Creates a typed Builder for Server customization.

Type Parameters:

T - The type of HttpServer

                                         Driver.Serialization serialization)

Sets the Service and Driver.Serialization information necessary to construct the appropriate AvaticaHandler.

Parameters:

service - The Avatica service

serialization - The serialization method

Returns:

this

withHandler

public HttpServer.Builder<T> withHandler(AvaticaHandler handler)

Sets an AvaticaHandler directly on the builder. Most users will not want to use this method and should instead use #withHandler(Service, Serialization).

Parameters:

handler - The handler

Returns:

this

withMetricsConfiguration

Sets the given configuration to enable metrics collection in the server.

Parameters:

metricsConfig - Configuration object for metrics.

Returns:

this

withSpnego

public HttpServer.Builder<T> withSpnego(String principal)

Configures the server to use SPNEGO authentication. This method requires that the principal contains the Kerberos realm. Invoking this method overrides any previous call which configures authentication.

Parameters:

principal - A kerberos principal with the realm required.

Returns:

this

withSpnego

@Deprecated
public HttpServer.Builder<T> withSpnego(String principal,
                                                    String[] additionalAllowedRealms)

Deprecated. Since 1.20.0, because additionalAllowedRealms is no longer considered.

Configures the server to use SPNEGO authentication. This method requires that the principal contains the Kerberos realm. Invoking this method overrides any previous call which configures authentication. Invoking this method overrides any previous call which configures authentication. By default, only principals from the server's realm are permitted, but additional realms can be allowed using additionalAllowedRealms.

Parameters:

principal - A kerberos principal with the realm required.

additionalAllowedRealms - Any additional realms, other than the server's realm, which should be allowed to authenticate against the server. Can be null.

Returns:

this

withSpnego

Configures the server to use SPNEGO authentication. It is required that callers are logged in via Kerberos already or have provided the necessary configuration to automatically log in via JAAS (using the java.security.auth.login.config system property) before starting the HttpServer. Invoking this method overrides any previous call which configures authentication.

Parameters:

principal - The kerberos principal

realm - The kerberos realm

Returns:

this

withSpnego
