  - aggregationStrategy
```
public AggregationStrategyClause<MulticastDefinition> aggregationStrategy()
```
    Sets the AggregationStrategy to be used to assemble the replies from the multicasts, into a single outgoing message from the Multicast using a fluent builder.
  - aggregationStrategy
```
public MulticastDefinition aggregationStrategy(org.apache.camel.AggregationStrategy aggregationStrategy)
```
    Sets the AggregationStrategy to be used to assemble the replies from the multicasts, into a single outgoing message from the Multicast. By default Camel will use the last reply as the outgoing message. You can also use a POJO as the AggregationStrategy. If an exception is thrown from the aggregate method in the AggregationStrategy, then by default, that exception is not handled by the error handler. The error handler can be enabled to react if enabling the shareUnitOfWork option.
  - aggregationStrategy
```
public MulticastDefinition aggregationStrategy(String aggregationStrategy)
```
    Sets a reference to the AggregationStrategy to be used to assemble the replies from the multicasts, into a single outgoing message from the Multicast. By default Camel will use the last reply as the outgoing message. You can also use a POJO as the AggregationStrategy. If an exception is thrown from the aggregate method in the AggregationStrategy, then by default, that exception is not handled by the error handler. The error handler can be enabled to react if enabling the shareUnitOfWork option.
  - aggregationStrategyMethodName
```
public MulticastDefinition aggregationStrategyMethodName(String methodName)
```
    This option can be used to explicit declare the method name to use, when using POJOs as the AggregationStrategy.
    
    Parameters:
    
    methodName - the method name to call
    
    Returns:
    
    the builder
  - aggregationStrategyMethodAllowNull
```
public MulticastDefinition aggregationStrategyMethodAllowNull()
```
    If this option is false then the aggregate method is not used if there was no data to enrich. If this option is true then null values is used as the oldExchange (when no data to enrich), when using POJOs as the AggregationStrategy
    
    Returns:
    
    the builder
  - parallelProcessing
```
public MulticastDefinition parallelProcessing()
```
    If enabled then sending messages to the multicasts occurs concurrently. Note the caller thread will still wait until all messages has been fully processed, before it continues. Its only the sending and processing the replies from the multicasts which happens concurrently.
    
    Returns:
    
    the builder
  - parallelProcessing
```
public MulticastDefinition parallelProcessing(boolean parallelProcessing)
```
    If enabled then sending messages to the multicasts occurs concurrently. Note the caller thread will still wait until all messages has been fully processed, before it continues. Its only the sending and processing the replies from the multicasts which happens concurrently.
    
    Returns:
    
    the builder
  - parallelAggregate
```
public MulticastDefinition parallelAggregate()
```
    If enabled then the aggregate method on AggregationStrategy can be called concurrently. Notice that this would require the implementation of AggregationStrategy to be implemented as thread-safe. By default this is false meaning that Camel synchronizes the call to the aggregate method. Though in some use-cases this can be used to archive higher performance when the AggregationStrategy is implemented as thread-safe.
    
    Returns:
    
    the builder
  - streaming
```
public MulticastDefinition streaming()
```
    If enabled then Camel will process replies out-of-order, eg in the order they come back. If disabled, Camel will process replies in the same order as defined by the multicast.
    
    Returns:
    
    the builder
  - stopOnException
```
public MulticastDefinition stopOnException()
```
    Will now stop further processing if an exception or failure occurred during processing of an Exchange and the caused exception will be thrown.
    Will also stop if processing the exchange failed (has a fault message) or an exception was thrown and handled by the error handler (such as using onException). In all situations the multicast will stop further processing. This is the same behavior as in pipeline, which is used by the routing engine.
    The default behavior is to not stop but continue processing till the end
    
    Returns:
    
    the builder
  - stopOnException
```
public MulticastDefinition stopOnException(String stopOnException)
```
    Will now stop further processing if an exception or failure occurred during processing of an Exchange and the caused exception will be thrown.
    Will also stop if processing the exchange failed (has a fault message) or an exception was thrown and handled by the error handler (such as using onException). In all situations the multicast will stop further processing. This is the same behavior as in pipeline, which is used by the routing engine.
    The default behavior is to not stop but continue processing till the end
    
    Returns:
    
    the builder
  - executorService
```
public MulticastDefinition executorService(ExecutorService executorService)
```
    To use a custom Thread Pool to be used for parallel processing. Notice if you set this option, then parallel processing is automatically implied, and you do not have to enable that option as well.
    
    Specified by:
    
    executorService in interface ExecutorServiceAwareDefinition<MulticastDefinition>
    
    Parameters:
    
    executorService - the executor service
    
    Returns:
    
    the builder
  - executorService
```
public MulticastDefinition executorService(String executorService)
```
    Refers to a custom Thread Pool to be used for parallel processing. Notice if you set this option, then parallel processing is automatically implied, and you do not have to enable that option as well.
    
    Specified by:
    
    executorService in interface ExecutorServiceAwareDefinition<MulticastDefinition>
    
    Parameters:
    
    executorService - reference for a ExecutorService to lookup in the Registry
    
    Returns:
    
    the builder
  - onPrepare
```
public ProcessClause<MulticastDefinition> onPrepare()
```
    Set the Processor to use when preparing the Exchange to be send using a fluent builder.
  - onPrepare
```
public MulticastDefinition onPrepare(org.apache.camel.Processor onPrepare)
```
    Uses the Processor when preparing the Exchange to be send. This can be used to deep-clone messages that should be send, or any custom logic needed before the exchange is send.
    
    Parameters:
    
    onPrepare - the processor
    
    Returns:
    
    the builder
  - onPrepare
```
public MulticastDefinition onPrepare(String onPrepare)
```
    Uses the Processor when preparing the Exchange to be send. This can be used to deep-clone messages that should be send, or any custom logic needed before the exchange is send.
    
    Parameters:
    
    onPrepare - reference to the processor to lookup in the Registry
    
    Returns:
    
    the builder
  - timeout
```
public MulticastDefinition timeout(long timeout)
```
    Sets a total timeout specified in millis, when using parallel processing. If the Multicast hasn't been able to send and process all replies within the given timeframe, then the timeout triggers and the Multicast breaks out and continues. Notice if you provide a TimeoutAwareAggregationStrategy then the timeout method is invoked before breaking out. If the timeout is reached with running tasks still remaining, certain tasks for which it is difficult for Camel to shut down in a graceful manner may continue to run. So use this option with a bit of care.
    
    Parameters:
    
    timeout - timeout in millis
    
    Returns:
    
    the builder
  - timeout
```
public MulticastDefinition timeout(String timeout)
```
    Sets a total timeout specified in millis, when using parallel processing. If the Multicast hasn't been able to send and process all replies within the given timeframe, then the timeout triggers and the Multicast breaks out and continues. Notice if you provide a TimeoutAwareAggregationStrategy then the timeout method is invoked before breaking out. If the timeout is reached with running tasks still remaining, certain tasks for which it is difficult for Camel to shut down in a graceful manner may continue to run. So use this option with a bit of care.
    
    Parameters:
    
    timeout - timeout in millis
    
    Returns:
    
    the builder
  - shareUnitOfWork
```
public MulticastDefinition shareUnitOfWork()
```
    Shares the UnitOfWork with the parent and each of the sub messages. Multicast will by default not share unit of work between the parent exchange and each multicasted exchange. This means each sub exchange has its own individual unit of work.
    
    Returns:
    
    the builder.
