Synchronize Status Listener

Retrieve the synchronization status.

Synchronize Status Listener is mainly for debugging and performance measuring purposes to monitor stages of a synchronize session. It could also be used in UI for synchronization progress status. Below is a sample Synchronize Status Listener.

import com.sybase.persistence.ObjectSyncStatusData;
import com.sybase.persistence.SyncStatusListener;
import com.sybase.persistence.SyncStatusState;

public class MySyncStatusListener implements SyncStatusListener
{
  long start;

  public MySyncStatusListener()
  {
    start = System.currentTimeMillis();
  }

  public boolean objectSyncStatus(ObjectSyncStatusData statusData)
  {
    long now = System.currentTimeMillis();
    long interval = now - start;
    start = now;
    String infoMessage;

    int syncState = statusData.getSyncStatusState();

    switch (syncState)
    {
      case SyncStatusState.SYNC_STARTING:
        infoMessage = "START [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_SYNC_SENDING_HEADER:
        infoMessage = "SENDING HEADERS [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_SYNC_SENDING_SCHEMA:
        infoMessage = "SENDING SCHEMA [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_DATA_UPLOADING:
        infoMessage = "DATA UPLOADING [" + interval + "] "
          + statusData.getCurrentMBO() + ": (S>"
          + statusData.getSentByteCount() + ":"
          + statusData.getSentRowCount() + " R<"
          + statusData.getReceivedByteCount() + ":"
          + statusData.getReceivedRowCount() + ")";
        break;
      case SyncStatusState.APPLICATION_SYNC_RECEIVING_UPLOAD_ACK:
        infoMessage = "RECEIVING UPLOAD ACK [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_DATA_UPLOADING_DONE:
        infoMessage = "UPLOAD DONE [" + interval + "] "
          + statusData.getCurrentMBO() + ": (S>"
          + statusData.getSentByteCount() + ":"
          + statusData.getSentRowCount() + " R<"
          + statusData.getReceivedByteCount() + ":"
          + statusData.getReceivedRowCount() + ")";
        break;
      case SyncStatusState.APPLICATION_DATA_DOWNLOADING:
        infoMessage = "DATA DOWNLOADING[" + interval + "] "
          + statusData.getCurrentMBO() + ": (S>"
          + statusData.getSentByteCount() + ":"
          + statusData.getSentRowCount() + " R<"
          + statusData.getReceivedByteCount() + ":"
          + statusData.getReceivedRowCount() + ")"; 
        break;
      case SyncStatusState.APPLICATION_SYNC_DISCONNECTING:
        infoMessage = "DISCONNECTING [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_SYNC_COMMITTING_DOWNLOAD:
        infoMessage = "COMMITTING DOWNLOAD [" + interval + "] "
          + statusData.getCurrentMBO() + ": (S>"
          + statusData.getSentByteCount() + ":"
          + statusData.getSentRowCount() + " R<"
          + statusData.getReceivedByteCount() + ":"
          + statusData.getReceivedRowCount() + ")";
        break;
      case SyncStatusState.APPLICATION_SYNC_CANCELLED:
        infoMessage = "SYNC CANCELED [" + interval + "]";
        break;
      case SyncStatusState.APPLICATION_DATA_DOWNLOADING_DONE:
        infoMessage = "DATA DOWNLOADING DONE [" + interval + "]";
        break;
      case SyncStatusState.SYNC_DONE:
        infoMessage = "DONE [" + interval + "]";
        break;
      default:
        infoMessage = "STATE" + syncState + "[" + interval + "]";
        break;
    }
    LogMessage(infoMessage);
    return false;
  }
}

The application can pass an instance of an implementation of SyncStatusListener to the synchronize API of the generated package database class to monitor the synchronization status.
