Concise Expression Classes for Interpreted Languages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In interpreted object-oriented programming languages, there is no pre-processor to check if all components of a program exist before runtime, making it difficult to ensure that required data and functions are available, leading to complex and error-prone code expressions.
Innovation Solution
The introduction of concise expression classes that include operator overloading to return an instance of a void object when data or objects do not exist, allowing expressions to be executed without crashing the software application by ensuring non-existent objects do not cause errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive testing constructs are used to check for existence of data and functions, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary existence-checking mechanism that automatically verifies whether data or functions exist before execution. This mediator handles the complexity of existence checks internally, allowing the main code to remain simple while reliability is maintained through automatic checking.
Solution Approach 2:
The patent performs existence checks preliminarily before the actual code execution. By checking for the existence of data and functions in advance and preparing appropriate handling strategies, the system ensures reliable execution without requiring extensive testing constructs within the main code flow.
2Reliability
If pre-processor macros are used to embed tests, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent extracts the complexity of existence checking and test embedding from the main code into separate pre-processor mechanisms and runtime checking systems. This allows the main code to maintain high readability while reliability is ensured through the extracted checking logic that operates transparently in the background.
3Ease of operation
If no pre-processor is used in interpreted languages, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The patent introduces an intermediary runtime checking system that operates in interpreted languages without requiring a pre-processor. This mediator automatically checks for the existence of data and functions during execution, maintaining code simplicity while ensuring reliability through transparent existence verification.

AI summary
A method and apparatus for the concise expression of optional code snippets in interpreted object-oriented programming language software applications is described. In one embodiment, the method includes defining a first class where the first class is a concise expression class that includes one or more objects. The method may also include including the concise expression class in a second class that includes one or more objects of the second class. The method may also include executing an expression in a software application to evaluate an object of the second class and returning an instance of an object of the concise expression class when data associated with the object of the second class does not exist within the software application.
