Class Segment<B>

java.lang.Object

com.datastax.oss.protocol.internal.Segment<B>

public class Segment<B>
extends Object

A container of Frames in protocol v5 and above. This is a new protocol construct that allows checksumming and compressing multiple messages together.

payload contains either:

• a sequence of encoded Frames, all concatenated together. In this case, isSelfContained is true.
• or a slice of an encoded large Frame (if that frame is longer than MAX_PAYLOAD_LENGTH). In this case, isSelfContained is false.

The payload is not compressed; compression is handled at a lower level when encoding or decoding this object.

Naming is provisional: it's possible that this type will be renamed to "frame", and Frame to something else, at some point in the future (this is an ongoing discussion on the server ticket).
