Package jakarta.enterprise.context

Interface Conversation

public interface Conversation

Allows the application to manage the conversation context by marking the current conversation as transient or long-running, specifying a conversation identifier, or setting the conversation timeout.

An instance may be injected:

 @Inject
 Conversation conversation;
 

The conversation timeout is a hint to the container that a conversation should not be destroyed if it has been active within the last given interval in milliseconds.

CDI Lite implementations are not required to provide support for conversations.
