Method Detail

decode

public D decode(String id,
                com.couchbase.client.deps.io.netty.buffer.ByteBuf content,
                long cas,
                int expiry,
                int flags,
                ResponseStatus status)

Specified by:

decode in interface Transcoder<D extends Document<T>,T>

encode

public Tuple2<com.couchbase.client.deps.io.netty.buffer.ByteBuf,Integer> encode(D document)

Specified by:

encode in interface Transcoder<D extends Document<T>,T>

doDecode

protected abstract D doDecode(String id,
                              com.couchbase.client.deps.io.netty.buffer.ByteBuf content,
                              long cas,
                              int expiry,
                              int flags,
                              ResponseStatus status)
                       throws Exception

Perform the decoding of the received response.

Parameters:

id - the id of the document.

content - the encoded content of the document.

cas - the cas value of the document.

expiry - the expiration time of the document.

flags - the flags set on the document.

status - the response status.

Returns:

the decoded document.

Throws:

Exception - if something goes wrong during the decode process.

doEncode

protected abstract Tuple2<com.couchbase.client.deps.io.netty.buffer.ByteBuf,Integer> doEncode(D document)
                                                                                       throws Exception

Perform the encoding of the request document.

Parameters:

document - the document to encode.

Returns:

A tuple consisting of the encoded content and the flags to set.

Throws:

Exception - if something goes wrong during the encode process.

shouldAutoReleaseOnDecode

protected boolean shouldAutoReleaseOnDecode()

Flag method to auto release decoded buffers. Override to change default behaviour (true).

Returns:

true if the ByteBuf passed to decode method is to be released automatically on success (default behaviour)

shouldAutoReleaseOnError

protected boolean shouldAutoReleaseOnError()

Flag method to auto release buffers on decoding error. Override to change default behaviour (true).

Returns:

true if the ByteBuf passed to decode method is to be released automatically in case of error (default behaviour)

newDocument

public D newDocument(String id,
                     int expiry,
                     T content,
                     long cas,
                     MutationToken mutationToken)

Default implementation for backwards compatibility.

Specified by:

newDocument in interface Transcoder<D extends Document<T>,T>

Parameters:

id - the id of the document.

expiry - the document expiration.

content - the document content.

cas - the documents cas value.

mutationToken - the documents mutation token.

Returns:

the created document.
