public interface Serializer

Main interface for "serializeable something" in Druid segment serialization.

Method Summary

Modifier and Type	Method and Description
long	getSerializedSize() Returns the number of bytes, that this Serializer will write to the output _channel_ (not smoosher) on a writeTo(java.nio.channels.WritableByteChannel, io.druid.java.util.common.io.smoosh.FileSmoosher) call.
void	writeTo(WritableByteChannel channel, FileSmoosher smoosher) Writes serialized form of this object to the given channel.

Method Detail

getSerializedSize

long getSerializedSize()
                throws IOException

Returns the number of bytes, that this Serializer will write to the output _channel_ (not smoosher) on a writeTo(java.nio.channels.WritableByteChannel, io.druid.java.util.common.io.smoosh.FileSmoosher) call.

Throws:

IOException

writeTo

void writeTo(WritableByteChannel channel,
             FileSmoosher smoosher)
      throws IOException

Writes serialized form of this object to the given channel. If parallel data streams are needed, they could be created with the provided smoosher.

Throws:

IOException
