Method fromCell

src/KeyValue.java:310–325

Transforms a protobuf Cell message into a KeyValue (HBase 0.95+). @param buf The buffer to de-serialize from. @param prev Another KeyValue previously de-serialized from the same buffer. Can be null. The idea here is that KeyValues often come in a sorted batch, and often share a num

(final CellPB.Cell cell, final KeyValue prev)

   * @return a new instance (guaranteed non-{@code null}).
