Enum Class EtcdSchemaRWConnectionFactory

java.lang.Object

java.lang.Enum<EtcdSchemaRWConnectionFactory>

io.deephaven.kv.etcd.EtcdSchemaRWConnectionFactory

All Implemented Interfaces:

Serializable, Comparable<EtcdSchemaRWConnectionFactory>, java.lang.constant.Constable

public enum EtcdSchemaRWConnectionFactory
extends Enum<EtcdSchemaRWConnectionFactory>

This class manages a single underlying etcd connection (client) instance on behalf of its clients. The etcd client instance provides the EtcdSchemaRWRole Users of this class transparently share the underlying etcd client. By calling getClientCreator() they get a wrapper object that should be closed by the caller when it is no longer necessary; the wrapper ensures that the last active user of the underlying client closes it. The class creates a new client if a new call to getInstance() happens after that.
