MessageEventProvider

Background and Use Cases

The decision platform has a built-in user message notification feature. When a third-party system needs to synchronize messages bidirectionally with the platform, this interface can be used to listen for platform message send events, enabling forwarding to external systems or triggering additional callbacks.

Interface Definition

package com.fr.decision.fun;

import com.fr.stable.fun.mark.Mutable;
import java.util.Map;

public interface MessageEventProvider extends Mutable {
    String MARK_STRING = "MessageEventProvider";
    int CURRENT_LEVEL = 1;

    void handleMessage(Map<String, Object> message);
}

The message parameter corresponds to a Message object containing the following fields: userId, username, datetime, createTime, message (message text), url, toasted, readed, type, urlType.

Supported Versions

Plugin Registration

Add the following node to plugin.xml:

<extra-decision>
    <MessageEventProvider class="your class name"/>
</extra-decision>

How It Works

All implementations are retrieved via ExtraDecisionClassManager.getInstance().getArray(MessageEventProvider.MARK_STRING). WebServiceActivator listens for the MessageEvent.HANDLE event, which is triggered after MessageService saves a message.

Notes

• Only the message send event can be monitored; events such as message read status changes are not observable
