02_buffer Project Overview

The 02_buffer project demonstrates how to manage a Shared Buffer in a multithreaded environment with the AREG framework. This example illustrates initializing a shared buffer, performing write and read operations, and efficiently streaming data between threads. In the AREG framework, the Shared Buffer facilitates data transfer by creating hard copies of primitives and objects in each thread, rather than synchronizing shared memory access.

Note

SharedBuffer is not designed for synchronized, concurrent data sharing in a multithreaded environment. Since it does not lock data access, simultaneous writes from multiple threads can yield unpredictable results. SharedBuffer is intended to transfer data copies from one thread to another, rather than synchronize shared data access.

Key Concepts

• Shared Buffer: See how to initialize and manage a shared buffer that transfers data values from one thread to multiple others, without synchronized data locking.
• Multithreading: Understand the flow of primitive and object data between threads, achieving efficient data sharing without concurrent resource locking.
• Thread Management: Uses the Thread class and IEThreadConsumer interface to manage thread lifecycles and coordinate activities.

Features

• Buffer Initialization: Learn how to initialize a Shared Buffer for safe data storage and transport across threads.
• Read and Write Operations: Explore how threads perform serialized read and write operations on the buffer, with clear data flow between threads.
• Data Streaming: See how data is serialized into and deserialized from the buffer, demonstrating straightforward data streaming.

Project Structure

• Shared Buffer: The SharedBuffer class, with a reference counter, prevents buffer release while in use by multiple threads.
• Thread Management: The Thread class and IEThreadConsumer interface enable smooth thread creation and interaction with the shared buffer.
• Data Flow: Demonstrates efficient data streaming from one thread to others using the buffer.

Use Cases

• Multithreaded Applications: Suitable for applications that require copying data between threads rather than synchronizing data access.
• Inter-Thread Communication: Facilitates straightforward data exchange between threads.
• Real-Time Data Processing: Ideal for scenarios requiring rapid, multi-threaded data distribution without shared memory conflicts.

Conclusion

The 02_buffer project is a practical guide to implementing inter-thread data streaming in a multithreaded environment with the AREG framework, emphasizing efficient data transfer without synchronization.
