Interface NodeTypeProvider

All Known Implementing Classes:
StandaloneNodeTypeProvider
public interface NodeTypeProvider
This interface provides a set of methods for checking NiFi node type.

  • Method Details

    • isClustered

      boolean isClustered()
      Returns:
      true if this instance is clustered, false otherwise.MockProcessContext Clustered means that a node is either connected or trying to connect to the cluster.

    • isConfiguredForClustering

      default boolean isConfiguredForClustering()
      Returns:
      true if the expected state of clustering is true, false otherwise. Contrary to {isClustered()} this does not dynamically change with the state of this node.

    • isConnected

      default boolean isConnected()
      Returns:
      true if this instances is clustered and connected to the cluster.

    • isPrimary

      boolean isPrimary()
      Returns:
      true if this instance is the primary node in the cluster; false otherwise

    • getCurrentNode

      default Optional<String> getCurrentNode()
      Returns:
      Returns with the hostname of the current node, if clustered. For For a standalone NiFi this returns an empty instead.

    • getClusterMembers

      default Set<String> getClusterMembers()
      Returns:
      Names/IP addresses of all expected hosts in the cluster (including the current one). For a standalone NiFi this returns an empty set instead.
