SequentialChannelDataChain

public SequentialChannelDataChain(IDataChannelCreator a_channelCreator,
                                  DataChainErrorListener a_errorListener,
                                  IntegrityErrorListener a_integrityErrorListener,

Method Detail

getOutputBlockSize

public int getOutputBlockSize()

Description copied from interface: AnonChannel

Returns a value that indicates the current optimum size of data to write. Because often anon services transport the data fragmented into fixed sized packets for optimum performance it may be good to send data according to the packet size to avoid unneccessary overheads.

Specified by:

getOutputBlockSize in interface AnonChannel

Specified by:

getOutputBlockSize in class AbstractDataChain

Returns:

the current optimum size for output data. If 1 is returned the size does not matter.

createPacketPayload

public void createPacketPayload(DataChainSendOrderStructure a_order)

Description copied from class: AbstractDataChain

Creates the packet payload from the data stored in the given order. Additional information may be added depending on the type of data chain that is implementing this method.

The processed data will be stored in the channel cell of the order.

Specified by:

createPacketPayload in class AbstractDataChain

run

public void run()

Specified by:

run in interface java.lang.Runnable
