Interface MessageDecorator

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface MessageDecorator
Message decorator decorates the chat messages and other messages server-side. Currently, only one message decorator can exist at a time. The message decorator that is currently used can be obtained by MinecraftServer.getMessageDecorator().

For the message decorator to produce a signed message, both the server and the sender's client need to have chat previews enabled, Otherwise, the decorated content is considered unsigned, and if the clients require chat messages to be signed via the "Only Show Secure Chat" option, they will see the undecorated message. Therefore, message decorator is not recommended for censoring messages.

It is very important that the decorator be idempotent; i.e. return the same text when given the same text (and sender). If this is not followed correctly, the server will discard the message. For example, a decorator that appends the time the decoration was applied would be likely to fail, since there is usually a delay between the previewing and the submission.

    • decorate

      CompletableFuture<Text> decorate(@Nullable @Nullable ServerPlayerEntity sender, Text message)
      Returns the decorated message.
      Parameters:
      sender - the player who sent the message, or null if message was not sent by a player
      Returns:
      the decorated message

    • decorateFiltered

      default CompletableFuture<FilteredMessage<Text>> decorateFiltered(@Nullable @Nullable ServerPlayerEntity sender, FilteredMessage<Text> message)
      Returns the decorated filtered message from undecorated message.

      This keeps the filtered status of the original message; i.e. fully censored messages will remain fully censored, and unfiltered messages will remain unfiltered. If the message is partially filtered, both the raw and the filtered message will be decorated.

      Returns:
      the decorated filtered message from undecorated message

      named decorateFiltered Lnet/minecraft/network/message/MessageDecorator;decorateFiltered(Lnet/minecraft/server/network/ServerPlayerEntity;Lnet/minecraft/server/filter/FilteredMessage;)Ljava/util/concurrent/CompletableFuture;

    • decorateChat

      default CompletableFuture<FilteredMessage<SignedMessage>> decorateChat(@Nullable @Nullable ServerPlayerEntity sender, FilteredMessage<Text> message, MessageSignature signature, boolean previewed)
      Returns the decorated signed chat message from undecorated message.

      If previewed is false, the returned message will have the original content as signed and the decorated content as unsigned. This means that if the received player requires signed chat message, they will see the original content.

      This keeps the filtered status of the original message; i.e. fully censored messages will remain fully censored, and unfiltered messages will remain unfiltered. If the message is partially filtered, both the raw and the filtered message will be decorated.

      Parameters:
      previewed - whether the decoration was previewed by the sender's client
      Returns:
      the decorated signed chat message from undecorated message
