Package io.jmix.aichat.data

Class AbstractAiChatItems<T extends AiChatMessage>

java.lang.Object

io.jmix.aichat.data.AbstractAiChatItems<T>

Type Parameters:

T - the application's message type

All Implemented Interfaces:

AiChatItems<T>, DataUnit, Serializable

Direct Known Subclasses:

ContainerAiChatItems, ListAiChatItems

public abstract class AbstractAiChatItems<T extends AiChatMessage>
extends Object
implements AiChatItems<T>, Serializable

Base class for AiChatItems implementations: owns the lazily created event bus, the items-change notification, and the constant-ACTIVE data-unit state every source shares. Subclasses keep only their storage logic and call fireItemsChangeEvent(io.jmix.aichat.data.AiChatItems.ItemsChangeType, java.util.Collection<? extends T>) on mutation.
