All Implemented Interfaces:

AiChatItems<T>, DataUnit, Serializable

public class ListAiChatItems<T extends AiChatMessage>
extends AbstractAiChatItems<T>

In-memory AiChatItems implementation. This is the default source of an unbound AiChat, so a chat that was never given items can still generate into memory.

ListAiChatItems

public ListAiChatItems()

Creates an empty in-memory unit.

ListAiChatItems

public ListAiChatItems(Collection<T> items)

Creates a unit over a copy of the given messages, so mutations work even when the argument is immutable.

Parameters:

items - the initial messages

Method Details

getItems

public List<T> getItems()

Description copied from interface: AiChatItems

Returns the messages in render order. The returned list is not modifiable; use AiChatItems.addItem(AiChatMessage) and AiChatItems.removeItem(AiChatMessage) instead.

Returns:

the messages in render order

addItem

public void addItem(T item)

Description copied from interface: AiChatItems

Appends a message to the end of the conversation. Implementations must fire an AiChatItems.ItemsChangeEvent of type AiChatItems.ItemsChangeType.ADD — AiChat re-renders on that notification alone, so a silent mutation leaves the message unrendered.

Parameters:

item - the message to append

removeItem

public void removeItem(T item)

Description copied from interface: AiChatItems

Removes a message from the conversation. Does nothing when the message is not present. Implementations must fire an AiChatItems.ItemsChangeEvent of type AiChatItems.ItemsChangeType.REMOVE for an actual removal — AiChat re-renders on that notification alone, so a silent mutation leaves the message rendered.

Parameters:

item - the message to remove
