Constructor Details

MultiObserveViaCasRequest

public MultiObserveViaCasRequest(Duration timeout,
 CoreContext ctx,
 RetryStrategy retryStrategy,
 CollectionIdentifier collectionIdentifier,
 NodeIdentifier target,
 Map<byte[],Short> keys,
 Predicate<ObserveViaCasResponse.ObserveStatus> responsePredicate)

Method Details

encode

public com.couchbase.client.core.deps.io.netty.buffer.ByteBuf encode(com.couchbase.client.core.deps.io.netty.buffer.ByteBufAllocator alloc,
 int opaque,
 KeyValueChannelContext ctx)

Description copied from interface: KeyValueRequest

Encode this request with the given allocator and opaque.

Specified by:

encode in interface KeyValueRequest<MultiObserveViaCasResponse>

Parameters:

alloc - the allocator where to grab the buffers from.

opaque - the opaque value to use.

ctx - more encode context.

Returns:

the encoded request as a ByteBuf.

decode

public MultiObserveViaCasResponse 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<MultiObserveViaCasResponse>

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<MultiObserveViaCasResponse>

Returns:

(nullable)

idempotent

public boolean idempotent()

Description copied from interface: Request

Returns if the given request is idempotent or not.

By default, this method always returns false for data consistency reasons. Only specific idempotent operations should override this default since it impacts retry handling quite a bit. DO NOT SET THIS TO TRUE ON MUTATING OPERATIONS!

Specified by:

idempotent in interface Request<MultiObserveViaCasResponse>

Returns:

true if idempotent.

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<MultiObserveViaCasResponse>

Returns:

the name of the request type.

serviceContext

public Map<String,Object> serviceContext()

Description copied from interface: Request

Returns contextual information for each individual service.

Specified by:

serviceContext in interface Request<MultiObserveViaCasResponse>

Overrides:

serviceContext in class BaseKeyValueRequest<MultiObserveViaCasResponse>

Returns:

the service context.
