Class NodeIdentifier

java.lang.Object

org.apache.nifi.cluster.protocol.NodeIdentifier

public class NodeIdentifier
extends Object

A node identifier denoting the coordinates of a flow controller that is connected to a cluster. Nodes provide an external public API interface and an internal private interface for communicating with the cluster. The external API interface and internal protocol each require an IP or hostname as well as a port for communicating. This class overrides hashCode and equals and considers two instances to be equal if they have the equal IDs.

equals

public boolean equals(Object obj)

Compares the id of two node identifiers for equality.

Overrides:

equals in class Object

Parameters:

Compares API address/port and socket address/port for equality. The id is not used for comparison.

Parameters:

other - a node identifier

Returns:

true if API address/port and socket address/port are equal; false otherwise

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString
