Interface EndPoint

public interface EndPoint

Encapsulates the information needed to open connections to a node.

By default, the driver assumes plain TCP connections, and this is just a wrapper around an InetSocketAddress. However, more complex deployment scenarios might use a custom implementation that contains additional information; for example, if the nodes are accessed through a proxy with SNI routing, an SNI server name is needed in addition to the proxy address.

Method Summary

Modifier and Type	Method and Description
String	asMetricPrefix() Returns an alternate string representation for use in node-level metric names.
SocketAddress	resolve() Resolves this instance to a socket address.

Method Detail

resolve

@NonNull
SocketAddress resolve()

Resolves this instance to a socket address.

This will be called each time the driver opens a new connection to the node. The returned address cannot be null.

asMetricPrefix

@NonNull
String asMetricPrefix()

Returns an alternate string representation for use in node-level metric names.

Because metrics names are path-like, dot-separated strings, raw IP addresses don't make very good identifiers. So this method will typically replace the dots by another character, for example 127_0_0_1_9042.
