Interface MessageChannel

All Superinterfaces:

public interface MessageChannel
extends Channel, Formattable

Represents a Discord channel that can have Messages and files sent to it.

Formattable
This interface extends Formattable and can be used with a Formatter such as used by String.format(String, Object...) or PrintStream.printf(String, Object...).

This will use Channel.getName() rather than Object.toString()!
Supported Features:

• Alternative
  - Prepends the name with # (Example: %#s - results in #Channel.getName())
• Width/Left-Justification
  - Ensures the size of a format (Example: %20s - uses at minimum 20 chars; %-10s - uses left-justified padding)
• Precision
  - Cuts the content to the specified size (Example: %.20s)

More information on formatting syntax can be found in the format syntax documentation!
GuildMessageChannel is a special case which uses IMentionable.getAsMention() by default and uses the #Channel.getName() format as alternative

• TextChannel

Method Details

getLatestMessageId

@Nonnull
default String getLatestMessageId()

The id for the most recent message sent in this current MessageChannel.

This value is updated on each MessageReceivedEvent and the value might point to an already deleted message since the ID is not cleared when the message is deleted, so calling retrieveMessageById(long) with this id can result in an UNKNOWN_MESSAGE error

Returns:

The most recent message's id or "0" if no messages are present

getLatestMessageIdLong

long getLatestMessageIdLong()

The id for the most recent message sent in this current MessageChannel.

This value is updated on each MessageReceivedEvent and the value might point to an already deleted message since the value is not cleared when the message is deleted, so calling retrieveMessageById(long) with this id can result in an UNKNOWN_MESSAGE error

Returns:

The most recent message's id or 0 if no messages are present

canTalk

boolean canTalk()

Whether the currently logged in user can send messages in this channel or not.
For GuildMessageChannel this method checks for both Permission.VIEW_CHANNEL and Permission.MESSAGE_SEND.
For ThreadChannel this method checks for Permission.MESSAGE_SEND_IN_THREADS instead of Permission.MESSAGE_SEND.
For PrivateChannel this method checks if the user that this PrivateChannel communicates with is not a bot, but it does not check if the said user blocked the currently logged in user or have their DMs disabled.

Returns:

True, if we are able to read and send messages in this channel

sendFiles

@Nonnull
@CheckReturnValue
default MessageCreateAction sendFiles(@Nonnull
 Collection<? extends FileUpload> files)

Send a message to this channel.

Resource Handling Note: Once the request is handed off to the requester, for example when you call RestAction.queue(), the requester will automatically clean up all opened files by itself. You are only responsible to close them yourself if it is never handed off properly. For instance, if an exception occurs after using FileUpload.fromData(File), before calling RestAction.queue(). You can safely use a try-with-resources to handle this, since FileUpload.close() becomes ineffective once the request is handed off.

Possible ErrorResponses include:

• UNKNOWN_CHANNEL
  if this channel was deleted
• CANNOT_SEND_TO_USER
  If this is a PrivateChannel and the currently logged in account does not share any Guilds with the recipient User
• MESSAGE_BLOCKED_BY_AUTOMOD
  If this message was blocked by an AutoModRule
• MESSAGE_BLOCKED_BY_HARMFUL_LINK_FILTER
  If this message was blocked by the harmful link filter
• REQUEST_ENTITY_TOO_LARGE
  If the total sum of uploaded bytes exceeds the guild's upload limit

Example: Attachment Images

 // Make a file upload instance which refers to a local file called "myFile.png"
 // The second parameter "image.png" is the filename we tell discord to use for the attachment
 FileUpload file = FileUpload.fromData(new File("myFile.png"), "image.png");

 // Build a message embed which refers to this attachment by the given name.
 // Note that this must be the same name as configured for the attachment, not your local filename.
 MessageEmbed embed = new EmbedBuilder()
   .setDescription("This is my cute cat :)")
   .setImage("attachment://image.png") // refer to the file by using the "attachment://" schema with the filename we gave it above
   .build();

 channel.sendFiles(Collections.singleton(file)) // send the file upload

getIterableHistory

@Nonnull
@CheckReturnValue
default MessagePaginationAction getIterableHistory()

A PaginationAction implementation that allows to iterate over recent Messages of this MessageChannel.

It is recommended not to use this in an enhanced for-loop without end conditions as it might cause memory overflows in channels with a long message history.

Examples

 public CompletableFuture<List<Message>> getMessagesByUser(MessageChannel channel, User user) {
     return channel.getIterableHistory()
         .takeAsync(1000) // Collect 1000 messages
         .thenApply(list ->
             list.stream()
                 .filter(m -> m.getAuthor().equals(user)) // Filter messages by author
                 .collect(Collectors.toList())
         );
 }

Attempts to edit a message by its id in this MessageChannel.

The following ErrorResponses are possible:

• REQUEST_ENTITY_TOO_LARGE
  If any of the provided files is bigger than Guild.getMaxFileSize()
• INVALID_AUTHOR_EDIT
  Attempted to edit a message that was not sent by the currently logged in account. Discord does not allow editing of other users' Messages!

Resource Handling Note: Once the request is handed off to the requester, for example when you call RestAction.queue(), the requester will automatically clean up all opened files by itself. You are only responsible to close them yourself if it is never handed off properly. For instance, if an exception occurs after using FileUpload.fromData(File), before calling RestAction.queue().

editMessageAttachmentsById

@Nonnull
@CheckReturnValue
default MessageEditAction editMessageAttachmentsById(long messageId,
 @Nonnull
 AttachedFile... attachments)

Attempts to edit a message by its id in this MessageChannel.

The following ErrorResponses are possible:

• REQUEST_ENTITY_TOO_LARGE
  If any of the provided files is bigger than Guild.getMaxFileSize()
• INVALID_AUTHOR_EDIT
  Attempted to edit a message that was not sent by the currently logged in account. Discord does not allow editing of other users' Messages!
• MISSING_ACCESS
  The request was attempted after the account lost access to the Guild typically due to being kicked or removed, or after Permission.VIEW_CHANNEL was revoked in the GuildMessageChannel
• UNKNOWN_MESSAGE
  The provided messageId is unknown in this MessageChannel, either due to the id being invalid, or the message it referred to has already been deleted. This might also be triggered for ephemeral messages.
• UNKNOWN_CHANNEL
  The request was attempted after the channel was deleted.

Resource Handling Note: Once the request is handed off to the requester, for example when you call RestAction.queue(), the requester will automatically clean up all opened files by itself. You are only responsible to close them yourself if it is never handed off properly. For instance, if an exception occurs after using FileUpload.fromData(File), before calling RestAction.queue(). You can safely use a try-with-resources to handle this, since FileUpload.close() becomes ineffective once the request is handed off.

Parameters:

messageId - The message id. For interactions this supports "@original" to edit the source message of the interaction.

attachments - The new attachments of the message (Can be FileUploads or AttachmentUpdates)
