socketio/socket.io-client-java

Features

• Real-Time Connections - Building Java applications that exchange instant data with a server using event-driven updates and low-latency connections.
• Socket.IO Client Libraries - Implements the Socket.IO protocol to enable real-time bidirectional communication between Java applications and servers.
• Bidirectional Socket Communication - Facilitates simultaneous bidirectional reading and writing of event-based data between the client and server.
• Event-Driven Communication Clients - Provides an event-driven client for exchanging named events and binary data with a remote server.
• Event Emission Systems - Enables sending named events with serializable arguments or binary data to a remote server.
• Transport Abstraction Layers - Provides a unified interface that abstracts the differences between WebSocket and long-polling transports.
• WebSocket and HTTP Fallback Transports - Provides transparent switching between WebSocket and HTTP long-polling transports while preserving session identity.
• Real-Time Event Handlers - Implements application logic that triggers specific callbacks in response to real-time server events.
• Client-Side Event Listeners - Allows registering client-side callback functions that trigger when specific events are emitted by the server.
• Socket.IO Client Implementations - Provides a complete Java client implementation of the Socket.IO protocol for real-time event handling.
• WebSocket Clients - Implements bidirectional WebSocket connections over HTTP for continuous, low-latency data streaming.
• Namespace-Based Communication - Logically partitions communication channels to isolate traffic and modules within a single physical connection.
• WebSocket and Fallback Connection Establishment - Implements the initial handshake process with automatic fallback from WebSocket to HTTP long-polling.
• Connection Handshake Protocols - Manages the negotiation of configuration and session identifiers during the initial connection establishment.
• Connection Multiplexing - Enables bundling multiple logical data streams into a single physical connection using namespaces.
• Namespace Multiplexing - Isolates communication channels on a single socket using named namespaces to separate event handlers.
• Connection Lifecycle Managers - Provides callbacks to manage state transitions, heartbeats, and reconnection logic for persistent user sessions.
• Packet Serialization Frameworks - Encapsulates structured data and metadata into binary packets for consistent bidirectional transmission.
• Long-Polling Event Pushing - Implements a fallback mechanism that uses long-polling to push events when WebSockets are unavailable.
• Credentials Object Authentications - Allows passing authentication tokens or credentials during the connection handshake to verify client identity.
• TLS/SSL Configurations - Manages secure connections through custom keystores, hostname verifiers, and TLS/SSL configurations.
• Client Acknowledgment Callbacks - Implements request-response patterns using callback functions that trigger upon server confirmation of receipt.
• Event-Driven Callbacks - Maps specific event names to executable functions that trigger automatically upon packet arrival.
