Enclosing class:: AbstractSerializablePairLongObjectBufferStore<T extends SerializablePair<Long,?>>

public static class AbstractSerializablePairLongObjectBufferStore.TransferredBuffer extends Object implements Serializer

contains serialized data that is compressed and delta-encoded (Long) It's ready to be transferred to a WritableByteChannel

Constructor Details
- TransferredBuffer
  
  public TransferredBuffer(CellWriter cellWriter, AbstractSerializablePairLongObjectColumnHeader<?> columnHeader)
Method Details
- getSerializedSize
  
  public long getSerializedSize()
  
  Description copied from interface: Serializer
  
  Returns the number of bytes, that this Serializer will write to the output _channel_ (not smoosher) on a Serializer.writeTo(java.nio.channels.WritableByteChannel, org.apache.druid.java.util.common.io.smoosh.FileSmoosher) call.
  
  Specified by:
  
  getSerializedSize in interface Serializer
- writeTo
  
  public void writeTo(WritableByteChannel channel, FileSmoosher smoosher) throws IOException
  
  Description copied from interface: Serializer
  Writes the serialized form of this object. The entire object may be written to the provided channel, or the object may be split over the provided channel and files added to the
  
  invalid @link
  
  {@link FileSmoosher],
  
  where additional channels can be created via FileSmoosher.addWithSmooshedWriter(String, long). The latter approach is useful when the serialized form of the object is too large for a single smoosh container. At the time this javadoc was written, the max smoosh container size is limit to the max ByteBuffer size.

  writeTo in interface Serializer
  
  Throws:
  
  IOException
