    Search network node events

    This page contains information about the purpose and use of all search network events.

    ConfigurationCompleted event

    The ConfigurationCompleted event occurs when the search network configuration process is finished.

    IndexingCompleted event

    The IndexingCompleted event occurs when indexing of all enqueued documents is finished.

    DeletionCompleted event

    The DeletionCompleted event occurs when all enqueued deletions of documents are finished.

    OptimizationCompleted event

    The OptimizationCompleted event occurs when optimization of all nodes is finished.

    SynchronizationCompleted event

    The SynchronizationCompleted event occurs when synchronization with all nodes is finished.

    AttributeChangesCompleted event

    The AttributeChangesCompleted event occurs when all enqueued attribute changes are finished.

    StatusChanged event

    The StatusChanged event occurs when the search network status changes.

    DataExtracted event

    The DataExtracted event occurs when the data has been extracted from a document.

    DocumentIndexed event

    The DocumentIndexed event occurs when a document has been indexed.

    DocumentDeleted event

    The DocumentDeleted event occurs when a document has been deleted.

    ErrorOccurred event

    The ErrorOccurred event occurs when an error occurs in one of the nodes of the search network.

    IndexingProgressChanged event

    The IndexingProgressChanged event occurs when the progress of the indexing operation has changed.

    OptimizationProgressChanged event

    The OptimizationProgressChanged event occurs when the progress of the optimization operation has changed.

    Code example 

    node.getEvents().IndexingCompleted.add(new EventHandler() {
    @Override
    public void invoke(Object s, EventArgs e) {
        System.out.println("Indexing complete");
    }
});
node.getEvents().DeletionCompleted.add(new EventHandler() {
    @Override
    public void invoke(Object s, EventArgs e) {
        System.out.println("Deleting complete");
    }
});
node.getEvents().OptimizationCompleted.add(new EventHandler() {
    @Override
    public void invoke(Object s, EventArgs e) {
        System.out.println("Optimization complete");
    }
});
node.getEvents().SynchronizationCompleted.add(new EventHandler() {
    @Override
    public void invoke(Object s, EventArgs e) {
        System.out.println("Synchronization complete");
    }
});
node.getEvents().AttributeChangesCompleted.add(new EventHandler() {
    @Override
    public void invoke(Object s, EventArgs e) {
        System.out.println("Attribute changes complete");
    }
});
node.getEvents().StatusChanged.add(new EventHandler<StatusChangedEventArgs>() {
    @Override
    public void invoke(Object s, StatusChangedEventArgs e) {
        System.out.println("Status changed: " + e.getOldStatus().name() + " -> " + e.getNewStatus().name());
    }
});
node.getEvents().DataExtracted.add(new EventHandler<DataExtractedEventArgs>() {
    @Override
    public void invoke(Object s, DataExtractedEventArgs e) {
        System.out.println("Data extracted (" + e.getExtractorIndex() + "): " + e.getDocumentKey());
    }
});
node.getEvents().DocumentIndexed.add(new EventHandler<DocumentIndexedEventArgs>() {
    @Override
    public void invoke(Object s, DocumentIndexedEventArgs e) {
        System.out.println("Document indexed (" + e.getShardIndex() + "): " + e.getDocumentKey());
    }
});
node.getEvents().DocumentDeleted.add(new EventHandler<DocumentDeletedEventArgs>() {
    @Override
    public void invoke(Object s, DocumentDeletedEventArgs e) {
        System.out.println("Document deleted (" + e.getShardIndex() + "): " + e.getDocumentKey());
    }
});
node.getEvents().ErrorOccurred.add(new EventHandler<ErrorOccurredEventArgs>() {
    @Override
    public void invoke(Object s, ErrorOccurredEventArgs e) {
        System.out.println("Error occurred (" + e.getNodeIndex() + ", " + e.getServiceIndex() + "): " + e.getMessage());
    }
});
node.getEvents().IndexingProgressChanged.add(new EventHandler<NetworkIndexingProgressEventArgs>() {
    @Override
    public void invoke(Object s, NetworkIndexingProgressEventArgs e) {
        System.out.println("Indexing progress changed (" + e.getNodeIndex() + ", " + e.getServiceIndex() + "): " + e.getProgressPercentage());
    }
});
node.getEvents().OptimizationProgressChanged.add(new EventHandler<NetworkOptimizationProgressEventArgs>() {
    @Override
    public void invoke(Object s, NetworkOptimizationProgressEventArgs e) {
        System.out.println("Optimization progress changed (" + e.getNodeIndex() + ", " + e.getServiceIndex() + "): " + e.getProgressPercentage());
    }
});
