Runtime Proxy Generation for Isomorphic Interface Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In strongly typed languages like Java, subsystems require explicit knowledge of each other to interact, making it difficult for mutually indifferent subsystems to communicate at runtime without a common shared library, which introduces challenges in maintaining backward compatibility and can be error-prone.
Innovation Solution
A proxy mechanism that generates proxies for isomorphic interfaces at runtime, allowing subsystems to communicate transparently without a common shared library, by registering interfaces and simplifying method invocations through mechanisms like the Java Reflection API.

Engineering Contradiction Analysis
1Adaptability or versatility
If a common shared library is used to enable communication between subsystems with isomorphic interfaces, then subsystems can interact, but maintaining backward compatibility becomes difficult and error-prone
Solution Approach 1:
The patent introduces a proxy mechanism as an intermediary layer between subsystems with isomorphic interfaces. The proxy dynamically generates code at runtime to bridge interface incompatibilities, allowing subsystems to communicate without direct knowledge of each other while preserving backward compatibility. The proxy acts as a mediator that handles interface translation and method invocation without requiring a common shared library.
Solution Approach 2:
The patent employs dynamic code generation through the Java Reflection API to create proxies at runtime based on the actual interface structures. This dynamic approach allows the system to adapt to different interface versions and maintain compatibility without requiring static compilation-time knowledge or a fixed common library, thereby resolving the contradiction between adaptability and reliability.
2Reliability
If explicit knowledge of each other is required for subsystem interaction in strongly typed languages, then type safety is maintained, but mutually indifferent subsystems cannot communicate at runtime
Solution Approach 1:
The patent performs preliminary actions by dynamically generating proxy code at runtime that establishes the necessary type relationships between subsystems. The proxy is created in advance of actual method calls, setting up the type-safe interface bridging before communication occurs. This allows mutually indifferent subsystems to communicate while maintaining type safety through the generated proxy structure.
Solution Approach 2:
The proxy serves as an intermediary that maintains type safety by providing a type-safe interface to subsystems while handling the actual communication. The proxy encapsulates the type conversion and method invocation logic, allowing subsystems to interact with strong typing guarantees without requiring explicit knowledge of each other's interface structures.
3Adaptability or versatility
If the Java Reflection API is used for dynamic method invocation, then runtime flexibility is achieved, but the code becomes tedious and fragile
Solution Approach 1:
The patent extracts the complex Reflection API code from application logic and encapsulates it within the generated proxy class. The proxy internally handles all the tedious Reflection operations for method invocation and parameter passing, while presenting a simple, straightforward interface to the application developer. This separation removes the complexity from user code while preserving runtime flexibility.
Solution Approach 2:
The generated proxy performs self-service by automatically handling the complex Reflection API operations without requiring manual intervention from the developer. The proxy generates and executes the necessary Reflection code autonomously based on the interface definitions and method signatures, eliminating the need for developers to write fragile Reflection code while maintaining runtime flexibility.

AI summary
System and method for proxying isomorphic interfaces in different subsystems. Embodiments may provide a proxy mechanism that may generate proxies for isomorphic interfaces at runtime. Embodiments may allow two mutually indifferent subsystems to communicate with each other in a straightforward, transparent manner via proxies, without requiring a common shared library or complex coding. Embodiments of the proxy mechanism transparently generate proxies for isomorphic interfaces between subsystems in a virtual machine. In one embodiment, the application developer registers the interfaces that require proxying. The proxy mechanism then generates proxy instances. Methods may then be invoked, and the proxies handle the details of converting and forwarding the calls in accordance with the appropriate interface. Other subsystems, using different versions of the interface, may use the proxy mechanism to dynamically generate proxies without requiring extensive coding or shared libraries, and without interfering with other subsystems within the virtual machine.
