org.frankframework.core.TransactionAttributes

org.frankframework.pipes.AbstractPipe

org.frankframework.pipes.FixedForwardPipe

org.frankframework.pipes.CounterSwitchPipe

All Implemented Interfaces:

HasTransactionAttribute, IConfigurable, IConfigurationAware, IForwardTarget, INamedObject, IPipe, IScopeProvider, IWithParameters, EventThrowing, HasStatistics, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

@Forward(name="*",
         description="the exitState, based on the number of received messages")
@EnterpriseIntegrationPattern(ROUTER)
public class CounterSwitchPipe
extends FixedForwardPipe

Selects an exitState, based on the number of received messages by this pipe. The exitState is the difference (subtraction) between the divisor and the remainder of [number of received messages] modulus divisor. This will always be an integer between 1 and divisor, inclusive.

configure

public void configure()
               throws ConfigurationException

Description copied from class: FixedForwardPipe

checks for correct configuration of forward

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface IPipe

Overrides:

configure in class FixedForwardPipe

Throws:

ConfigurationException

doPipe

public PipeRunResult doPipe(Message message,
 PipeLineSession session)
                     throws PipeRunException

Description copied from interface: IPipe

This is where the action takes place. Pipes may only throw a PipeRunException, to be handled by the caller of this object. Implementations must either consume the message, or pass it on to the next Pipe in the PipeRunResult. If the result of the Pipe does not depend on the input, like for the FixedResultPipe, the Pipe can schedule the input to be closed at session exit, by calling Message.closeOnCloseOf(PipeLineSession, String) This allows the previous Pipe to release any resources (e.g. connections) that it might have kept open until the message was consumed. Doing so avoids connections leaking from pools, while it enables efficient streaming processing of data while it is being read from a stream.

Throws:

PipeRunException

getDivisor

public int getDivisor()

setDivisor

@Default("2")
public void setDivisor(int i)
