guarana.util.observer.smart.SmartObservable
guarana.framework.task.Task

guarana.toolkit.task.routers.SemanticValidator
- All Implemented Interfaces:
- ISource, guarana.util.observer.smart.ISmartObserver
public abstract class SemanticValidator
- extends Router
Validates the semantics of an inbound message.
If log INFO level is activated, a semantic invalid message causes its MESSAGE_ID to be written to the log.
A semantic validator does not change the state of inbound messages.
It means the MESSAGE_ID is kept the same!
This task is normally used at post-receive stage of receiving locations.

SemanticValidator
public SemanticValidator(String name)
- Constructs a new semantic validator task.
- Parameters:
name
- The name of the semantic validator task.
SemanticValidator
public SemanticValidator(String name,
int numberOfInputs,
int numberOfOutputs)
- Constructs a new semantic validator task.
- Parameters:
name
- The name of this task.numberOfInputs
- The number of input gateways this task must have.numberOfOutputs
- The number of output gateways this task must have.
doWork
public abstract void doWork(Exchange exchange)
throws TaskExecutionException
- This method implements the business logic of this task.
Validates the semantics of the body content of the inbound message. The validation must be provided by the end user as the implementation of this method.
- Overrides:
doWork
in class Task
- Parameters:
exchange
- An exchange object that holds the inbound messages of this task.
- Throws:
TaskExecutionException
- to report any exception that has occurred during the execution of this method.
update
public void update(guarana.util.observer.smart.SmartObservable slot,
Object arg)
- This method is automatically called by the observable slot to notify the slot has received a message.
For all those tasks that can execute with one or more messages in its input slots, this method will add the
task to the executable task reporter, so it can be executed. In this case the task execution will consume messages
from all input slots.
Please, do not call this method by yourself.
Overrides the implementation at Task
for performance reasons.
- Specified by:
update
in interface guarana.util.observer.smart.ISmartObserver
- Overrides:
update
in class Task
- Parameters:
slot
- The Slot
associated with this task.arg
