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)

Takes the order data of the given order, adds the length, the flow control flag and chain type to the front and copies that data to the channel cell buffer of the order.

Specified by:

createPacketPayload in class AbstractDataChain

run

public void run()

Specified by:

run in interface java.lang.Runnable

Specified by:
