Package com.databricks.jdbc.dbclient.impl.http

Class ClosedConnectionHttpClient

java.lang.Object

com.databricks.jdbc.dbclient.impl.http.ClosedConnectionHttpClient

All Implemented Interfaces:

IDatabricksHttpClient

public final class ClosedConnectionHttpClient
extends Object
implements IDatabricksHttpClient

Sentinel HTTP client returned for connections that have been closed. All operations throw DatabricksHttpException with a clear message, so callers that accidentally store and use a post-close client get an immediate, diagnosable failure instead of a silent null.

Symmetric with NoopTelemetryClient which serves the same role for telemetry clients.
