Method Detail

toString

public String toString()

Overrides:

toString in class Object

getTraceLabel

public String getTraceLabel()

Specified by:

getTraceLabel in interface org.apache.camel.Traceable

getExpression

public org.apache.camel.Expression getExpression()

getExceptionHandler

public org.apache.camel.spi.ExceptionHandler getExceptionHandler()

setExceptionHandler

public void setExceptionHandler(org.apache.camel.spi.ExceptionHandler exceptionHandler)

getBatchSize

public int getBatchSize()

setBatchSize

public void setBatchSize(int batchSize)

Sets the in batch size. This is the number of incoming exchanges that this batch processor will process before its completed. The default value is DEFAULT_BATCH_SIZE.

Parameters:

batchSize - the size

getOutBatchSize

public int getOutBatchSize()

setOutBatchSize

public void setOutBatchSize(int outBatchSize)

Sets the out batch size. If the batch processor holds more exchanges than this out size then the completion is triggered. Can for instance be used to ensure that this batch is completed when a certain number of exchanges has been collected. By default this feature is not enabled.

Parameters:

outBatchSize - the size

getBatchTimeout

public long getBatchTimeout()

setBatchTimeout

public void setBatchTimeout(long batchTimeout)

isGroupExchanges

setGroupExchanges

public void setGroupExchanges(boolean groupExchanges)

isBatchConsumer

public boolean isBatchConsumer()

setBatchConsumer

public void setBatchConsumer(boolean batchConsumer)

isIgnoreInvalidExchanges

public boolean isIgnoreInvalidExchanges()

setIgnoreInvalidExchanges

public void setIgnoreInvalidExchanges(boolean ignoreInvalidExchanges)

isReverse

public boolean isReverse()

setReverse

public void setReverse(boolean reverse)

isAllowDuplicates

public boolean isAllowDuplicates()

setAllowDuplicates

public void setAllowDuplicates(boolean allowDuplicates)

getCompletionPredicate

public org.apache.camel.Predicate getCompletionPredicate()

setCompletionPredicate
