MessageHandler.Partial (Jakarta WebSocket API documentation)

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.
