Method Details

getSerializedSize

int getSerializedSize(T data)

Calculate the number of bytes taken by after serialization.

Parameters:

data - The object which called by TxnLogBufferedWriter.asyncAddData(T, org.apache.pulsar.transaction.coordinator.impl.TxnLogBufferedWriter.AddDataCallback, java.lang.Object).

Returns:

The number of bytes taken after serialization.

serialize

io.netty.buffer.ByteBuf serialize(T data)

Serialize to ByteBuf. The returned ByteBuf will be release once after writing to Bookie complete, and if you still need to use the ByteBuf, should call ByteBuf.retain() in serialize(Object) implementation.

Parameters:

data - The object which called by TxnLogBufferedWriter.asyncAddData(T, org.apache.pulsar.transaction.coordinator.impl.TxnLogBufferedWriter.AddDataCallback, java.lang.Object).

Returns:

byte buf.

serialize

io.netty.buffer.ByteBuf serialize(ArrayList<T> dataArray)

Serialize to ByteBuf. The returned ByteBuf will be release once after writing to Bookie complete, and if you still need to use the ByteBuf, should call ByteBuf.retain() in serialize(Object) implementation.

Parameters:

dataArray - The objects which called by TxnLogBufferedWriter.asyncAddData(T, org.apache.pulsar.transaction.coordinator.impl.TxnLogBufferedWriter.AddDataCallback, java.lang.Object).

Returns:

byte buf.
