public class RegExPipe
extends AbstractPipe

Tries to match the input against the provided regex.

 	<RegExPipe name="regExPipe" regex="^(.*?)(name!)$" flags="CASE_INSENSITIVE">
 		<Forward name="then" path="EXIT" />

Input:

 	Hello name!
 

Output:

  <matches>
 		<match index="1" value="Hello name!">
 			<group index="1">Hello </group>
 			<group index="2">name!</group>
 		</match>
  </matches>

public RegExPipe()

Method Details

configure

public void configure()
               throws ConfigurationException

Description copied from class: AbstractPipe

configure() is called after the Pipeline is registered at the Adapter. Purpose of this method is to reduce creating connections to databases etc. in the doPipe() method. As much as possible class-instantiating should take place in the configure() method, to improve performance.

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface IPipe

Overrides:

configure in class AbstractPipe

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

setRegex

@Mandatory
public void setRegex(String regex)

The regex expression to match against the input.

setFlags

public void setFlags(RegExPipe.RegExFlag... flags)

Comma seperated list of flags, which changes the behavior of the regex expression.
