Package io.jmix.aichat.data

Class DefaultAiChatMessageFactory

java.lang.Object

io.jmix.aichat.data.DefaultAiChatMessageFactory

All Implemented Interfaces:

AiChatMessageFactory<SimpleAiChatMessage>, Serializable, Function<AiChatMessageContext,SimpleAiChatMessage>

@Component("aichat_DefaultAiChatMessageFactory")
public class DefaultAiChatMessageFactory
extends Object
implements AiChatMessageFactory<SimpleAiChatMessage>

The message factory AiChat falls back to when the application supplies none: it mints SimpleAiChatMessage instances and saves their attachments to the default file storage. This is the only place the add-on writes to FileStorage.

It fits the in-memory path, where the message type is SimpleAiChatMessage; an entity-backed source supplies its own factory instead, because the message contract is read-only and the component never creates entities itself. Replace it by declaring a @Primary bean of a subclass: getFileStorage() chooses where attachments go, saveAttachments(List) how they are stored, and apply(io.jmix.aichat.data.AiChatMessageContext) what message is built from the result.

public DefaultAiChatMessageFactory()

Method Details

apply

public SimpleAiChatMessage apply(AiChatMessageContext context)

Description copied from interface: AiChatMessageFactory

Creates a message for the given context. The factory owns persistence: for an entity source it saves each attachment's bytes to file storage and sets the resulting FileRefs on the created message.

Specified by:

apply in interface AiChatMessageFactory<SimpleAiChatMessage>

Specified by:

apply in interface Function<AiChatMessageContext,SimpleAiChatMessage>

Parameters:

context - what is known about the message to create

Returns:

the created message

saveAttachments

protected List<FileRef> saveAttachments(List<com.vaadin.flow.component.ai.common.AIAttachment> attachments)

Saves the given attachments and returns the references to them. An empty list is stored nowhere, so no file storage is resolved for a message without attachments.

Parameters:

attachments - the files attached to the message

Returns:

the references to the saved files, in the order the attachments were given

getFileStorage

protected FileStorage getFileStorage()

Returns the storage the attachments are saved to. Override to write to a named storage instead of the application's default one.

Returns:

the file storage
