## Interface MessageHandler.Whole<T>

- Type Parameters:
    `T` - The type of the message object that this MessageHandler will consume.
  All Superinterfaces:
    MessageHandler
  Enclosing interface:
    MessageHandler

      public static interface MessageHandler.Whole<T>
      extends MessageHandler

  This kind of handler is notified by the container on arrival of a complete message. If the message is received in parts, the container buffers it until it is has been fully received before this method is called.

  For handling incoming text messages, the allowed types for T are

  - `String`
  - `Reader`
  - any developer object for which there is a corresponding `Decoder.Text` or `Decoder.TextStream` configured

  For handling incoming binary messages, the allowed types for T are

  - `ByteBuffer`
  - byte[]
  - `InputStream`
  - any developer object for which there is a corresponding `Decoder.Binary` or `Decoder.BinaryStream` configured

  For handling incoming pong messages, the type of T is `PongMessage`

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