Interface MessageChannel

All Superinterfaces:

Channel, Formattable, IMentionable, ISnowflake

All Known Subinterfaces:

BaseGuildMessageChannel, GuildMessageChannel, NewsChannel, PrivateChannel, TextChannel, ThreadChannel

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!
TextChannel is a special case which uses IMentionable.getAsMention() by default and uses the #Channel.getName() format as alternative

Method Details

getLatestMessageId

@Nonnull
default String getLatestMessageId()

The id for the most recent message sent in this current MessageChannel.
This should only be used if hasLatestMessage() returns true!

This value is updated on each MessageReceivedEvent and will be reset to null if the message associated with this ID gets deleted

Returns:

The most recent message's id

Throws:

IllegalStateException - If no message id is available

getLatestMessageIdLong

long getLatestMessageIdLong()

The id for the most recent message sent in this current MessageChannel.
This should only be used if hasLatestMessage() returns true!

This value is updated on each MessageReceivedEvent and will be reset to null if the message associated with this ID gets deleted

Returns:

The most recent message's id

Throws:

IllegalStateException - If no message id is available

hasLatestMessage

default boolean hasLatestMessage()

Whether this MessageChannel contains a tracked most recent message or not.

This does not directly mean that getHistory() will be unable to retrieve past messages, it merely means that the latest message is untracked by our internal cache meaning that if this returns false the getLatestMessageId() method will throw an NoSuchElementException

Returns:

True, if a latest message id is available for retrieval by getLatestMessageId()

See Also:

• getLatestMessageId()

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.

 @Nonnull
 AttachmentOption... options)

Uploads a file to the Discord servers and sends it to this MessageChannel. Sends the provided Message with the uploaded file.
If you want to send a Message with the uploaded file, you can add the file to the MessageAction returned by sendMessage(Message).

sendFile(file, file.getName())

Uploading images with Embeds
When uploading an image you can reference said image using the specified filename as URI attachment://filename.ext.

Example

 MessageChannel channel; // = reference of a MessageChannel
 EmbedBuilder embed = new EmbedBuilder();
 File file = new File("cat.gif");
 embed.setImage("attachment://cat.gif")
      .setDescription("This is a cute cat :3");
 channel.sendFile(file).setEmbeds(embed.build()).queue();
 

For ErrorResponse information, refer to the documentation for sendFile(java.io.File, String, AttachmentOption...).

Parameters:

file - The file to upload to the MessageChannel.

options - Possible options to apply to this attachment, such as marking it as spoiler image

Returns:

MessageAction
Providing the Message created from this upload.

Throws:

IllegalArgumentException -

• Provided file is null.
• Provided file does not exist.
• Provided file is unreadable.
• Provided file is greater than 8 MiB on a normal or 50 MiB on a nitro account.

sendFile

@Nonnull
@CheckReturnValue
default MessageAction sendFile(@Nonnull
 File file,
 @Nonnull
 String fileName,
 @Nonnull
 AttachmentOption... options)

Uploads a file to the Discord servers and sends it to this MessageChannel. Sends the provided Message with the uploaded file.
If you want to send a Message with the uploaded file, you can add the file to the MessageAction returned by sendMessage(Message).

The fileName parameter is used to inform Discord about what the file should be called. This is 2 fold:

1. The file name provided is the name that is found in Message.Attachment.getFileName() after upload and it is the name that will show up in the client when the upload is displayed.
   Note: The fileName does not show up on the Desktop client for images. It does on mobile however.
2. The extension of the provided fileName also determines how Discord will treat the file. Discord currently only has special handling for image file types, but the fileName's extension must indicate that it is an image file. This means it has to end in something like .png, .jpg, .jpeg, .gif, etc. As a note, you can also not provide a full name for the file and instead ONLY provide the extension like "png" or "gif" and Discord will generate a name for the upload and append the fileName as the extension.

Uploading images with Embeds
When uploading an image you can reference said image using the specified filename as URI attachment://filename.ext.

Example

 MessageChannel channel; // = reference of a MessageChannel
 EmbedBuilder embed = new EmbedBuilder();
 File file = new File("cat_01.gif");
 embed.setImage("attachment://cat.gif") // we specify this in sendFile as "cat.gif"
      .setDescription("This is a cute cat :3");
 channel.sendFile(file, "cat.gif").setEmbeds(embed.build()).queue();
 

The following ErrorResponses are possible:

• MISSING_ACCESS
  The send request was attempted after the account lost access to the Guild typically due to being kicked or removed.
• MISSING_PERMISSIONS
  The send request was attempted after the account lost Permission.MESSAGE_SEND or Permission.MESSAGE_ATTACH_FILES in the TextChannel.
• CANNOT_SEND_TO_USER
  If this is a PrivateChannel and the currently logged in account does not share any Guilds with the recipient User
• UNKNOWN_CHANNEL
  The send request was attempted after the channel was deleted.

Parameters:

file - The file to upload to the MessageChannel.

fileName - The name that should be sent to discord

MessageHistory is NOT an internal message cache, but rather it queries the Discord servers for previously sent messages.

Returns:

Throws:

InsufficientPermissionException - If this is a TextChannel and the currently logged in account does not have the permission MESSAGE_HISTORY

getIterableHistory

@Nonnull
@CheckReturnValue
default MessagePaginationAction getIterableHistory()

A PaginationAction implementation that allows to iterate over recent Messages of this MessageChannel.
This is not a cache for received messages and it can only view messages that were sent before. This iterates chronologically backwards (from present to past).

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())
         );
 }
 

Returns:

MessagePaginationAction

Throws:

InsufficientPermissionException - If this is a TextChannel and the currently logged in account does not have the permission MESSAGE_HISTORY

@CheckReturnValue
default MessageHistory.MessageRetrieveAction getHistoryAround(@Nonnull

Examples:
Retrieve 100 messages from the middle of history. >100 message exist in history and the marker is >50 messages from the edge of history.
getHistoryAround(messageId, 100) - This will retrieve 100 messages from history, 50 before the marker and 50 after the marker.
