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<DecrementResponse>

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 DecrementResponse 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<DecrementResponse>

Parameters:

response - the response to decode.

Returns:

the decoded response as the generic type R.

durabilityLevel

public Optional<DurabilityLevel> durabilityLevel()

Description copied from interface: SyncDurabilityRequest

Returns the durability level if present.

Specified by:

durabilityLevel in interface SyncDurabilityRequest

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<DecrementResponse>

Returns:

the name of the request type.
