GetMetaResponse |
decode(com.couchbase.client.core.deps.io.netty.buffer.ByteBuf response,
KeyValueChannelContext ctx)
Decode the encoded response into its message representation.
|
com.couchbase.client.core.deps.io.netty.buffer.ByteBuf |
encode(com.couchbase.client.core.deps.io.netty.buffer.ByteBufAllocator alloc,
int opaque,
KeyValueChannelContext ctx)
Encode this request with the given allocator and opaque.
|
boolean |
idempotent()
Returns if the given request is idempotent or not.
|
String |
name()
The unique name of the request, usually related to the type but not necessarily.

KeyValueRequest
alloc
- the allocator where to grab the buffers from.opaque
- the opaque value to use.ctx
- more encode context.ByteBuf

KeyValueRequest
response
- the response to decode.public boolean idempotent()
Request
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!
public String name()
Request
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.
