io.github.a2ap.core.server.impl.InMemoryQueueManager
所有已实现的接口:
QueueManager
public class InMemoryQueueManager extends Object implements QueueManager
In-memory implementation of QueueManager for managing task event queues. This implementation manages EventQueue instances for tasks using a thread-safe ConcurrentHashMap. It provides the core functionality for creating, accessing, and managing event queues that facilitate streaming communication between agents and clients in the A2A protocol. Key features: - Thread-safe queue management using ConcurrentHashMap - Support for queue creation and retrieval by task ID - Queue tapping functionality for creating child queues - Automatic cleanup when queues are removed - Comprehensive logging for debugging and monitoring Queue lifecycle: 1. create() - Creates a new EventQueue for a task (idempotent) 2. get() - Retrieves an existing queue without creating 3. tap() - Creates a child queue that receives the same events 4. remove() - Removes and closes the queue, cleaning up resources This implementation is suitable for single-instance deployments and provides the foundation for streaming task updates and real-time communication in the A2A protocol. For distributed deployments, consider implementing QueueManager with a distributed messaging system.
