Field Detail

method_name

public static final String method_name

A method with this name must be provided by all post processing classes. The process(ResultingStructure) method of a certain postProc-class is called for all elements which are declared

  with ... postproc  <pathToPostProcClass>, ...

Post processing is a functional transformation: ResultingStructure is passed as an argument, and the same or a newly created different, (or the same, but modified) is returned as result. If null is returned, then the pre-processed element is totally dropped from the output.
