to when it doesn't impact performance-critical operations.
