Container State Management via Lifecycle Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for managing state in parallel processing systems, such as locks and mutexes, require sophisticated programming skills and do not effectively handle conflicts when multiple processes update shared state simultaneously, leading to potential data loss.
Innovation Solution
A design time tool creates computer executable instructions that manage state for containers in a web client application based on their lifecycles, allowing for automatic handling of state creation, restoration, and teardown, and providing access to state based on lifecycle events, enabling unsophisticated developers to manage state without complex programming mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated programming mechanisms such as locks, mutexes, or critical sections are used to manage shared state in parallel processing systems, then conflicts between simultaneous updates are prevented, but the programming complexity and difficulty increase significantly
Solution Approach 1:
The patent segments the shared state into separate state variables associated with individual containers in a hierarchical structure. Each container has its own state that can be independently managed, eliminating the need for complex locking mechanisms to prevent conflicts. The state management is divided into discrete units that can be created, restored, and destroyed based on container lifecycles.
Solution Approach 2:
The patent introduces a design-time tool as an intermediary that automatically generates and manages state creation and destruction instructions. This mediator handles the complexity of state management behind the scenes, allowing developers to work with simple container hierarchies without directly implementing complex synchronization primitives.
2Ease of manufacture
If conventional state management methods are used in parallel processing systems, then implementation is simpler, but simultaneous updates to shared state can cause data loss when multiple processes update at the same time
Solution Approach 1:
The patent establishes state creation and destruction instructions in advance during design time, before the application runs. These pre-configured instructions automatically manage state based on container lifecycle events, preventing data loss from simultaneous updates without requiring complex runtime synchronization. The state management strategy is determined beforehand, simplifying implementation while ensuring data integrity.
3Reliability
If developers use sophisticated programming mechanisms to manage shared state, then state update conflicts are resolved, but the required programming skills and expertise increase
Solution Approach 1:
The patent enables the system to automatically manage state creation and destruction based on container lifecycles without requiring developers to manually implement complex synchronization logic. The design-time tool generates the necessary instructions, and the runtime system executes them automatically, making state management accessible to developers with basic skills while maintaining reliable conflict resolution.

AI summary
A hierarchy of containers is received at a user interface of a design time tool. The hierarchy of containers includes a container nested inside of one or more other containers. Each of the containers includes a different part of a web client application. The design time tool associates state with each of the containers in the hierarchy of containers. Lifecycles for each of the containers are received at the user interface. The design time tool creates computer executable instructions in the web client application that enable state for each of the containers to be created and destroyed according to the hierarchy based on the respective lifecycles of each of the containers. The design time tool provides each of the containers access to its own state and state of containers that include it based on respective lifecycle events associated with each of the containers.
