    Replicator
    public abstract class AbstractReplicator
extends com.couchbase.lite.internal.core.BaseReplicator
    A replicator for replicating document changes between a local database and a target database. The replicator can be bidirectional or either push or pull. The replicator can also be one-shot or continuous. The replicator runs asynchronously, so observe the status to be notified of progress.

    • Method Detail

      • start

        public void start()
        Start the replicator.

      • start

        public void start​(boolean resetCheckpoint)
        Start the replicator. This method does not wait for the replicator to start. The replicator runs asynchronously and reports its progress through replicator change notifications.

      • stop

        public void stop()
        Stop a running replicator. This method does not wait for the replicator to stop. When it does actually stop it will a new state, STOPPED, to change listeners.

      • getConfig

        @NonNull
public ReplicatorConfiguration getConfig()
        The replicator's configuration.
        Returns:
        this replicator's configuration

      • getStatus

        @NonNull
public ReplicatorStatus getStatus()
        The replicator's current status: its activity level and progress. Observable.
        Returns:
        this replicator's status

      • getServerCertificates

        @Nullable
public java.util.List<java.security.cert.Certificate> getServerCertificates()
        The server certificates received from the server during the TLS handshake.
        Returns:
        this replicator's server certificates.

        @NonNull
public java.util.Set<java.lang.String> getPendingDocumentIds()
                                                      throws CouchbaseLiteException
        Get a best effort list of documents still pending replication.
        Returns:
        a set of ids for documents still awaiting replication.
        Throws:
        CouchbaseLiteException

      • isDocumentPending

        public boolean isDocumentPending​(@NonNull
                                 java.lang.String docId)
                          throws CouchbaseLiteException
        Best effort check to see if the document whose ID is passed is still pending replication.
        Parameters:
        docId - Document id
        Returns:
        true if the document is pending
        Throws:
        CouchbaseLiteException

      • addChangeListener

        @NonNull
public ListenerToken addChangeListener​(@NonNull
                                       ReplicatorChangeListener listener)
        Adds a change listener for the changes in the replication status and progress.

        The changes will be delivered on the UI thread for the Android platform On other Java platforms, the callback will occur on an arbitrary thread.

        When developing a Java Desktop application using Swing or JavaFX that needs to update the UI after receiving the changes, make sure to schedule the UI update on the UI thread by using SwingUtilities.invokeLater(Runnable) or Platform.runLater(Runnable) respectively.

        Parameters:
        listener - callback

      • addChangeListener

        @NonNull
public ListenerToken addChangeListener​(@Nullable
                                       java.util.concurrent.Executor executor,
                                       @NonNull
                                       ReplicatorChangeListener listener)
        Adds a change listener for the changes in the replication status and progress with an executor on which the changes will be posted to the listener. If the executor is not specified, the changes will be delivered on the UI thread on Android platform and on an arbitrary thread on other Java platform.
        Parameters:
        executor - executor on which events will be delivered
        listener - callback

      • addDocumentReplicationListener

        @NonNull
public ListenerToken addDocumentReplicationListener​(@NonNull
                                                    DocumentReplicationListener listener)
        Adds a listener for receiving the replication status of the specified document. The status will be delivered on the UI thread for the Android platform and on an arbitrary thread for the Java platform. When developing a Java Desktop application using Swing or JavaFX that needs to update the UI after receiving the status, make sure to schedule the UI update on the UI thread by using SwingUtilities.invokeLater(Runnable) or Platform.runLater(Runnable) respectively.
        Parameters:
        listener - callback
        Returns:
        A ListenerToken that can be used to remove the handler in the future.
