Shared resource
A shared resource is data, an object, or another resource that multiple people, components, or execution contexts can access or use.
Grokking Concurrency
A shared object is a data or resource object accessed by multiple concurrent execution threads.
- How it is used
- Enables threads or concurrent tasks to exchange data through shared memory or storage.
- How deep it goes
- Explains access hazards, synchronization costs, and alternatives, but does not provide synchronization implementation steps.
- Examples
- Uses a process address space shared by threads and a NAS volume for MapReduce intermediate data.
- What you can do after
- Evaluate when shared data needs synchronization and when message passing could avoid shared memory.
Modern C, Third Edition
A shared object is an object whose storage and value can be accessed by more than one thread.
- How it is used
- Coordinates initialization, access, protection, and destruction when multiple threads use the same object.
- How deep it goes
- Explains initialization ordering, one-time initialization, cleanup, and protection choices, but does not develop memory-model internals.
- Examples
- Demonstrates a shared error log initialized with call_once and finalized through atexit or at_quick_exit handlers.
- What you can do after
- Operate shared C objects safely by ordering initialization, guarding one-time setup, protecting critical sections, and arranging cleanup.
Pro Angular 16
A shared object is an object instance made available to multiple application components so they can access common state or behavior.
- How it is used
- Coordinates common discount state and behavior between Angular components in a product-table application.
- How deep it goes
- Explains object creation, input passing, getters, setters, and two-way binding, but stops short of service injection.
- Examples
- Uses DiscountService, a discount editor, a discount display, and a product-table template.
- What you can do after
- Build shared component state by creating one object and passing it through Angular input properties.
