Interface MessageChannel

All Superinterfaces:

java.util.Formattable, ISnowflake

All Known Subinterfaces:

Group, PrivateChannel, TextChannel

public interface MessageChannel
extends ISnowflake, java.util.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 getName() rather than Object.toString()!
Supported Features:

• Alternative
  - Prepends the name with # (Example: %#s - results in #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 #getName() format as alternative

Method Detail

getLatestMessageId

default java.lang.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:

java.lang.IllegalStateException - If no message id is available

getLatestMessageIdLong

long getLatestMessageIdLong()

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

Returns:

The most recent message's id

Throws:

java.lang.IllegalStateException - If no message id is available

hasLatestMessage

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 IllegalStateException

Returns:

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

Parameters:

file - The file to upload to the MessageChannel.

message - The message to be sent along with the uploaded file. This value can be null.

Returns:

RestAction - Type: Message
The Message created from this upload.

Throws:

java.lang.IllegalArgumentException -

sendFile

@CheckReturnValue
default RestAction<Message> sendFile(java.io.File file,
                                                        java.lang.String fileName,
                                                        Message message)

Uploads a file to the Discord servers and sends it to this MessageChannel. Sends the provided Message with the uploaded file.
If you do not wish to send a Message with the uploaded file, you can provide null for the message parameter.

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 who 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.

The following ErrorResponses are possible:

• MISSING_ACCESS
  The send request was attempted after the account lost access to the Guild or Group typically due to being kicked or removed.
• MISSING_PERMISSIONS
  The send request was attempted after the account lost Permission.MESSAGE_WRITE or Permission.MESSAGE_ATTACH_FILES in the TextChannel.
• UNAUTHORIZED
  If this is a PrivateChannel and the recipient User blocked you
• 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

message - The message to be sent along with the uploaded file. This value can be null.

Returns:

RestAction - Type: Message
The Message created from this upload.

Throws:

java.lang.IllegalArgumentException -

• Provided file is null.
• Provided file does not exist.
• Provided file is unreadable.
• Provided file is greater than 8MB.

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 boolean containsMessage(MessageChannel channel, String content, int checkAmount)
 {
     for (Message message : channel.getIterableHistory())
     {
         if (message.getRawContent().equals(content))
             return true;
         if (checkAmount-- <= 0) break;
     }
     return false;
 }

 public List <Message> getMessagesByUser(MessageChannel channel, User user)
 {
     return channel.getIterableHistory().stream()
         .limit(1000)
         .filter(m -> m.getAuthor().equals(user))
         .collect(Collectors.toList());

Uses the provided Message as a marker and retrieves messages around the marker. The limit determines the amount of message retrieved near the marker. Discord will attempt to evenly split the limit between before and after the marker, however in the case that the marker is set near the beginning or near the end of the channel's history the amount of messages on each side of the marker may be different, and their total count may not equal the provided limit.

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(message, 100) - This will retrieve 100 messages from history, 50 before the marker and 50 after the marker.

Retrieve 10 messages near the end of history. Provided message is the 3rd most recent message.
getHistoryAround(message, 10) - This will retrieve 10 messages from history, 8 before the marker and 2 after the marker.

The following ErrorResponses are possible:

• MISSING_ACCESS
  The request was attempted after the account lost access to the Guild or Group typically due to being kicked or removed, or after Permission.MESSAGE_READ was revoked in the TextChannel
• MISSING_PERMISSIONS
  The request was attempted after the account lost Permission.MESSAGE_HISTORY in the TextChannel.
• UNKNOWN_MESSAGE
  The provided message has already been deleted, thus could not be used as a marker.
• UNKNOWN_CHANNEL
  The request was attempted after the channel was deleted.

Parameters:

message - The Message that will act as a marker. The provided Message must be from this MessageChannel.

limit - The amount of message to be retrieved around the marker. Minimum: 1, Max: 100.

Returns:

RestAction - Type: MessageHistory
Provides a MessageHistory object with message around the provided message loaded into it.

Throws:

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.
