OrientDB-NET - GetClusters()

This method returns the clusters on the connected OrientDB database. The return value is a list of OCluster objects.

Retrieving Clusters

In cases where you need to operate on many, most or all clusters in a database, you may find it more efficient to retrieve all OCluster objects in a single call. You can do so using the GetClusters() method.

Syntax

List<OCluster> ODatabase.GetClusters(bool reload)

• reload Defines whether you want to reload the ODatabase instance before retrieving the clusters. Defaults to false.

Examples

For instance, as part of a logging operation, you might build a helper function to retrieve the available clusters from the database and to print their names to the console, before returning them for further operations.

using Orient.Client;
using System;

public List<OCluster> FetchClusters(ODatabase database,
    bool reload = false)
{
  // FETCH CLUSTERS
  List<OCluster> clusters = database.GetClusters(reload);

  // INITIALIZE CLUSTER NAMES LIST
  List<string> clusterNames;
  foreach(OCluster cluster in clusters)
  {
     // ADD CLUSTER NAME
     clusterNames.Add(cluster.Name);
  }

  // LOG TO CONSOLE
  Console.WriteLine("Retrieved Clusters: {0}",
    String.Join(', ', clusterNames));

  // RETURN CLUSTERS
  return clusters;
}
