Constructor Detail

SeekerState

public SeekerState(ObjectIntPair<ByteBuffer> tmpPair,
                   boolean includeTags)

Method Detail

isValid

protected boolean isValid()

invalidate

protected void invalidate()

ensureSpaceForKey

protected void ensureSpaceForKey()

ensureSpaceForTags

protected void ensureSpaceForTags()

setKey

protected void setKey(byte[] keyBuffer,
                      long memTS)

copyFromNext

protected void copyFromNext(BufferedDataBlockEncoder.SeekerState nextState)

Copy the state from the next one into this instance (the previous state placeholder). Used to save the previous state when we are advancing the seeker to the next key/value.

toCell

public Cell toCell()

toOnheapCell

private Cell toOnheapCell(ByteBuffer valAndTagsBuffer,
                          int vOffset,
                          int tagsLenSerializationSize)

toOffheapCell

private Cell toOffheapCell(ByteBuffer valAndTagsBuffer,
                           int vOffset,
                           int tagsLenSerializationSize)
