Class ChatPreviewer

java.lang.Object
net.minecraft.client.network.ChatPreviewer
@Environment(CLIENT) public class ChatPreviewer extends Object
Chat previewer manages the chat preview. Chat previewer is created per ChatScreen, so closing the chat screen and reopening it would create a new chat previewer. ChatPreviewRequester handles the actual requesting.

The response to the query can be "consumed" by calling tryConsumeResponse(java.lang.String). If the response is still valid (i.e. the input has not changed since the query was sent), consuming the response will return the response and clear it. Note that to prevent race condition between the player sending the chat message and the response's arrival, responses can only be consumed after the cooldown (by default, 200L milliseconds) has passed. It is also possible to get the response text without consuming by calling getPreviewText().
