Class CouchbaseNode

java.lang.Object

com.couchbase.client.core.state.AbstractStateMachine<LifecycleState>

com.couchbase.client.core.node.CouchbaseNode

All Implemented Interfaces:

Node, Stateful<LifecycleState>

public class CouchbaseNode
extends AbstractStateMachine<LifecycleState>
implements Node

The general implementation of a Node.

A Node manages one or more Services. When a node gets connected, all currently configured Services are connected. Those can and will also be added and removed on demand. On disconnect, all services will be shut down asynchronously and then the node is determined to be shutdown.

A Nodes states is composed exclusively of the underlying Service states.

send in interface Node

Parameters:

request - the request to send.

hostname

public NetworkAddress hostname()

Description copied from interface: Node

Returns the configured hostname for the Node.

public rx.Observable<Service> addService(AddServiceRequest request)

Specified by:

addService in interface Node

removeService

public rx.Observable<Service> removeService(RemoveServiceRequest request)

Specified by:

removeService in interface Node

healthCheck

public rx.Observable<EndpointHealth> healthCheck()

Description copied from interface: Node

Returns endpoint health information for all endpoints this node is currently associated with.

Specified by:

healthCheck in interface Node

hostname - the address.

Returns:

a prefix string for logs.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

serviceEnabled
