Class StmBodyTypeSelector

java.lang.Object

org.chenile.workflow.service.stmcmds.StmBodyTypeSelector

All Implemented Interfaces:

Command<ChenileExchange>

public class StmBodyTypeSelector
extends Object
implements Command<ChenileExchange>

Selects the body type of the ChenileExchange based on the event Id passed This should be used as the body type selector for the StateEntityServiceImpl.process(org.chenile.stm.StateEntity, String, Object) method. Will work with all subclasses. Assumptions:

1. Second parameter for the process method will be mapped to a header parameter called "eventId".
2. The body type has been defined in the stm in a states/event-information section. eventId must be mapped to meta attribute called "meta-bodyType"

ClassNotFoundException

checkIfPayloadTypeCanBeDerived

private tools.jackson.core.type.TypeReference<?> checkIfPayloadTypeCanBeDerived(String eventId)

This method works only if the eventID is the same as the name of the STMTransitionAction in the bean factory. It only works if the STMTransitionAction extends AbstractSTMTransitionAction. It computes the body type from the second argument of the AbstractSTMTransitionAction.transitionTo(StateEntityType, PayloadType, State, String, State, STMInternalTransitionInvoker, Transition) method that was overridden by the transition action.

public Map<String, StmBodyTypeSelector.EventData> getConfigs()
