Method Detail

getOpCode

public abstract Constants.OpCode getOpCode()

Obtain the operation code that this preprocessor will force into the command message

Returns:

Constants.OpCode

setJBPMContextParameters

public abstract void setJBPMContextParameters(Message request)

Some message values are fixed at action configuration time (from the jboss-esb.xml).
This method is responsible of stuffing these static values into every Message before passing it to the generic CommandInterpreter process(Message) method
Some of the Message content will thus come from configuration XML, and some will be the users' responsibility (e.g. processId, tokenId, etc)
Variable name mapping between esb and jBPM is also handled by this interface

Parameters:

request - Message - Into which the static values will be added

getFacade

public static MessageFacade getFacade(ConfigTree config)

                                      java.lang.UnsupportedOperationException
