Flatpack Component

The Flatpack component supports fixed width and delimited file parsing via the FlatPack library.

URI format

flatpack:[delim|fixed]:flatPackConfig.pzmap.xml


or for a delimited file handler with no configuration file just use





flatpack:someName





Examples



    
	
  • flatpack:fixed:foo.pzmap.xml creates a fixed width endpoint using the foo.pzmap.xml file configuration
    • 
	
  • flatpack:delim:bar.pzmap.xml creates a delimited endpoint using the bar.pzmap.xml file configuration
    • 
	
  • flatpack:foo creates a delimited endpoint called foo with no file configuration
    • 





URI Options






 Name 
 Default Value 
 Description 




 delimiter 
 ',' 
 the default character delimiter for delimited files




 textQualifier 
 '"' 
 the text qualifier delimited files




 ignoreFirstRecord 
 true 
 whether the first line is ignored for delimited files (for the column headers)






Header and Trailer records


In Camel 1.5 onwards the header and trailer notions in Flatpack is supported. However it is required that you must use a fixed record id names


    
	
  • header for the header record (must be lowercase)
    • 
	
  • trailer for the trailer record (must be lowercase)
    • 





The example below illustrates this fact that we have a header and a trailer. You can omit one or both of them if not needed. 




<RECORD id="header" startPosition="1" endPosition="3" indicator="HBT">
        <COLUMN name="INDICATOR" length="3"/>
        <COLUMN name="DATE" length="8"/>
    </RECORD>

    <COLUMN name="FIRSTNAME" length="35" />
    <COLUMN name="LASTNAME" length="35" />
    <COLUMN name="ADDRESS" length="100" />
    <COLUMN name="CITY" length="100" />
    <COLUMN name="STATE" length="2" />
    <COLUMN name="ZIP" length="5" />

    <RECORD id="trailer" startPosition="1" endPosition="3" indicator="FBT">
        <COLUMN name="INDICATOR" length="3"/>
        <COLUMN name="STATUS" length="7"/>
    </RECORD>






Using the endpoint



A common use case is sending a file to this endpoint for further processing in a separate route. For example...





<camelContext xmlns="http://activemq.apache.org/camel/schema/spring">
    <route>
      <from uri="file://someDirectory"/>
      <to uri="flatpack:foo"/>
    </route>

    <route>
      <from uri="flatpack:foo"/>
      ...
    </route>
  </camelContext>





You can also convert the payload of each message created to a Map for easy Bean Integration
