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:KeyValueRequestEncode this request with the given allocator and opaque.- 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 GetMetaResponse decode(com.couchbase.client.core.deps.io.netty.buffer.ByteBuf response, KeyValueChannelContext ctx)
Description copied from interface:KeyValueRequestDecode the encoded response into its message representation.- Parameters:
response- the response to decode.- Returns:
- the decoded response as the generic type R.
-
idempotent
public boolean idempotent()
Description copied from interface:RequestReturns 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!
- Returns:
- true if idempotent.
