TransactionErrorHandler

public TransactionErrorHandler(CamelContext camelContext,
                               Processor output,
                               Logger logger,
                               Processor redeliveryProcessor,

                               Predicate retryWhile)

Creates the transaction error handler.

Parameters:

camelContext - the camel context

output - outer processor that should use this default error handler

logger - logger to use for logging failures and redelivery attempts

redeliveryProcessor - an optional processor to run before redelivery attempt

redeliveryPolicy - policy for redelivery

handledPolicy - policy for handling failed exception that are moved to the dead letter queue

exceptionPolicyStrategy - strategy for onException handling

transactionTemplate - the transaction template

retryWhile - retry while

                       AsyncCallback callback)

Specified by:

process in interface AsyncProcessor

processInTransaction

protected void processInTransaction(Exchange exchange)
                             throws Exception

Throws:

doInTransactionTemplate

protected void doInTransactionTemplate(Exchange exchange)

processByErrorHandler

protected void processByErrorHandler(Exchange exchange)

Processes the Exchange using the error handler.

This implementation will invoke ensure this occurs synchronously, that means if the async routing engine did kick in, then this implementation will wait for the task to complete before it continues.

Parameters:

exchange - the exchange
