• getWriteToWAL

  @Deprecated
  public boolean getWriteToWAL()

  Deprecated. Use getDurability() instead.

  Returns:

  true if edits should be applied to WAL, false if not

• setWriteToWAL

  @Deprecated
  public Mutation setWriteToWAL(boolean write)

  Deprecated. Use setDurability(Durability) instead.

  Method for retrieving the put's familyMap that is deprecated and inefficient.

  Returns:

  the map

• setFamilyMap

  @Deprecated
  public Mutation setFamilyMap(NavigableMap<byte[],List<org.apache.hadoop.hbase.KeyValue>> map)
