@Forward(name="then",description="When a match is found.") @Forward(name="else",description="When no match is found.") @ElementType(ROUTER) 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>

    • 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.
