Package jakarta.websocket

Interface MessageHandler.Partial<T>

Type Parameters:

T - The type of the object that represent pieces of the incoming message that this MessageHandler will consume.

All Superinterfaces:

MessageHandler

Enclosing interface:

MessageHandler

public static interface MessageHandler.Partial<T>
extends MessageHandler

This kind of handler is notified by the implementation as it becomes ready to deliver parts of a whole message.

For handling parts of text messages, the type T is String

For handling parts of binary messages, the allowable types for T are

• ByteBuffer
• byte[]

Developers should not continue to reference message objects of type ByteBuffer after the completion of the onMessage() call, since they may be recycled by the implementation.

Note: Implementations may choose their own schemes for delivering large messages in smaller parts through this API. These schemes may or may not bear a relationship to the underlying websocket dataframes in which the message is received off the wire.
