                           throws Exception

Description copied from class: AbstractTranscoder

Perform the decoding of the received response.

Specified by:

doDecode in class AbstractTranscoder<LegacyDocument,Object>

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.

newDocument

public LegacyDocument newDocument(String id,
                                  int expiry,
                                  Object content,
                                  long cas)

Description copied from interface: Transcoder

Creates a new Document with the passed in information.

Use the one with the mutation token instead (Transcoder.newDocument(String, int, Object, long, MutationToken)).

Parameters:

id - the id of the document.

expiry - the document expiration.

content - the document content.

cas - the documents cas value.

Returns:

the created document.

newDocument

                                  MutationToken mutationToken)

Description copied from class: AbstractTranscoder

Default implementation for backwards compatibility.

Specified by:

newDocument in interface Transcoder<LegacyDocument,Object>

Overrides:

newDocument in class AbstractTranscoder<LegacyDocument,Object>

Parameters:

id - the id of the document.

expiry - the document expiration.
