Method Details

decode

public KvPingResponse decode(com.couchbase.client.core.deps.io.netty.buffer.ByteBuf response,
 KeyValueChannelContext ctx)

Description copied from interface: KeyValueRequest

Decode the encoded response into its message representation.

Specified by:

decode in interface KeyValueRequest<NoopResponse>

Overrides:

decode in class NoopRequest

Parameters:

response - the response to decode.

Returns:

the decoded response as the generic type R.

target

public NodeIdentifier target()

Description copied from interface: Request

Returns the node that should service this request, or null to let the service locator decide.

Specified by:

target in interface Request<NoopResponse>

Returns:

(nullable)

serviceContext

public Map<String,Object> serviceContext()

Description copied from interface: Request

Returns contextual information for each individual service.

Specified by:

serviceContext in interface Request<NoopResponse>

Overrides:

serviceContext in class BaseKeyValueRequest<NoopResponse>

Returns:

the service context.

name

public String name()

Description copied from interface: Request

The unique name of the request, usually related to the type but not necessarily.

The default implementation is derived from the class name (i.e. FooRequest returns foo), but if that does not match up it should be overridden in the actual class.

Specified by:

name in interface Request<NoopResponse>

Overrides:

name in class NoopRequest

Returns:

the name of the request type.
