Method Detail

process

public byte[] process(PreparedCommand pc)

Description copied from interface: CommandPostprocessor

processes the command and returns the binary buffer. Returns null if the command cannot be processed (e.g. its size does not correspond to what this processor expects). In this case the postprocessor is expected to fail the command in the command history (also filling in an appropiate reason)

Specified by:

process in interface CommandPostprocessor

Returns:

getBinaryLength

public int getBinaryLength(PreparedCommand pc)

Description copied from interface: CommandPostprocessor

Return the size of the binary packet for this command.

This is required in the frame links which bundle multiple commands together to know if the command will fit into the frame before post-processing it.

Specified by:

getBinaryLength in interface CommandPostprocessor

Returns:

the size of the binary packet which the method CommandPostprocessor.process(PreparedCommand) will return.

setCommandHistoryPublisher

public void setCommandHistoryPublisher(CommandHistoryPublisher commandHistoryListener)

Description copied from interface: CommandPostprocessor

sets the command history listener which can be used by the preprocessor to provide command history entries related to the command processed

Specified by:

setCommandHistoryPublisher in interface CommandPostprocessor

getMiniminimumTcPacketLength

public int getMiniminimumTcPacketLength()
