Generic Callback Handling Framework Registry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing callback handling systems in software applications, particularly in GUI development, are error-prone and resource-intensive when dealing with large numbers of components and callbacks, leading to inefficiencies in event handling and computing resource usage.
Innovation Solution
A framework for generic callback handling that registers components with a specific context and associated callbacks, allowing a single trigger to invoke all registered callbacks under that context, eliminating the need for iterative component traversal and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If callbacks are handled by iterating through components at the trigger point, then all callbacks can be triggered, but the system becomes error-prone and consumes more computing resources
Solution Approach 1:
The patent applies preliminary action by pre-registering all callback handlers with the framework before events occur. During registration, handlers are stored in a structured registry organized by event types and targets. This eliminates the need for runtime iteration through components, as the system directly invokes pre-registered handlers when events are triggered, reducing both errors and computing resource consumption
Solution Approach 2:
The patent introduces a callback framework as an intermediary layer between event sources and handlers. This framework maintains a registry that maps events to their corresponding handlers, acting as a mediator that receives events and automatically routes them to the appropriate pre-registered handlers without requiring direct iteration or complex component traversal
2Reliability
If callbacks are handled by iterating through components at the trigger point, then all callbacks can be triggered, but the process becomes more complex and error-prone
Solution Approach 1:
The framework performs preliminary registration of all callback handlers during system initialization or component registration phases. Handlers are stored in a structured registry with clear associations to their target components and event types. When events occur, the system simply looks up and invokes the pre-registered handlers, eliminating complex runtime iteration logic and reducing errors
Solution Approach 2:
The callback framework serves as an intermediary that manages the complexity of callback handling. It maintains a centralized registry that automatically tracks which handlers should respond to which events, replacing complex iterative component traversal with simple lookup and invocation operations
3Productivity
If a single trigger invokes all registered callbacks centrally, then resource consumption is reduced, but the framework requires complex registration and management structures
Solution Approach 1:
The patent implements a universal callback framework that handles multiple event types and component kinds through a single unified registration and invocation mechanism. The framework's registry structure and trigger handling logic are general-purpose, working with any event-target-handler combination without requiring specialized code paths, thereby achieving high efficiency without proportionally increasing complexity
Data Source
AI summary
A framework for generically handling callbacks is described herein. In accordance with one aspect, multiple components or data objects are registered. The registration of a component includes providing a context name and one or more callbacks. A callback of each registered component references to the component and is registered under a context. A trigger may be invoked in response to receiving an event, where a context is provided to the trigger based on the event. A set of callbacks that are registered under the context are then triggered. The triggered callbacks reference to components registered under the context.
